It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect. Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses. Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke. <h2>What are the signs and symptoms?</h2> If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness. Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower. If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma. Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water. When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second. <h2>Why do we overheat?</h2> Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat. When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings. Sweating is by far our most effective physiological means of keeping cool. However, it is the evaporation of sweat from our skin that provides cooling relief. When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates. Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature. Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool. <h2>Who is most vulnerable in the heat?</h2> Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability. Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable. When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>. However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017. This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys. People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke. In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult. <h2>How to stay safe in the heat</h2> Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

Heated argument between economy passengers reignites plane etiquette debate

A 12-second clip of two passengers arguing on a plane has reignited the age-old debate of whether it is acceptable to recline your seat on a plane. The viral video which was originally posted on TikTok and then re-shared on X, has racked up over 8 million views since Thursday. In the video, a frustrated woman was calling out another female passenger for pushing her seat the entire flight, right after they landed. “The whole trip she pushed my seat,” the woman said to a male passenger seated next to the female passenger accused of kicking her seat. “You seen it. You know she did.” “I’m allowed to put my seat back," she yelled repeatedly. Ian Miles Cheong, the user who posted the video on X, defended the woman saying: “She’s allowed to put her seat back. You don’t get to kick it repeatedly just because you want more space.” A few were on the woman's side and praised her for standing up for herself. “You are allowed! Period! You want space in front of you instead of pushing the seat, buy a seat with extra space or get your a** to business class. Reclining was put there for a reason,” one person wrote. “She was patient enough to wait till flight landed," they added. “If the seat is reclinable, recline it,” another commented. "What she’s saying is right. The woman has a right to put her seat back without someone kicking it," a third agreed. <blockquote class="twitter-tweet"> She’s allowed to put her seat back. You don’t get to kick it repeatedly just because you want more space. <a href="https://t.co/WELD7Qh4Re">pic.twitter.com/WELD7Qh4Re</a> — Ian Miles Cheong (@stillgray) <a href="https://twitter.com/stillgray/status/1719881310351863952?ref_src=twsrc%5Etfw">November 2, 2023</a></blockquote> However, others claimed that there was an unwritten rule that you shouldn't recline your seat, especially on a short-haul flight, adding that the recline feature should be scrapped from airplanes. “Putting your seat back in coach is an unspoken thing most people don’t do. It’s really the airline’s fault because they’ve made coach so cramped and tight that putting the seat back shouldn’t even be an option,” one commented. “Airline seats simply shouldn’t be able to recline. It intrudes on the already very little space a person has on the plane for the person behind them,” another added. “Really it’s the airline’s fault for cramming so many people in such a small space. They don’t call it cattle class for nothing,” a third wrote. One user understood both sides of the argument, and blamed the airlines for making the seats so cramped. "It can be annoying sometimes to be behind someone with their seat all the way, but if the airlines didn't want to allow that, it wouldn't happen," they wrote. "You don't kick the seat like a baby. Blame the airline, not the person doing what the airline says is fine." Images: Twitter

4 ways to support someone with dementia during extreme heat

<a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Our ability to adapt our behaviour to changes in temperature takes a significant amount of thought and decision making. For example, we need to identify suitable clothing, increase our fluid intake, and understand how to best keep the house cool. A person with dementia may find some or all these things challenging. These and other factors mean, for someone with dementia, extreme heat <a href="https://pubmed.ncbi.nlm.nih.gov/31520832/#:%7E:text=Conclusion%3A%20Heatwaves%20increased%20the%20risk,heat%2Drelated%20Alzheimer's%20disease%20burden.">can be deadly</a>. But as the temperature rises, friends, relatives and carers can help. <h2>El Niño means there are challenges ahead</h2> The recent declaration of <a href="https://www.abc.net.au/news/2023-09-19/bureau-of-meteorology-el-nino-blog/102875154">another El Niño</a> means we need to think about how we can best support those more vulnerable to be safe during the warmer months. Extreme heat and bushfires bring unique challenges for someone with dementia. Bushfires have a significant impact on older people’s mental health. But they generally <a href="https://www.health.act.gov.au/sites/default/files/2023-03/PATH_Impact%20of%202019-20%20Bushfires%20on%20a%20Cohort%20of%20Older%20Adults_REPORT_V3_0.pdf">bounce back</a> quickly. However, for someone with dementia, extreme heat can lead to a <a href="https://www.sciencedirect.com/science/article/pii/S0013935119305110">significant deterioration</a> in their overall health and they may not recover. Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead. <h2>Why are people with dementia more at risk?</h2> Dementia can affect the parts of the brain that help <a href="https://academic.oup.com/brain/article/138/11/3360/332653?login=true">regulate</a> our body temperature. Some <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243665">medications</a> can also increase someone’s sensitivity to heat. Problems with memory and thinking associated with dementia <a href="https://www.alzheimers.org.uk/get-support/daily-living/drinking-hydration">means</a> remembering to drink or communicating you are thirsty can be challenging. Heat can affect everyone’s mood. But if someone with dementia becomes dehydrated this can <a href="https://www.alzdiscovery.org/cognitive-vitality/blog/can-dehydration-impair-cognitive-function">increase</a> confusion and agitation, making it harder for them to know how to cool down. A person with dementia can also wander and become lost, which can be dangerous in extreme heat. <h2>4 ways to support someone with dementia</h2> 1. Avoid dehydration and heatstroke Try to avoid dehydration by encouraging someone to drink throughout the day. It’s better to have <a href="https://pubmed.ncbi.nlm.nih.gov/31769256/">small amounts</a> of liquid regularly instead of a large amount all at once. Little and often will help maximise hydration while avoiding sudden trips to <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/dementia-continence-issues#causes-of-incontinence-in-people-with-dementia">the bathroom</a>. Try to offer different types of drinks, or ice blocks. Placing drinks in sight can help as a reminder to drink. Choose foods with a high liquid content, such as fruit, salads, cool broths and yoghurt. Look out for <a href="https://www.nia.nih.gov/health/hot-weather-safety-older-adults#:%7E:text=Signs%20of%20heat%20stroke%20are,as%20under%20shade%20or%20indoors.">signs of heatstroke</a>, such as increased confusion beyond what the person would usually experience. Heatstroke may be more difficult to spot in someone living with dementia so it is important to check in when possible and to help them cool down if needed. 2. Cool the home Try to modify their home to make it easier to stay cool. Some air-conditioners have complex settings so make sure the temperature is set appropriately and the person with dementia knows how to use the controls. It is important to keep blinds and curtains shut where possible to reduce heat. However, ensure the <a href="https://www.scie.org.uk/dementia/supporting-people-with-dementia/dementia-friendly-environments/lighting.asp">lighting is adequate</a> to avoid falls. Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available. 3. Think about communications early If someone with dementia lives alone, consider how you will maintain contact in an emergency. Some people may not realise many landlines don’t work in a power outage, and of course, mobile phones can’t be recharged. Ensure the person with dementia has access to an <a href="https://www.telstra.com.au/support/category/home-phone/uninterruptible-power-supply">uninterruptable power supply</a>. This can help maintain communication for a few hours in a blackout. 4. Have an evacuation plan In case of fire, flash flooding or severe storm, <a href="https://dementiaresearch.org.au/wp-content/uploads/2017/10/2447_DCRC_Prep_natural_disaster_EBook_5.pdf">have an evacuation plan</a>. If the person with dementia attends a day or respite centre, know their plan too. The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues. Understand that someone with dementia may become distressed when their routine is disrupted. So be prepared with some simple activities or comfort items, current medications, and any specific medical information. Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible. <h2>We can all help</h2> It’s not just carers of people with dementia who can help. We can all ensure people with dementia stay safe and cool this spring and summer. So remember to check in on your relatives, friends and neighbours or arrange for someone to do so on your behalf.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213987/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Cooking (and heating) without gas: what are the impacts of shifting to all-electric homes?

<a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Gas connections for all new housing and sub-divisions will be <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">banned in Victoria</a> from January 1 next year. The long-term result of the state government’s significant change to planning approvals will be all-electric housing. The ACT made <a href="https://www.climatechoices.act.gov.au/policy-programs/preventing-new-gas-network-connections">similar changes</a> early this year, in line with a shift away from gas across <a href="https://www.bbc.com/news/science-environment-47559920">Europe</a> and <a href="https://www.theguardian.com/environment/2023/jan/19/gas-stove-culture-war-united-states">other locations</a>, although the NSW Premier Chris Minns has <a href="https://www.theguardian.com/australia-news/2023/jul/31/nsw-wont-ban-gas-in-new-homes-as-premier-declares-i-dont-need-another-complication">baulked</a> at doing the same. Around <a href="https://www.energy.vic.gov.au/renewable-energy/victorias-gas-substitution-roadmap">80% of homes</a> in Victoria are connected to gas. This high uptake was driven by gas being seen as more affordable and sustainable than electricity over past decades. The situation has <a href="https://www.iea.org/events/net-zero-by-2050-a-roadmap-for-the-global-energy-system">changed dramatically</a> as renewable electricity generation increases and <a href="https://www.abc.net.au/news/2023-07-27/aemo-wholesale-electricity-prices-fall-impact-power-bills/102654498">costs fall</a>. <a href="https://theconversation.com/all-electric-homes-are-better-for-your-hip-pocket-and-the-planet-heres-how-governments-can-help-us-get-off-gas-207409">Research</a> has suggested for more than a decade that the benefits of all-electric homes <a href="https://bze.org.au/research_release/energy-efficient-buildings-plan/">stack up in many locations</a>. New homes built under mandatory building energy performance standards (increasing from <a href="https://thefifthestate.com.au/innovation/building-construction/victoria-kicks-the-can-down-the-road-again-on-the-national-construction-code/">6 to 7 stars</a> in Victoria in May 2024) need smaller, cheaper heating and cooling systems. Installing reverse-cycle air conditioning for cooling provides a cost-effective heater as a bonus. Savings from not requiring gas pipes, appliances and gas supply infrastructure help to offset the costs of highly efficient electric appliances. Mandating fully electric homes means economies of scale will further reduce costs. <h2>How does this ban help?</h2> To achieve environmentally sustainable development, reforms of planning policy and regulation <a href="https://theconversation.com/sustainable-cities-australias-building-and-planning-rules-stand-in-the-way-of-getting-there-84263">are essential</a> to convert innovation and best practice to mainstream practice. Planning policy is particularly important for apartment buildings and other housing that may be rented or have an owners’ corporation. Retrofits to improve energy efficiency can be difficult in these situations. Banning gas in new and renovated housing will <a href="https://grattan.edu.au/report/getting-off-gas/">cut greenhouse gas emissions</a>. It’s also <a href="https://theconversation.com/gas-cooking-is-associated-with-worsening-asthma-in-kids-but-proper-ventilation-helps-151591">healthier for households</a> and <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/research-reports/the-victorian-healthy-homes-program-research-findings">reduces healthcare costs</a> as well as <a href="https://grattan.edu.au/report/getting-off-gas/">energy bills and infrastructure costs</a>. The Victorian government suggests the change will save all-electric households <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">about $1,000 a year</a>. Houses with solar will be even better off. The government appears to be offering wide support to ensure these changes happen, but this will need to be monitored closely. Some households will face extra costs for electric appliances and solar panels. The government’s announcement of <a href="https://www.premier.vic.gov.au/new-victorian-homes-go-all-electric-2024">$10 million</a> for Residential Electrification Grants should help with some of these costs while the industry adjusts. There will be impacts and benefits for the local economy. Some jobs may be lost, particularly in the gas appliance and plumbing industry. The government has announced financial support to retrain people and they will still have essential roles in the existing housing sector. Many gas appliances are imported, including ovens, cooktops and instantaneous gas water heaters. Some components of efficient electric products, such as hot water storage tanks, are made locally. Local activities, including distribution, sales, design, installation and maintenance, comprise much of the overall cost. <h2>Challenges of change must be managed</h2> Sustainability benefits will depend on what <a href="https://grattan.edu.au/report/getting-off-gas/">happens with the energy network</a>. We need more renewable energy, energy storage and smarter management of electricity demand. The shift to all-electric homes may mean winter peak demand for heating increases. Energy market operators and governments will have to monitor demand changes carefully to avoid the reliability issues we already see in summer. However, improving energy efficiency, energy storage and demand management will help reduce this load (and household costs). While the benefits are clear for new homes, the changes may <a href="https://www.bsl.org.au/research/publications/enabling-electrification/">increase gas costs and energy poverty</a> for residents of existing housing who don’t shift to efficient electric solutions. The government has reconfirmed financial rebates to help households switch from gas. In addition, existing housing may face building quality and performance issues. Some may require electrical wiring upgrades as part of the transition. Social acceptance of some electric appliances may also be an issue. For example, <a href="https://www.rmit.edu.au/about/schools-colleges/property-construction-and-project-management/research/research-centres-and-groups/sustainable-building-innovation-laboratory/projects/heet-housing-energy-efficiency-transitions">our research</a> has found some households dislike the way heating from reverse cycle air conditioners feels. Others do not like cooking on induction cooktops. Consumer education and modifications to appliances and buildings may be needed to increase acceptance and avoid backlash. Some electric appliances are available overseas but not in Australia. Higher demand may increase the range of imports. For example, floor-mounted heat pumps can make heating feel similar to gas heating while still providing effective cooling. We should not assume electric appliances are all equal. To improve consumer protection, action is needed on weak standards and limited and inconsistent public information. For example, information on noise levels and efficiency under a range of weather conditions must be standardised. Moving housing away from gas is an <a href="https://link.springer.com/book/10.1007/978-981-99-2760-9">important step</a> in the transition to a zero-carbon economy and energy system. Careful management is needed to ensure this transition is effective, accepted and fair. Continued planning reforms are also essential to ensure environmentally sustainable development of housing and communities. Other urgent priorities include urban cooling and greening, and <a href="https://theconversation.com/turning-the-housing-crisis-around-how-a-circular-economy-can-give-us-affordable-sustainable-homes-208745">circular economy approaches</a> to reduce the material and waste impacts of housing and thus the carbon that goes into building and running homes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210649/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/trivess-moore-12580">Trivess Moore</a>, Senior Lecturer, School of Property, Construction and Project Management, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>; <a href="https://theconversation.com/profiles/alan-pears-52">Alan Pears</a>, Senior Industry Fellow, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a>, and <a href="https://theconversation.com/profiles/joe-hurley-157161">Joe Hurley</a>, Associate Professor, Sustainability and Urban Planning, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tourists flock to the Mediterranean as if the climate crisis isn’t happening. This year’s heat and fire will force change

<a href="https://theconversation.com/profiles/susanne-becken-90437">Susanne Becken</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/johanna-loehr-1457342">Johanna Loehr</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Thousands of people on the beach. Children reportedly falling off evacuation boats. Panic. People fleeing with the clothes on their backs. It felt like “the end of the world”, according to <a href="https://www.theguardian.com/world/2023/jul/23/british-tourists-tell-of-nightmare-in-rhodes-fires-greece">one tourist</a>. The fires sweeping through the Greek islands of Rhodes and Corfu are showing us favourite holiday destinations are no longer safe as climate change intensifies. For decades, tourists have flocked to the Mediterranean for the northern summer. Australians, Scandinavians, Brits, Russians all arrive seeking warmer weather. After COVID, many of us have been keen to travel once again. But this year, the intense heatwaves have claimed <a href="https://inews.co.uk/news/world/heatwave-pictures-wildfires-worsen-greece-italy-spain-europe-us-2488556">hundreds of lives</a> in Spain alone. Major tourist drawcards such as the Acropolis in Athens have been closed. Climate scientists are “stunned by the ferocity” of the <a href="https://www.theguardian.com/commentisfree/2023/jul/25/northern-hemisphere-heatwaves-europe-greece-italy-wildfires-extreme-weather-climate-experts">heat</a>. This year is likely to force a rethink for tourists and for tourism operators. Expect to see more trips taken during shoulder seasons, avoiding the increasingly intense July to August summer. And expect temperate countries to become more popular tourist destinations. Warm-weather tourist destinations will have to radically change. <h2>What will climate change do to mass tourism?</h2> Weather is a major factor in tourism. In Europe and North America, people tend to go from northern countries to southern regions. Chinese tourists, like Australians, often head to Southeast Asian beaches. In Europe, the north-south flow is almost hardwired. When Australians go overseas, they often choose Mediterranean summers. Over the last decade, hotter summers haven’t been a dealbreaker. But this year is likely to drive change. You can already see that in the growing popularity of shoulder seasons (June or September) in the traditional Northern Hemisphere summer destinations. Many of us are shifting how we think about hot weather holidays from something we seek to something we fear. This comes on top of consumer shifts such as those related to sustainability and <a href="https://theconversation.com/flight-shaming-how-to-spread-the-campaign-that-made-swedes-give-up-flying-for-good-133842">flight shame</a>. What about disaster tourism? While thrillseekers <a href="https://www.theguardian.com/us-news/2023/jul/22/death-valley-tourism-extreme-weather-california">may be flocking</a> to Death Valley to experience temperatures over 50℃, it’s hard to imagine this type of tourism going mainstream. What we’re more likely to see is more people seeking “<a href="https://www.tandfonline.com/doi/abs/10.1080/09669582.2016.1213849?journalCode=rsus20">last-chance</a>” experiences, with tourists flocking to highly vulnerable sites such as the Great Barrier Reef. Of course, this type of tourism isn’t sustainable long-term. <h2>What does this mean for countries reliant on tourism?</h2> The crisis in Rhodes shows us the perils of the just-in-time model of tourism, where you bring in tourists and everything they need –food, water, wine – as they need it. The system is geared to efficiency. But that means there’s little space for contingencies. Rhodes wasn’t able to easily evacuate 19,000 tourists. This approach will have to change to a just-in-case approach, as in other <a href="https://www.forbes.com/sites/willyshih/2022/01/30/from-just-in-time-to-just-in-case-is-excess-and-obsolete-next/?sh=195cd054daf7">supply chains</a>. For <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517712002063">emergency services</a>, tourists pose a particular challenge. Locals have a better understanding than tourists of risks and escape routes. Plus tourists don’t speak the language. That makes them much harder to help compared to locals. Climate change poses immense challenges in other ways, too. Pacific atoll nations like Kiribati or Tuvalu <a href="https://www.pacificpsdi.org/assets/Uploads/PSDI-TourismSnapshot-TUV3.pdf">would love</a> more tourists to visit. The problem there is water. Sourcing enough water for locals is getting harder. And tourists use a lot of water – drinking it, showering in it, swimming in it. Careful planning will be required to ensure local carrying capacities are not exceeded by tourism. So does this spell the end of mass tourism? Not entirely. But it will certainly accelerate the trend in countries like Spain away from mass tourism, or “overtourism”. In super-popular tourist destinations like Spain’s Balearic Islands, there’s been an increasing pushback from locals against <a href="https://theconversation.com/were-in-the-era-of-overtourism-but-there-is-a-more-sustainable-way-forward-108906">overtourism</a> in favour of specialised tourism with smaller numbers spread out over the year. Is this year a wake-up call? Yes. The intensifying climate crisis means many of us are now more focused on what we can do to stave off the worst of it by, say, avoiding flights. The pressure for change is growing too. Delta Airlines is being sued over its announcement to go carbon neutral by <a href="https://www.theguardian.com/environment/2023/may/30/delta-air-lines-lawsuit-carbon-neutrality-aoe">using offsets</a>, for instance. <h2>Mountains not beaches: future tourism may look a lot different</h2> You can already see efforts to adapt to the changes in many countries. In Italy, for instance, domestic mountain tourism is <a href="https://www.euromontana.org/en/neve-diversa-how-mountain-tourism-can-adapt-to-climate-change/">growing</a>, enticing people from hot and humid Milan and Rome up where the air is cooler – even if the snow is disappearing. China, which doesn’t do things by halves, is investing in mountain resorts. The goal here is to offer cooler alternatives like northern China’s <a href="https://english.news.cn/20230714/9ae6f89a6b7b433ebde3ec689b87f6db/c.html">Jilin province</a> to beach holidays for sweltering residents of megacities such as Beijing and Shanghai. Some mountainous countries are unlikely to seize the opportunity because they don’t want to draw more tourists. Norway is considering a <a href="https://www.forbes.com/sites/davidnikel/2022/12/03/norway-to-consider-introducing-tourist-tax-from-2024/?sh=710871eb1b27">tourist tax</a>. Forward-thinking countries will be better prepared. But there are limits to preparation and adaptation. Mediterranean summer holidays will be less and less appealing, as the region is a <a href="https://www.unep.org/unepmap/resources/factsheets/climate-change">heating hotspot</a>, warming 20% faster than the world average. Italy and Spain are still <a href="https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/severe-drought-western-mediterranean-faces-low-river-flows-and-crop-yields-earlier-ever-2023-06-13_en">in the grip</a> of a record-breaking drought, threatening food and water supplies. The future of tourism is going to be very different. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210282/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/susanne-becken-90437">Susanne Becken</a>, Professor of Sustainable Tourism, Griffith Institute for Tourism, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/johanna-loehr-1457342">Johanna Loehr</a>, , <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to keep your pets cool in the heat

Now that the weather is warm, extra precautions in the sun are necessary not just for yourself, but for your furry companion. Try these useful tips to help keep Fido and Fluffy safe and cool in the heat all summer long. Give them a trim – If your pet has long hair, consider grooming them seasonally, as shorter hair makes a big difference in their overall temperature. Keep water handy – If you leave the house with your pet, always be sure to have water on you as well as a receptacle from which they can drink to keep your pet cool and hydrated. You can even set up a kiddy pool in your backyard for your dog to play in. Look for shade – If you’re out with your dog midday, try to avoid direct sunlight by locating a shady area for a rest. Follow their lead – If you dog or cat seems most content to stay indoors and enjoy the air conditioning, let them. They can tell if it’s too hot outside for them. Time it right – Avoid going out midday when possible, and take your dog for walks during the mornings and evenings instead. Never leave them in the car – Many animals die every year because irresponsible owners leave them in a car, leading to over-heating. Even if the day seems moderate in temperature, a car can still heat up drastically due to solar heat beaming in through the windows. If you’ll be leaving your car alone, leave your pet at home. Act according to breed – If your pet has a flat-shaped face, such as a pug or Persian cat, they are especially susceptible to the heat as they are unable to cool down through panting as effectively as other breeds can. If in doubt, bring them inside where it is cooler. Image credit: Shutterstock

Stop your makeup melting in the heat

Party season and soaring temperatures mean one thing – melting makeup! Make sure you don’t end up looking like Alice Cooper this summer with our guide to a face that stays put even when the mercury rises. Blank canvas Exfoliate so that your face is ultra-smooth and products will stay on evenly, rather than migrating to one particularly dry area. After your usual moisturizer, make sure you apply SPF30+ or SPF50+ sunscreen. After all, there’s no point in going to all this trouble if you’re just going to end up looking like a tomato anyway! Then use a primer to take away shine. Another layer might seem counter-productive, but you can imagine what happens to make-up that’s applied to a slippery surface. Dare to bare Too much powder and sweat aren’t a good mix, literally. Powders can clog and looked caked when we start to ‘glow’ on scorching days. Similarly, long-lasting foundations can be too heavy and textured and look too much like make-up. Instead, opt for a light coverage foundation or illuminating tinted moisturiser to keep your look sheer and natural. Cheeks Using a brush, apply a cream blush to the apples of your cheeks. The beauty of a cream blush is that if it starts to budge, you can just blend it back in with your finger. Go easy on the bronzer. Use a shade that’s just one shade darker than your natural skin tone and apply it only where the sun would naturally catch your face. Eye Smokey eyes soon become raccoon eyes in the heat, so keep the natural look going with a creamy, slightly shimmery eye shadow in a coppery shade. Stick-style shadows stay in place very well and are easy to reapply on-the-go. Liquid eyeliner is best avoided in the heat. Use a pencil or at least a waterproof formulation. To avoid your eyebrows melting, go for a light pencil rather than a wax, then finish your eyes with waterproof mascara. Lips Thick gloss can feel a bit gloopy when the temperatures soar, and a heavy lipstick will overwhelm the natural look on your eyes and cheeks. Try a light chubby-stick style lip stain or a tinted lip balm with SPF in it to provide sheer colour and sun protection in one. Staying power It’s really important to ‘set’ your face after you’ve applied it, but it’s a fine line between setting it and adding powder that’s just going to cake. Use a good quality translucent powder just on your T-zone. A little goes a long way so dab it on the back of your hand first, then apply from there. Finally, keep some blotting papers in your handbag. Blotting papers don’t just mattify shine- they actually soak up excess oil and sweat, so they’re perfect for hot days! Image credits: Getty Images

A heated steering wheel for $20 a month? What’s driving the subscriptions economy

From gym memberships to music and movies, to razors, toilet paper, meal kits and clothes, there’s seemingly no place the subscription economy can’t go. Having conquered the software market – where it gets its own acronym, SaaS (Software as a Service) – the subscription model is now moving into hardware. Car makers are among the first cabs off the rank, using software to turn on and off optional extras. German auto maker BMW is offering “<a href="https://www.theverge.com/2022/7/12/23204950/bmw-subscriptions-microtransactions-heated-seats-feature" target="_blank" rel="noopener">in-car microtransactions</a>” to access options for car buyers in Britain, Korea, Germany, New Zealand and South Africa. A heated steering wheel, for example, has a monthly cost of NZ$20 in New Zealand, and £10 in the UK. Other markets <a href="https://www.drive.com.au/news/bmw-australia-monthly-subscriptions-detailed/" target="_blank" rel="noopener">including Australia</a> will soon follow. In the UK, seven of 13 “digital services” – from heated seats to automatic high beam and driving assistance – are now available in subscription form. “Welcome to microtransaction hell” is how <a href="https://www.pcgamer.com/welcome-to-microtransaction-hell-buy-a-bmw-pay-monthly-for-the-cars-features/" target="_blank" rel="noopener">one headline</a> put it. But that’s probably overselling the onset of a corporate dystopia where “you will own nothing”. BMW’s motives are pretty straightforward – as is most of what’s driving the subscription economy. What is the subscription model? The subscription model means paying a fee for periodical access to a service or product. Until a decade or so ago, it was largely confined to a few select industries, such as the delivery of milk, newspapers and magazines. <figure class="align-center "><img src="https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/474494/original/file-20220718-68552-hvzp5p.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="From milk and magazines, subscription services have proliferated with digital technology." /><figcaption>From milk and magazines, subscription services have proliferated with digital technology. Shutterstock</figcaption></figure> Other business models had similarities – such as rental businesses – but the point of the subscription model was different. It was not about meeting a demand for a service someone only wanted to use temporarily or could not afford to own outright. It was about locking in a continuing relationship, to maximise “customer lifetime value”. As <a href="https://www.investopedia.com/ask/answers/042715/how-do-subscription-business-models-work.asp" target="_blank" rel="noopener">Investopedia puts it</a>, the subscription model’s focus is on customer retention over customer acquisition: <blockquote> In essence, subscription business models focus on the way revenue is made so that a single customer pays multiple payments for prolonged access to a good or service instead of a large upfront one-time price. </blockquote> This in large part explains why subscription services are now being adopted in markets outside their more obvious fit for things such as streaming news and entertainment. In a broad sense, consumers can now be divided into two groups. One group comprises the “transactional shopper”, who interacts with the vendor once or twice, then disappears. The other group comprises customers whose connection and “investment” in the brand is maintained through their subscriptions. <figure class="align-center "><img src="https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/474211/original/file-20220715-24-eopgdo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="The subscriptions model emphasises customer retention over customer acquisition." /><figcaption>The subscriptions model emphasises customer retention over customer acquisition. Shutterstock</figcaption></figure> E-commerce and access Part of the growth in the subscription economy has come from companies riding the e-commerce wave, delivering goods such as meal kits, wine, coffee, baby supplies, pet food, cleaning products, razors and toilet paper. Consultant firm McKinsey has estimated the subscription e-commerce market is <a href="https://www.mckinsey.com/industries/technology-media-and-telecommunications/our-insights/thinking-inside-the-subscription-box-new-research-on-ecommerce-consumers" target="_blank" rel="noopener">doubling in value</a> every year – though that was before the pandemic. It could be well be more now. The other part of the market is represented by BMW’s approach, offering extra features to customers that can only be accessed for a fee. In some cases this may involve standard “upsell” techniques. For example, when you buy a new Peloton exercise bike you’ll be enticed with <a href="https://www.onepeloton.com.au/membership" target="_blank" rel="noopener">subscription offers</a>, such as virtual classes and “customised” training programs, to “reach your goals”. Or increasingly, as with BMW’s heated seats and steering wheels, it can be done with software turning actual bits of hardware on or off. What is BMW’s game? Is BMW’s purpose to gouge its customers for more money through getting them to pay an ongoing fee for something instead of owning it outright? This is not what its subscription structure indicates. The opposite, in fact. Customers can still buy these options outright. A heated steering wheel in the UK, for example, costs <a href="https://www.bmw.co.uk/en/shop/ls/dp/Steering_Wheel_Heating_SFA_gb" target="_blank" rel="noopener">£200</a>, and in New Zealand <a href="https://www.bmw.co.nz/en/shop/ls/dp/Steering_Wheel_Heating_SFA_nz" target="_blank" rel="noopener">NZ$350</a>. But now they can also pay a subscription – for three years (£150, NZ$250), annually (£100, NZ$250) or monthly (£10, NZ$20). These prices represent a strong signal – that the cost of outright ownership is the most economical. It’s unlikely BMW expects anyone to sign up for the annual or three-yearly options. These are probably just to make the outright cost look more attractive. The monthly offering, on the other hand, may lure owners to try out a feature they would otherwise have rejected buying outright at the time of purchase. Indeed, car makers argue the reason they offer so many options as extras is because most owners don’t want them. So this mostly looks like BMW offering a “try before you buy” option. The pitfalls of over-subscribing That said, companies don’t need to have sinister motives for us to have concerns about the spread of the subscription model. The more things we pay for with “micro-payments”, the harder it becomes to keep track of payments. Many of us continue to pay for products and services we don’t use. A survey of 1,000 Australian adults in 2021, for example, found about a third wasted money on unused subscriptions or memberships – losing an average of about <a href="https://www.savings.com.au/savings-accounts/unused-lockdown-subscriptions-are-costing-aussies-200-a-year" target="_blank" rel="noopener">A$200 a year</a>. Deep psychological associations can influence these decisions. Experiments by US marketing professors Jennifer Savary and Ravi Dhar suggests people with lower “<a href="https://academic.oup.com/jcr/article-abstract/46/5/887/5498871" target="_blank" rel="noopener">self-concept</a>” are less likely to sign up for subscriptions – but also less likely to cancel subscriptions they are not using. We may see the subscription model increasingly used in other sectors – including the health and justice systems. For example, a subscription payment may provide a better level of nutritious food for a resident in an aged care facility, or a hospital or even a prison. This is not dissimilar to the way private health insurance premiums are managed, but still presents important justice and equity concerns. So while there’s no reason to exaggerate the dangers of the subscription economy, it’s also prudent for consumers, advocacy groups and governments to ask “What next?”.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/186913/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/louise-grimmer-212082" target="_blank" rel="noopener">Louise Grimmer</a>, Senior Lecturer in Retail Marketing and Associate Head Research Performance, <a href="https://theconversation.com/institutions/university-of-tasmania-888" target="_blank" rel="noopener">University of Tasmania</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

Heat yourself, not your house: how to survive winter with a 15℃ indoor temperature

How high should you put the heating up over winter? If you don’t mind the bills and ecological impact, you have the encouragement of the World Health Organization to keep the house warm. They recommend an indoor temperature of <a href="https://apps.who.int/iris/bitstream/handle/10665/275839/WHO-CED-PHE-18.03-eng.pdf" target="_blank" rel="noopener">at least 18°</a>, declaring that you face health risks at lower temperatures. This advice is echoed by the <a href="https://www.energy.gov.au/households/household-guides/seasonal-advice/winter" target="_blank" rel="noopener">Australian government</a>. The tone of <a href="https://www.ncbi.nlm.nih.gov/books/NBK535294" target="_blank" rel="noopener">some reports</a> is monitory and severe. Based on these instructions, anyone would feel a reflex to bump up the thermostat. But before you brace for the bill-shock amid soaring energy prices, consider a different approach. Some people cope positively with the freeze and others face deep winter with panic. Given the range of psychological responses, I can only imagine there would be a difference in how people’s health would fare. If I’m full of dread at the prospect of feeling chilly, this stress could aggravate existing health issues. It is entirely possible to avoid heating your entire house to 18℃ to stay warm. If you view your cold house as a project, you can take pleasure in the power of staying warm in your modern cave, while remembering that we evolved to withstand the cold with fewer options than we have today. Staying warm in a cold house Over the last couple of winters, I’ve discovered many strategies for comfortable living at lower room temperatures. To add to traditional methods such as multiple layers of clothing and physical activity, there are now excellent appliances to fend off the chill. Personal heating devices have become rightly popular, such as electrical heated throw rugs to <a href="https://www.jstor.org/stable/90022948" target="_blank" rel="noopener">warm your clothing</a> rather than ambient air. These new devices – think a more flexible electric blanket – are extremely efficient. Canberra energy efficiency enthusiast David Southgate found using these devices rather than heating the air <a href="https://southgateaviation.files.wordpress.com/2020/02/2019-annual-report-v2.pdf" target="_blank" rel="noopener">cut his heating bill</a> by 95%. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=401&fit=crop&dpr=1 600w, https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=401&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=401&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/472222/original/file-20220704-18-sz6rcn.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="electric throw" /></a><figcaption>Electric throw rugs and other personal heating devices are gaining popularity. Shutterstock</figcaption></figure> Personally, I have found adequate clothing makes a temperature of 15℃ acceptable. In fact, dressing warmly poses more risk of overheating with low levels of activity. It’s satisfying to create your own warmth rather than rely on artificially supplied warmth. You start to notice thermodynamic properties of clothing that you’d never appreciate by relying on a thermostat. If you wear a hooded gown, you’ll find not only that your ears are warm from being covered, but your uncovered face becomes flushed. That’s because warmth generated by your body wafts upward to escape through the aperture of the hood. As a result, the air that you breathe is also warm. When it comes to clothing, we can equate warmth simply with insulation. In turn, we assess the insulating qualities of textiles with their thickness or <a href="https://www.abc.net.au/everyday/warmest-materials-fabrics-winter-clothing/101155486" target="_blank" rel="noopener">air-trapping abilities</a>. We often tend to overlook the design of the clothing, which plays a key role in funnelling body warmth to exposed skin. The archetype of the hood was known two millennia before thermostats in both Greece (the garments μαφόρτης and κάλυμμα) and Rome (the garments cucullus, lacerna and tunica palliolata). They’re just as effective today. Wearing a cowl won’t warm up your hands; but if the rest of you is warm – especially your feet – your exposed hands will benefit by the circulation. For anyone unconvinced by this assurance, fingerless gloves are a backstop. The way medical science has catastrophised indoor temperatures lower than 18℃ wouldn’t be so bad if it were only incurious and unimaginative. Alas, there are alarming ecological consequences of a population believing that they’ll automatically get sick in the cold. Carbon emissions from domestic heating are significant. You get a picture from gas bills in Queensland, which go up 1.4 times from summer to winter. In colder states, the figure is <a href="https://www.energycouncil.com.au/analysis/winter-energy-bills-avoid-a-shock" target="_blank" rel="noopener">much higher</a>: 3.5 times in Victoria and 5.2 times in nippy Tasmania. We have to scrutinise if we really need our thermostats pegged at 18℃. Before we accept recommendations on indoor temperatures by medical authorities, we need to know if the science has grappled with different experiences of cold. Future research must distinguish between people in a cool room who feel cold and miserable or feel protected against cold by a range of practical measures. Understanding the effect of these variables is urgent, because current authoritative guidance pushes us into heating our houses more than we have to. For most of the world, that means burning fossil fuel.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/185587/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/robert-nelson-1355694" target="_blank" rel="noopener">Robert Nelson</a>, Honorary Principal Fellow, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722" target="_blank" rel="noopener">The University of Melbourne</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

Prince George complains about sweltering Wimbledon heat

A video of Prince George has emerged, as the young royal was spotted complaining to his father that he was "too hot" in his suit at Wimbledon. The 8-year-old was the perfect prince as he attended the men's final match with his parents, but with soaring summer temperatures hitting 28 degrees, he found himself struggling in his suit and tie. After hugging Prince William, the young prince initially said he was feeling "ok" but then complained about the temperature as he walked along with his parents. Fans on social media also expressed concern about the youngster being too warm, and Royal Editor Robert Jobson tweeted that while William and Kate were being respectful of the All England Club's formal dress code, nobody would have minded George wearing something less formal. As Prince William and Kate Middleton greeted Wimbledon officials, George was seen saying "it's too hot" to his parents. Kate then advised her son he needed to avoid sitting "in the bright sunshine" and added they are "often in the shade". Photos showed doting father William checking in on his son while he tried to cool himself down, as some viewers took to Twitter to express their concern for the young prince in his suit. One person wrote, "Why do they dress him in a suit and tie and in this heat." Another said, "Poor Prince George in a shirt, tie and jacket in that stifling heat." The young royal then beamed as he shook hands with servicemen and women before the match, and sat watching the men's final like a perfect gentlemen. Serbian tennis champ Novak Djokovic defeated Aussie Nick Kyrgios in the match, as he reigned in his seventh victory at Wimbledon. Image credits: Getty Images

"Paid off my mortgage" party sparks heated online debate

A heated online debate has been sparked after a woman has been left questioning whether or not she should attend a friends party celebratory “paid off her mortgage” party. The unnamed woman took to the British parenting forum ‘Mumsnet’ to reveal that one of her close friends, who allegedly had help from her family, is celebrating paying off her mortgage. She revealed she “doesn't want to begrudge anyone” but the party “feels a bit fake” to her. She was met with mixed reactions as some agreed that it looks “crass” and “lacks self awareness”, especially during the ongoing global cost of living and housing crisis. However, others made the point that some people want to celebrate milestones that are not linked back to traditional family set ups for example: weddings, christenings and children's birthdays. The mother explained: “A friend of mine is having a party to celebrate paying her mortgage off, I don't begrudge anyone paying off their mortgage as it's a fantastic achievement, but she has had sooo much help from her family etc..” “She's been gifted at least £300,000 over the life of her mortgage. How would you feel about attending such a party ?? It feels a bit fake to me. She went on to say "My husband laughed his socks off when I told him about the party invite he said "Bank of Mum and Dad" paid mortgage off.” One Mumsnet user replied: “I think it's probably an "any excuse for a party" sort of thing - but it's a bit crass/tactless/lacking in self awareness”. However, others thought it was no more “crass” than “any other celebration.” Another valid point made by some users was people celebrate birthdays and their baby's gender reveals so why not celebrate being mortgage free.

3 surprise benefits of heated towel racks in summer

During the colder months, nothing beats stepping out of the shower and pulling a freshly warmed towel off the rack. But, heated towel racks are useful beyond chilly winter mornings. Here are <a rel="noopener" href="https://www.bhg.com.au/heated-towel-rack-summer" target="_blank">three reasons</a> they can be just as useful during humid summer months too. 1. Beat the humidity Though using a heated towel rack in summer sounds pointless, the racks actually work to dry rather than warm towels - a godsend when high humidity strikes. Drying your towel in humidity can be difficult when it’s still damp from the previous day, that extra bit of drying power can ensure your towel is ready to use when you hit the shower again. Some towel racks also come with temperature control, meaning you can lower the temperature on hot days and still enjoy your freshly dried towels. 2. Save on your energy bill and water use According to Bathroom Butler Australia, a producer of heated towel racks, towels dried on a rack don’t require washing as regularly as air-dried towels. As a result, you can both save hours on doing laundry and reduce how much water you use. Plus, heated towel racks can be used to dry more than just towels and can help you cut down on using the dryer for clothing items such as swimmers and underwear. 3. Stop mould in its tracks Hot showers produce a surprising amount of moisture that even bathroom fans can’t quite combat effectively, leading to mould. Unfortunately, damp fabrics stored in the bathroom - such as towels - aren’t as safe from mould as we might think. Unless your bathroom is well-ventilated, using a heated towel rack can ensure your towels stay mould-free. Image: Getty Images

How hot is too hot? Here’s how to tell if your dog is suffering during the summer heat

Hot weather can be dangerous to our canine friends. Humans can sweat all over our body, but dogs can only sweat on their paw pads, which is not much use when it comes to shedding body heat. So how hot is too hot to take your dog out? It depends on the dog and their individual risk factors (more on that in a minute). For me, 33℃ is where I start to consider whether or not to take my dogs outside, and try to think of cooler places we could visit. If they were older or heavier, I might not take them out at all on days over 30℃. Dogs can struggle on very humid days so I factor that in, too. Here’s what you need to know about how to care for your dog on a hot day. <a href="https://images.theconversation.com/files/437053/original/file-20211212-23-1o3loh4.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437053/original/file-20211212-23-1o3loh4.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="spoodle dog" /></a> Dogs with long noses, like Fonzi, have more cooling structures. Lucy Beaumont, <a href="http://creativecommons.org/licenses/by/4.0/" class="license">CC BY</a> <h2>What are the risk factors?</h2> A dog’s main cooling mechanism is panting, which draws air through the nasal cavity and the mouth and over the capillaries found there. This allows for evaporative cooling, just as sweat on our skin does, but it happens inside rather than outside. It’s also a much smaller surface area than our skin, so dogs are generally not as good at shedding body heat as humans. If the dog is overweight, they may have more trouble keeping cool than if they are lean. A dog with underlying health issues such as heart problems may also be at greater risk. Very young or old dogs may have more trouble with temperature regulation. Dogs that have had a chance to get used to warmer temperatures over a month or so are less susceptible to heat distress. Because some cooling occurs in the nasal cavities, dogs with short faces have fewer of these cooling structures and are more susceptible to heat distress. Dogs with long noses have more surface area for cooling in their nasal cavities, and are theoretically more resistant to heat distress as a result. But much depends on the individual dog and its history. <a href="https://images.theconversation.com/files/437054/original/file-20211212-13-1lcms43.JPG?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437054/original/file-20211212-13-1lcms43.JPG?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="labradoodle" /></a> Dogs with thick coats, like Stella, may struggle to shed heat on a hot day. Lucy Beaumont, <a href="http://creativecommons.org/licenses/by/4.0/" class="license">CC BY</a> <h2>Your dog’s coat plays a role but should we shave them?</h2> Larger or heavier-bodied dogs generally shed heat more slowly than smaller dogs, as is the case across the animal kingdom. For example, smaller penguin species tend to visit warmer climates, while larger penguin species stay in colder climates. <a href="https://images.theconversation.com/files/437114/original/file-20211213-15-wxuu3h.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437114/original/file-20211213-15-wxuu3h.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="" /></a> Dogs from cooler climes – like Kivi Tarro, a Finnish lapphundtend – to have heavy, insulating coats while those from warmer places tend to have thin hair. Melissa Starling, Author provided Dogs from cooler climes tend to have heavy, insulating coats while those from warmer places tend to have thin hair, which helps shed heat quickly. So, would your dog be cooler if you shaved them for summer? It’s true insulation works both ways; cold or hot air outside the body cannot easily penetrate a thick coat and affect core temperature. But a dog is always producing body heat, especially when they are active or excited, and this internal heat may escape slowly through a thick coat. <a href="https://images.theconversation.com/files/437113/original/file-20211213-13-1xxwrzi.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437113/original/file-20211213-13-1xxwrzi.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="" /></a> Kivi Tarro, a Finnish lapphund, shows off his haircut. Melissa Starling, Author provided For many thick-coated, otherwise healthy dogs, it helps to keep their coat free of tangles and dead undercoat during warmer months. This reduces the insulating properties of the coat. Clipping the coat shorter can allow them to stay cool more easily. You could also consider clipping the belly and groin very short. This won’t help much when the dog is active but could help when the dog lies on a cool surface. However, be mindful not to go too short on upper parts of the coat, or the skin can be exposed to sunburn. <h2>How to ‘ask your dog’ how they’re doing</h2> We should always “ask the dog” how they are doing. Signs a dog is too hot include: <ul> <li> panting a lot during the warmer months, even when not exercising </li> <li> seeming lethargic and reluctant to exercise </li> <li> regularly seeking to cool themselves by getting wet, or lying on cool tile or wood floors with as much skin contact as possible. </li> </ul> Always consider the following rules of thumb: <ul> <li> if it’s too hot for you, it’s probably too hot for your dog </li> <li> make sure water is available for drinking or immersing the body in when exercising on hot days </li> <li> know your dog’s panting. Dogs usually have a pant cycle where they pant for a short period and then stop for a few breaths or more and then start again. If they start panting constantly, they may be struggling to cool themselves </li> <li> if they can’t hold a ball or toy anymore, froth at the mouth because they can’t easily swallow, or have trouble drinking due to panting at the same time, get your dog to some shade and let them rest. Monitor for signs of heat stress </li> <li> signs of extreme heat distress include: vomiting, diarrhoea, lethargy, being unsteady on their feet, or limping. Take your dog to the vet immediately if you see these signs. Heat injury can be lethal! </li> <li> pick shady, cool places to let your dog have a run if it’s warm. Go early or late in the day when the temperature has come down a bit. Early mornings are typically cooler than the late afternoon </li> <li> the lack of airflow in cars can turn them into deadly ovens within a few minutes, even if the windows are down. So never leave your dog alone in a car, even for a few minutes.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/172957/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, Postdoctoral researcher, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A new approach finds materials that can turn waste heat into electricity

The need to transition to clean energy is apparent, urgent and inescapable. We must limit Earth’s rising temperature to within 1.5 C to avoid the worst effects of climate change — an especially daunting challenge in the face of the steadily increasing global demand for energy. Part of the answer is using energy more efficiently. <a href="https://doi.org/10.1016/j.rser.2015.12.192">More than 72 per cent of all energy produced worldwide is lost in the form of heat</a>. For example, <a href="https://doi.org/10.1007/s11664-011-1580-6">the engine in a car uses only about 30 per cent of the gasoline it burns to move the car</a>. The remainder is dissipated as heat. Recovering even a tiny fraction of that lost energy would have a tremendous impact on climate change. Thermoelectric materials, which convert wasted heat into useful electricity, can help. Until recently, the identification of these materials had been slow. My colleagues and I have used quantum computations — a computer-based modelling approach to predict materials’ properties — to speed up that process and identify more than 500 thermoelectric materials that could convert excess heat to electricity, and help improve energy efficiency. <h2>Making great strides towards broad applications</h2> The transformation of heat into electrical energy by thermoelectric materials is based on the “Seebeck effect.” In 1826, German physicist <a href="https://doi.org/10.1002/andp.18260820302">Thomas Johann Seebeck observed that exposing the ends of joined pieces of dissimilar metals to different temperatures generated a magnetic field</a>, which was later recognized to be caused by an electric current. Shortly after his discovery, <a href="http://dx.doi.org/10.1049/jste-1.1875.0018">metallic thermoelectric generators were fabricated to convert heat from gas burners into an electric current</a>. But, as it turned out, <a href="https://www.electronics-cooling.com/2006/11/the-seebeck-coefficient/">metals exhibit only a low Seebeck effect</a> — they are not very efficient at converting heat into electricity. <a href="https://images.theconversation.com/files/437873/original/file-20211215-19-1nq0m8v.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/437873/original/file-20211215-19-1nq0m8v.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="A black and white photo of a woman turning a dial on a large table top radio, with a lantern hanging above it." /></a> The kerosene radio was designed for rural areas, and was powered by the kerosene lamp hanging above it. The flame created a temperature difference across metals to generate the electrical current. ('Popular Science', Issue 6, 1956) In 1929, the Russian scientist <a href="https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/ioffe-abram-fedorovich">Abraham Ioffe</a> revolutionized the field of thermoelectricity. He observed that semiconductors — materials whose ability to conduct electricity falls between that of metals (like copper) and insulators (like glass) — exhibit a significantly higher Seebeck effect than metals, boosting thermoelectric efficiency 40-fold, <a href="https://www.kelk.co.jp/english/useful/netsuden3.html">from 0.1 per cent to four per cent</a>. This discovery led to the development of the first widely used thermoelectric generator, <a href="https://swling.com/blog/2020/05/soviet-era-kerosene-lamp-generator-gives-new-meaning-to-lets-fire-up-the-radio/">the Russian lamp</a> — a kerosene lamp that heated a thermoelectric material to power a radio. <h2>Are we there yet?</h2> Today, thermoelectric applications range from energy generation in <a href="https://www.energy.gov/ne/articles/what-radioisotope-power-system">space probes</a> to <a href="https://www.newair.com/blogs/learn/what-is-thermoelectric-cooling-and-is-it-right-for-you">cooling devices in portable refrigerators</a>. For example, space explorations are powered by radioisotope thermoelectric generators, <a href="https://solarsystem.nasa.gov/missions/cassini/radioisotope-thermoelectric-generator/">converting the heat from naturally decaying plutonium into electricity</a>. In the movie The Martian, for example, a box of plutonium saved the life of the character played by Matt Damon, by keeping him warm on Mars. <iframe width="440" height="260" src="https://www.youtube.com/embed/0CvzBu5sTps?wmode=transparent&start=0" frameborder="0" allowfullscreen=""></iframe> In the 2015 film, The Martian, astronaut Mark Watney (Matt Damon) digs up a buried thermoelectric generator to use the power source as a heater. Despite this vast diversity of applications, wide-scale commercialization of thermoelectric materials is still limited by their low efficiency. What’s holding them back? Two key factors must be considered: the conductive properties of the materials, and their ability to maintain a temperature difference, which makes it possible to generate electricity. The best thermoelectric material would have the electronic properties of semiconductors and the poor heat conduction of glass. But this unique combination of properties is not found in naturally occurring materials. We have to engineer them. <h2>Searching for a needle in a haystack</h2> In the past decade, new strategies to engineer thermoelectric materials have emerged due to an enhanced understanding of their underlying physics. In a <a href="https://doi.org/10.1038/s41563-021-01064-6">recent study in Nature Materials</a>, researchers from Seoul National University, Aachen University and Northwestern University reported they had engineered a material called tin selenide with the highest thermoelectric performance to date, nearly twice that of 20 years ago. But it took them nearly a decade to optimize it. To speed up the discovery process, my colleagues and I have used quantum calculations to search for new thermoelectric candidates with high efficiencies. We searched a database containing thousands of materials to look for those that would have high electronic qualities and low levels of heat conduction, based on their chemical and physical properties. These insights helped us find the best materials to synthesize and test, and calculate their thermoelectric efficiency. We are almost at the point where thermoelectric materials can be widely applied, but first we need to develop much more efficient materials. With so many possibilities and variables, finding the way forward is like searching for a tiny needle in an enormous haystack. Just as a metal detector can zero in on a needle in a haystack, quantum computations can accelerate the discovery of efficient thermoelectric materials. Such calculations can accurately predict electron and heat conduction (including the Seebeck effect) for thousands of materials and <a href="https://doi.org/10.1039/D0MH01112F">unveil the previously hidden and highly complex interactions between those properties</a>, which can influence a material’s efficiency. Large-scale applications will require themoelectric materials that are inexpensive, non-toxic and abundant. Lead and tellurium are found in today’s thermoelectric materials, but their cost and negative environmental impact make them good targets for replacement. Quantum calculations can be applied in a way to search for specific sets of materials using parameters such as scarcity, cost and efficiency. Although those calculations can reveal optimum thermoelectric materials, synthesizing the materials with the desired properties remains a challenge. A multi-institutional effort involving government-run laboratories and universities in the United States, Canada and Europe has revealed more than <a href="https://doi.org/10.1039/C5TC01440A">500 previously unexplored materials</a> with high predicted thermoelectric efficiency. My colleagues and I are currently investigating the thermoelectric performance of those materials in experiments, and have already discovered new sources of high thermoelectric efficiency. Those initial results strongly suggest that further quantum computations can pinpoint the most efficient combinations of materials to make clean energy from wasted heat and the avert the catastrophe that looms over our planet.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/173472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jan-hendrik-pohls-1289084">Jan-Hendrik Pöhls</a>, McCall MacBain Postdoctoral Fellow, Department of Chemistry and Chemical Biology, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Extreme heat increases health risk for everyone

<div class="copy"> Extreme heat is a <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/understanding-killer-heat/" target="_blank">killer</a>. It’s responsible for thousands of deaths around the world every year, with a huge proportion of those already <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/climate-change-causes-one-third-of-heat-related-deaths/" target="_blank">attributed to rising global temperatures</a>. Studies have long shown that people over the age of 65 face an increased risk of hospital admission and death during extreme heat days, but US and Canadian researchers have now found that young and middle-aged people are at risk, too. “By looking at emergency department visits for different causes and for several age groups, we were able to characterise with accuracy the varying impact on health on different populations,” says study co-author Francesca Dominici, from the Harvard T.H. Chan School of Public Health. “An important goal of this study is to provide actionable information to clinicians and public health experts regarding how to prevent these emergency department visits, also considering that we can anticipate when these extreme heat events are likely to occur.” Published in the BMJ, <a rel="noreferrer noopener" href="https://dx.doi.org/10.1136/BMJ-2021-065653" target="_blank">the study</a> found that extremely hot days – with an average temperature of 34.4°C – are associated with a higher risk of emergency department (ED) presentation for adults of all ages. The strongest association was for adults between the ages of 18 and 64. The study was large, spanning more than 74 million adults and 22 million ED visits across 2939 US counties during the months of May to September from 2010 to 2019. It used medical insurance claims data to investigate links between hot days and rates of ED visits for any cause as well as specific causes (namely heat-related illness, kidney disease, cardiovascular disease, respiratory disease and mental disorders). Extreme heat days increased people’s risk of an ED visit by 66% for a heat-related illness, as well as by 30% for renal disease. But the risk varied with age – there was a 10.3% higher risk of ED visits in people ages 45 to 54 years old, compared to a 3.6% higher risk in those older than 75. “Younger adults may be at greater risk of exposure to extreme heat, particularly among workers that spend substantial time outdoors,” says lead author Shengzhi Sun, from the Department of Environmental Health at Boston University School of Public Health (BUSPH). “Younger adults may also not realise that they too can be at risk on days of extreme heat.” Gregory Wellenius, professor of environmental health at BUSPH, says the researchers chose to look at ED visits instead of hospital admissions for a reason. “Many illnesses that lead to utilisation of the emergency department do not lead to hospitalisation because they can be treated in a short amount of time, particularly among the younger adult population,” he explains. “By looking at emergency room visits, we aimed to obtain a more comprehensive picture of the true burden of disease that might be attributed to the days of high heat.” The study also found differences in risk across regions – there was a higher risk of ED visits on extreme heat days in the US’s northwest, midwest and northwest, as opposed to the hotter southeast. The researchers say this shows heat is especially dangerous in cooler climates, where people may be less adapted to, or less aware of, heat. This is crucial to recognise as global temperatures rise, particularly as countries, states and regions are deciding how to adapt. “Although climate change is a global problem and heat threatens the health of everybody across the world, the impacts are felt locally, and the solutions have to be tailored to local needs,” says Wellenius. “What works for heatwave preparedness in the Pacific Northwest is really different from what works in the southeastern US, so the solutions have to be localised to accommodate the needs of the local community.” Extreme heat is a particular problem in cities. Exposure to deadly urban heat has <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/scorching-cities-deadly-urban-heat-has-tripled/" target="_blank">tripled</a> since the 1980s, and with more than 50% of the world’s population currently living in urban areas, this signals an urgent need to <a rel="noreferrer noopener" href="https://cosmosmagazine.com/cosmos-briefing/cities-of-the-future/" target="_blank">redesign our future cities</a> to keep us healthy as the world warms.

Deforestation can raise local temperatures by up to 4.5℃ – and heat untouched areas 6km away

Forests directly cool the planet, like natural evaporative air conditioners. So what happens when you cut them down? In tropical countries such as Indonesia, Brazil and the Congo, rapid deforestation <a href="https://www.nature.com/articles/nclimate3250">may have accounted for</a> up to 75% of the observed surface warming between 1950 and 2010. <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac2fdc">Our new research</a> took a closer look at this phenomenon. Using satellite data over Indonesia, Malaysia and Papua New Guinea, we found deforestation can heat a local area by as much as 4.5℃, and can even raise temperatures in undisturbed forests up to 6km away. More than 40% of the world’s population live in the tropics and, under climate change, rising heat and humidity could push them into <a href="https://www.nature.com/articles/s41561-021-00695-3">lethal conditions</a>. Keeping forests intact is vital to protect those who live in and around them as the planet warms. <a href="https://images.theconversation.com/files/431859/original/file-20211115-13-g3akke.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/431859/original/file-20211115-13-g3akke.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /></a> Trees provide shade, habitat, and regulate the supply of clean water. Shutterstock <h2>Deforestation hot spots</h2> At the recent climate change summit in Glasgow, world leaders representing 85% of Earth’s remaining forests committed to ending, and reversing, <a href="https://ukcop26.org/glasgow-leaders-declaration-on-forests-and-land-use/">deforestation by 2030</a>. This is a crucial measure in our fight to stop the planet warming beyond the internationally agreed limit of 1.5℃, because forests store vast amounts of carbon. Deforestation releases this carbon – <a href="https://royalsocietypublishing.org/doi/full/10.1098/rstb.2019.0120">approximately 5.2</a> billion tonnes of carbon dioxide per year – back into the atmosphere. This accounts for nearly 10% of the global emissions from 2009-2016. Deforestation is <a href="https://www.science.org/doi/10.1126/sciadv.aax8574">particularly prevalent</a> in Southeast Asia. <a href="https://data.globalforestwatch.org/documents/14228e6347c44f5691572169e9e107ad/explore">We calculate</a> that between 2000 and 2019, Indonesia lost 17% of its forested area (26.8 million hectares of land), and Malaysia 28% of its forest cover (8.12 million hectares). Others in the region, such as Papua New Guinea, are considered “<a href="https://wwf.panda.org/discover/our_focus/forests_practice/deforestation_fronts_/">deforestation hot spots</a>”, as they’re at high risk of losing their forest cover in the coming decade. Forests in this region are cut down for a variety of reasons, including for expanding palm oil and timber plantations, logging, mining and small-scale farms. And these new types of land uses produce different spatial patterns of forest loss, which we can see and measure using satellites. <h2>What we found</h2> We already know forests cool the climate directly, and losing forest causes local temperatures to rise. But we wanted to learn whether the different patterns of forest loss influenced how much temperatures increased by, and how far warming spread from the deforested site into neighbouring, unchanged areas. To find out, <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac2fdc">we used</a> satellite images that measure the temperature of the land surface. As the illustration below shows, we measured this by averaging forest loss in rings of different widths and radius, and looking at the average temperature change of the forest inside the ring. <a href="https://images.theconversation.com/files/431019/original/file-20211109-27-mpcx2l.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/431019/original/file-20211109-27-mpcx2l.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Illustration of how temperature changes due to forest loss." /></a> How forest clearing near an unchanged area causes temperatures to rise. For example, if you consider a circle of forest that’s 4km wide, and there’s a completely deforested, 2km-wide ring around it, the inner circle would warm on average by 1.2℃. The closer the forest loss, the higher the warming. If the ring was 1-2km away, the circle would warm by 3.1℃, while at 4-6km away, it’s 0.75℃. These might not sound like big increases in temperature, but global studies show <a href="https://www.pnas.org/content/114/35/9326.short">for each 1℃ increase in temperature</a>, yields of major crops would decline by around 3-7%. Retaining forest within 1km of agricultural land in Southeast Asia could therefore avoid crop losses of 10-20%. These estimates are conservative, because we only measured the effect of forest loss on average yearly temperatures. But another important factor is that higher average temperatures <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2011JD016382">usually create</a> higher temperature extremes, like those during heatwaves. And those really high temperatures in heatwaves are what put people and crops at most risk. Of course, forests aren’t normally cut down in rings. This analysis was designed to exclude other causes of temperature change, putting the effect of non-local forest loss in focus. <h2>Why is this happening?</h2> Forests cool the land because trees draw water from the soil to their leaves, where it then evaporates. The energy needed to evaporate the water comes from sunshine and heat in the air, the same reason you feel colder when you get out of a pool with water on your skin. A single tree in a tropical forest can cause <a href="https://www.sciencedirect.com/science/article/pii/S0959378017300134">local surface cooling equivalent</a> to 70 kilowatt hours for every 100 litres of water used from the soil — as much cooling as two household air conditioners. Forests are particularly good at cooling the land because their canopies have large surface area, which can evaporate a lot of water. When forests in tropical regions are cut down, this evaporative cooling stops, and the land surface warms up. This is not news to the people of Borneo. In 2018, researchers surveyed <a href="https://www.sciencedirect.com/science/article/pii/S0959378017314188">people in 477 villages</a>, and found they’re well aware nearby forest loss has caused them to live with hotter temperatures. When asked why forests were important to their health and the health of their families, the ability for trees to regulate temperature was the most frequent response. <a href="https://images.theconversation.com/files/431029/original/file-20211109-13-18wfaj.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/431029/original/file-20211109-13-18wfaj.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Logging road" /></a> A logging road in East Kalimantan, Bornea: logged forest on the left, virgin/primary forest on the right. <a href="https://upload.wikimedia.org/wikipedia/commons/a/ab/Logging_road_East_Kalimantan_2005.jpg" class="source">Aidenvironment, 2005/Wikimedia Commons</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" class="license">CC BY-SA</a> <h2>A climate change double whammy</h2> In many parts of the world, including the tropics and Australia, expanding farmland is a major reason for cutting down forest. But given hotter temperatures also reduce the productivity of farms, conserving forests might prove a better strategy for food security and for the livelihoods of farmers. If forests must be removed, there may be ways to avoid the worst possible temperature increases. For example, we found that keeping at least 10% of forest cover helped reduce the associated warming by an average of 0.2℃. Similarly, temperatures did not increase as much when the area of forest loss was smaller. This means if deforestation occurs in smaller, discontinuous blocks rather than uniformly, then the temperature impacts will be less severe. To help share these findings, <a href="https://treeheat.azurewebsites.net">we’ve built a web mapping tool</a> that lets users explore the effects of different patterns and areas of forest loss on local temperatures in maritime South East Asia. It helps show why protecting forests in the tropics offers a climate change double whammy – lowering carbon dioxide emissions and local temperatures together.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;" src="https://counter.theconversation.com/content/163584/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sally-thompson-1223399">Sally Thompson</a>, Associate professor, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a>; <a href="https://theconversation.com/profiles/debora-correa-1288935">Débora Corrêa</a>, Research fellow, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a>; <a href="https://theconversation.com/profiles/john-duncan-1288934">John Duncan</a>, Research fellow, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a>, and <a href="https://theconversation.com/profiles/octavia-crompton-1246306">Octavia Crompton</a>, Postdoctoral researcher, Pratt School of Engineering, <a href="https://theconversation.com/institutions/duke-university-1286">Duke University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Drying land and heating seas: why nature in Australia’s southwest is on the climate frontline

In a few days world leaders will descend on Glasgow for the United Nations climate change talks. Much depends on it. We know climate change is already happening, and nowhere is the damage more stark than in Australia’s southwest. The southwest of Western Australia has been <a href="https://www.ipcc.ch/report/ar6/wg1/downloads/factsheets/IPCC_AR6_WGI_Regional_Fact_Sheet_Australasia.pdf">identified</a> as a global drying hotspot. Since 1970, winter rainfall has declined up to 20%, river flows have plummeted and heatwaves spanning water and land have intensified. The Intergovernmental Panel on Climate Change <a href="https://theconversation.com/climate-change-has-already-hit-australia-unless-we-act-now-a-hotter-drier-and-more-dangerous-future-awaits-ipcc-warns-165396">warns</a> this will continue as emissions rise and the climate warms. Discussion of Australian ecosystems vulnerable to climate change often focuses on the Great Barrier Reef, as well as our rainforests and alpine regions. But for southwest Western Australia, climate change is also an existential threat. The region’s wildlife and plants are so distinctive and important, it was listed as Australia’s first <a href="https://www.cepf.net/our-work/biodiversity-hotspots">global biodiversity hotspot</a>. Species include thousands of endemic plant species and animals such as the quokka, numbat and honey possum. Most freshwater species and around 80% of marine species, including 24 shark species, live nowhere else on Earth. They <a href="https://theconversation.com/australias-south-west-a-hotspot-for-wildlife-and-plants-that-deserves-world-heritage-status-54885">evolved in isolation</a> over millions of years, walled off from the rest of Australia by desert. But climate heating means this remarkable biological richness is now imperilled – a threat that will only increase unless the world takes action. <img src="https://images.theconversation.com/files/428719/original/file-20211027-17-1xrecip.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Banksia in flower" /> Hooker’s Banksia is an iconic West Australian species. Dr Joe Fontaine, Author provided <h2>Hotter and drier</h2> Southwest WA runs roughly from Kalbarri to Esperance, and is known for its Mediterranean climate with very hot and dry summers and most rainfall in winter. But every decade since the 1970s, the region’s summertime maximum temperatures have risen 0.1-0.3℃, and winter rainfall has fallen 10-20 millimetres. <img src="https://images.theconversation.com/files/428742/original/file-20211027-25-1jl7l8r.gif?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="" /> Decadal trends in winter precipitation. Australian Bureau of Meteorology. And remarkably, a 1℃ increase in the average global temperature over the last century has already <a href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.17348">more than doubled</a> the days over 40℃ in Perth. <a href="https://images.theconversation.com/files/428994/original/file-20211028-21-ibw728.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/428994/original/file-20211028-21-ibw728.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="Graph showing temperatures over 40 degrees at Perth Airport" /></a> Cumulative number of days over 40° at Perth Airport over 30-year periods between 1910-1939 (historic) and 1989-2018 (current). Author provided This trend is set to continue. Almost all climate models <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019EF001469">project a further</a> drop in winter rainfall of up to 30% across most of the southwest by 2100, under a high emissions scenario. The southwest already has very hot days in summer, thanks to heat brought from the desert’s easterly winds. As climate change worsens, these winds are <a href="https://link.springer.com/article/10.1007/s00382-016-3169-5">projected to get more intense</a>, bringing still more heat. <h2>Drying threatens wildlife, wine and wheat</h2> Annual rainfall in the southwest has fallen by a fifth since 1970. That might not sound dangerous, but the drop means river flows have already fallen by an alarming 70%. It means many rivers and lakes now dry out through summer and autumn, causing major problems for freshwater biodiversity. For example, the number of invertebrate species in 17 lakes in WA’s wheatbelt fell from over 300 to <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.15890">just over 100</a> between 1998 and 2011. The loss of water has even killed off common river invertebrates, such as the endemic Western Darner dragonfly, with most now <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.15673">found only</a> in the last few streams that flow year round. The drying also makes it very hard for animals and birds to find water. Most native freshwater fish in the southwest are <a href="https://www.dpaw.wa.gov.au/plants-and-animals/threatened-species-and-communities/threatened-animals">now officially considered</a> “threatened”. As river flow falls to a trickle, fish can no longer <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.12444">migrate to spawn</a>, and it’s only a short march from there to extinction. To protect remaining freshwater species we must <a href="https://doi.org/10.1016/j.biocon.2017.02.007">develop perennial water refuges</a> in places such as farm dams. <a href="https://images.theconversation.com/files/428721/original/file-20211027-27-1mvytaa.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/428721/original/file-20211027-27-1mvytaa.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="Freshwater crayfish - marron - moving through fresh water" /></a> Smooth Marron moving as a group in a reservoir. Dr Stephen Beatty, Author provided The story on land is also alarming, with intensifying heatwaves and chronic drought. This was particularly dire in 2010/2011, when <a href="https://www.nature.com/articles/s41598-018-31236-5">all ecosystems in the southwest</a> suffered from a deadly drought and heatwave combination. What does that look like on the ground? Think beetle swarms taking advantage of forest dieback, a sudden die off of endangered Carnaby’s Black Cockatoos, and the deaths of one in five shrubs and trees. Long term, the flowering rates of banksias have declined <a href="https://esajournals.onlinelibrary.wiley.com/doi/abs/10.1890/140231">by 50%</a>, which threatens their survival as well as the honey industry. For agriculture, the picture is mixed. Aided by innovation and better varieties, wheat yields in the southwest have actually increased since the 1970s, despite the drop in rainfall. But how long can farmers stay ahead of the drying? If global emissions aren’t drastically reduced, droughts in the region <a href="https://agupubs.onlinelibrary.wiley.com/doi/pdfdirect/10.1029/2020GL087820">will keep getting worse</a>. Increased heating and drying will also likely threaten Margaret River’s famed wine region, although the state’s northern wine regions will be <a href="https://journals.ametsoc.org/view/journals/apme/56/7/jamc-d-16-0333.1.xml">the first at risk</a>. <h2>Hotter seas, destructive marine heatwaves</h2> The seas around the southwest are another climate change hotspot, <a href="https://link.springer.com/article/10.1007%2Fs11160-013-9326-6">warming faster than 90%</a> of the global ocean since the middle of last century. Ocean temperatures off Perth <a href="https://www.publish.csiro.au/mf/MF07082">have risen by an average</a> of 0.1-0.3℃ per decade, and are now almost 1℃ warmer than 40 years ago. The waters off the southwest are part of the <a href="https://theconversation.com/australias-other-reef-is-worth-more-than-10-billion-a-year-but-have-you-heard-of-it-45600">Great Southern Reef</a>, a temperate marine biodiversity hotspot. Many species of seaweeds, seagrasses, invertebrates, reef fish, seabirds and mammals live nowhere else on the planet. As the waters warm, species move south. Warm-water species move in and cool-water species flee to escape the heat. Once cool-water species reach the southern coast, there’s nowhere colder to go. They can’t survive in the deep sea, and are at risk of going extinct. <img src="https://images.theconversation.com/files/428961/original/file-20211028-27-1yipdxz.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" alt="Marine heatwave map" /> Temperature anomalies over land and ocean in March 2011. Scientific Reports, Author provided Marine heatwaves are now striking alongside this long-term warming trend. In 2011, a combination of weak winds, water absorbing the local heat from the air, and an unusually strong flow of the warm Leeuwin Current led to the infamous marine heatwave known as <a href="https://www.nature.com/articles/srep01277">Ningaloo Nino</a>. Over eight weeks, ocean temperatures soared by more than 5℃ above the long-term maximum. Coral bleached in the state’s north, fish died en masse, <a href="https://theconversation.com/how-much-do-marine-heatwaves-cost-the-economic-losses-amount-to-billions-and-billions-of-dollars-170008">34% of seagrass died</a> in Shark Bay, and kelp forests along 100km of WA’s coast were wiped out. Following the heatwave came sudden distribution changes for species like sharks, turtles and many reef fish. Little penguins starved to death because their usual food sources were no longer there. Recreational and commercial fisheries were forced to close to protect ailing stocks. Some of these fisheries have not recovered 10 years later, while others are only now reopening. This is just the start. <a href="https://www.frontiersin.org/articles/10.3389/fmars.2019.00734/full">Projections suggest</a> the southwest could be in a permanent state of marine heatwave within 20-40 years, compared to the second half of the 20th century. <a href="https://images.theconversation.com/files/428980/original/file-20211028-17-1o7ypsp.PNG?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/428980/original/file-20211028-17-1o7ypsp.PNG?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Comparative pictures of a kelp forest before and after a heatwave" /></a> Reef in Kalbarri before (left) and after (right) the 2011 Ningaloo Nino.

Barty's brilliantly blunt take on Tokyo heat

As the weather in Tokyo reached the mid-30s, many players have been complaining about being forced to play at the peak of the heat. But, Aussie tennis star Ash Barty had no qualms about the inclement weather and gave a blunt response when asked for her opinion on the conditions. “We’re Aussies, mate. We’re alright,” she told News Corp after her and Storm Sanders’ loss in the women’s doubles against Czech pair Barbora Krejcikova and Katerina Siniakova. Meanwhile, Spain’s Paula Badosa was taken off the court in a wheelchair after collapsing from heat exhaustion during her quarter-final match against Marketa Vondrousova. <blockquote class="twitter-tweet"> Suspect scenes like these may have played a part in the decision of Olympic organisers to take tennis out of the worst of the heat.

We tried to adapt as best as possible but today the body has not responded as needed. “I have suffered a heat stroke as you all have seen and I did not feel ready to continue.” Russian Daniil Medvedev also struggled with the soaring temperatures during his third round win over Fabio Fognini. Medvedev took two medical timeouts and asked who would be responsible for his death. “I can finish the match but I can die,” he told chair umpire Carlos Ramos when asked if he could continue. “If I die, are you going to be responsible?” <blockquote class="twitter-tweet"> Still alive🥵　<a href="https://twitter.com/Tokyo2020?ref_src=twsrc%5Etfw">@Tokyo2020</a> <a href="https://twitter.com/Olympics?ref_src=twsrc%5Etfw">@Olympics</a> <a href="https://t.co/xEJqMGUNsq">pic.twitter.com/xEJqMGUNsq</a> — Daniil Medvedev (@DaniilMedwed) <a href="https://twitter.com/DaniilMedwed/status/1420306048758554629?ref_src=twsrc%5Etfw">July 28, 2021</a></blockquote> “I just had darkness in my eyes, like between every point I didn’t know what to do to feel better. “I was bending over and I couldn’t get my breathing together.

Naomi Osaka's feud with Piers Morgan heats up

A Twitter feud has started between Naomi Osaka, conservative commentator Megan Kelly, and Piers Morgan, after Kelly and Morgan hit out at the tennis star over her recent magazine feature. Osaka recently appeared on the front cover of Sports Illustrated in a swimsuit photoshoot, making history as the first Japanese and Haitian woman to do so. After sharing the cover on her social media pages, Osaka attracted criticism for appearing in the media after her recent break from the spotlight. Since taking time away from the tennis court on mental health grounds, Osaka has announced a collaboration with Barbie for her ‘Role Model’ doll, a Netflix mini-series about her, and made appearances in Vogue, Time Magazine, and Sports Illustrated. All of these media engagements would have been in the works for months, but sports pundit Clay Travis called Osaka out for her latest media appearances during her break. Kelly and Morgan echoed their support for his criticisms. “Since saying she’s too introverted to talk to the media after tennis matches, Naomi Osaka has launched a reality show, a Barbie, and now is on the cover of the SI swimsuit issue,” Travis said on Twitter. <blockquote class="twitter-tweet"> Let’s not forget the cover of (& interview in) Vogue Japan and Time Mag! <a href="https://t.co/PAAUEwAVi0">https://t.co/PAAUEwAVi0</a> — Megyn Kelly (@megynkelly) <a href="https://twitter.com/megynkelly/status/1417154841898622977?ref_src=twsrc%5Etfw">July 19, 2021</a></blockquote> <blockquote class="twitter-tweet"> ANOTHER magazine cover for brave inspiring Naomi!

But, after appearing to block Kelly, the commentator continued the attack on the tennis star. <blockquote class="twitter-tweet"> Poor <a href="https://twitter.com/naomiosaka?ref_src=twsrc%5Etfw">@naomiosaka</a> blocked me while taking a shot at me (guess she’s only tough on the courts). She is apparently arguing that she shot her many covers b/4 publicly claiming she was too socially anxious to deal w/press. Truth is she just doesn’t like Qs she can’t control. Admit it. <a href="https://t.co/izyRzOrUVm">pic.twitter.com/izyRzOrUVm</a> — Megyn Kelly (@megynkelly) <a href="https://twitter.com/megynkelly/status/1417193630671032320?ref_src=twsrc%5Etfw">July 19, 2021</a></blockquote> Morgan also weighed-in, saying he has been blocked by Osaka as well. <blockquote class="twitter-tweet"> Yep, and she just blocked me too. The only media Ms Osaka wants to tolerate are sycophantic magazine editors telling her how perfect she is. <a href="https://t.co/oLcyJviR4v">https://t.co/oLcyJviR4v</a> — Piers Morgan (@piersmorgan) <a href="https://twitter.com/piersmorgan/status/1417194272886038534?ref_src=twsrc%5Etfw">July 19, 2021</a></blockquote> However, others were quick to jump to Osaka’s defence, including tennis great Martina Navratilova. “A**hole much, Megyn?!? You have no idea what you are talking about. But go ahead and take your shot. It missed badly!!!” Navratilova tweeted.

Dispute heats up over Prince Charles and Prince Harry's finances

A new argument has broken out between Prince Charles and Prince Harry over money. Newly-released information about accounts has shown that Prince Charles continued to support his son and Meghan Markle as they stepped down as senior members of the royal family. He continued to provide funds to the Duke and Duchess of Sussex from his Duchy of Cornwall fund until the last quarter of 2020. In a statement, a spokesman for Charles said that “the Prince of Wales allocated a substantial sum” to Harry and Meghan last year “to support them” with their transition in stepping down and relocating to California. “That funding ceased in the summer of last year.” “The couple are now financially independent,” they added. This contradicts the claims Prince Harry made during that Oprah interview where he said that his father had cut him off financially. A representative for the Sussex family has insisted there is no difference in the timeline. “You are conflating two different timelines and it’s inaccurate to suggest that there’s a contradiction,” the spokesperson said, according to <a rel="noopener" href="https://www.independent.co.uk/news/uk/home-news/prince-harry-meghan-markle-charles-finances-b1871723.html" target="_blank">The Independent.</a> “The Duke’s comments during the Oprah interview were in reference to the first quarter of the fiscal reporting period in the UK, which starts annually in April. “This is the same date that the ‘transitional year’ of the Sandringham agreement began and is aligned with the timeline that Clarence House referenced.”
