Summer’s over, so how much sun can (and should) I get?

<p><em><a href="https://theconversation.com/profiles/katie-lee-228942">Katie Lee</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/rachel-neale-891731">Rachel Neale</a>, <a href="https://theconversation.com/institutions/qimr-berghofer-medical-research-institute-1811">QIMR Berghofer Medical Research Institute</a></em></p> <p>As we slide of out summer, you might be wondering how careful you need to be about sun exposure. Excessive exposure causes <a href="https://www.cancer.org.au/about-us/policy-and-advocacy/prevention-policy/national-cancer-prevention-policy/skin-cancer-statistics-and-issues/uv-radiation">skin cancer</a>, but sun exposure also has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">benefits</a>. How do you balance the two?</p> <p>A new <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">position statement</a> from cancer, bone health and other experts <a href="https://www.assc.org.au/wp-content/uploads/2023/01/Sun-Exposure-Summit-PositionStatement_V1.9.pdf">aims to help</a> Australians balance the good and bad effects of sun exposure by taking into account their skin colour, risk of skin cancer, and where they live.</p> <h2>What are the benefits of sunlight?</h2> <p>Ultraviolet (UV) radiation (the wavelengths in sunlight that cause skin cancer) also leads to vitamin D production. <a href="https://dermnetnz.org/topics/vitamin-d">Vitamin D</a> is very important for maintaining strong bones, and is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">multiple other health benefits</a>.</p> <p>But vitamin D probably isn’t the whole story. Sunshine, including UV radiation, is thought to affect health in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">other ways</a> such as improving our mood and reducing the risk of autoimmune diseases and infections. So for many people, avoiding the sun and taking a vitamin D supplement may not be the best approach.</p> <h2>How much time does it take to make vitamin D?</h2> <p>It’s complicated, but for most people and most of the year across most of Australia, it’s a lot less than you think.</p> <p>The <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">amount of time needed</a> depends on the amount of skin covered by clothing and the intensity of UV radiation (indicated by the UV index). More skin exposed and higher UV index equate to less time needed.</p> <p>Both the UV index and the amount of the year that UV radiation is high increase as you get closer to the equator. In summer, all of Australia is bathed in sunshine. But in winter, opposite ends of the country have <a href="https://onlinelibrary.wiley.com/doi/10.1111/php.13854">very different exposures</a>.</p> <p>In summer, everybody except those with deeply pigmented skin can make enough vitamin D in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">just five minutes</a> between 9am and 3pm, anywhere in Australia, provided they are wearing shorts and a T-shirt.</p> <p>In winter it’s a different story. In <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Darwin and Brisbane</a>, 5–10 minutes between 10am and 3pm will do the trick, but in <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">Hobart</a>, factoring in winter clothing, it will take nearly an hour in the middle of the day.</p> <p>Hover your mouse over the lines below to see the length of exposure needed at specific times of day.</p> <p><iframe id="X5szQ" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/X5szQ/" width="100%" height="400px" frameborder="0"></iframe></p> <p>Staying out for longer than needed doesn’t necessarily make more vitamin D, but it <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib25">does cause skin damage</a>.</p> <h2>Hang on, what about those with darker skin?</h2> <p>People with deeply pigmented, brown to black skin accumulate both vitamin D and DNA damage at a much slower rate than people with lighter skin tones.</p> <p>When UV radiation hits a DNA strand, it causes the DNA to become distorted. If the distortion isn’t fixed, it will cause a mistake when the DNA is copied for a new cell, causing a permanent mutation that sometimes leads to cancer.</p> <p>Melanin, the brown pigment in the skin, absorbs UV photons before that can happen, and the high melanin content in the darkest skin tones provides <a href="https://faseb.onlinelibrary.wiley.com/doi/full/10.1096/fj.201701472R">60 times</a> as much UV protection as the small amount in very fair skin.</p> <p>The flip side is the risk of vitamin D deficiency is much higher than the risk of skin cancer.</p> <p>The new statement accounts for this by putting people into <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">three groups</a> based on their risk of skin cancer, with specialised advice for each group.</p> <h2>Highest skin cancer risk</h2> <p>This includes people with very pale skin that burns easily and tans minimally, but also people with darker white or olive skin who can tan easily but have extra skin cancer risk factors because they:</p> <ul> <li>have had <strong>skin cancer</strong> before</li> <li>have a <strong>family history</strong> of melanomas</li> <li>have many <strong>moles</strong></li> <li>are taking <strong>immunosuppressant</strong> medications.</li> </ul> <p>For these people, the harms of sun exposure almost certainly <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub">outweigh the benefits</a>.</p> <p>These people should wear sunscreen every day the <a href="https://www.arpansa.gov.au/our-services/monitoring/ultraviolet-radiation-monitoring/ultraviolet-radiation-index">UV index</a> is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, and use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">five sunsmart steps</a> whenever the UV index is above three:</p> <ul> <li><strong>slip</strong> on clothing covering as much of the body as possible</li> <li><strong>slop</strong> on SPF30+ sunscreen on areas that can’t be covered up</li> <li><strong>slap</strong> on a hat</li> <li><strong>seek</strong> shade</li> <li><strong>slide</strong> on sunglasses.</li> </ul> <p>They shouldn’t spend time outdoors deliberately to make vitamin D, but should discuss vitamin D supplements with their doctor.</p> <h2>Intermediate skin cancer risk</h2> <p>This means people with dark white/olive skin that sometimes burns but tans easily, and who don’t have other skin cancer risk factors.</p> <p>These people should still apply sunscreen as part of their usual routine on all days when the UV index is forecast to get to <a href="https://www.assc.org.au/peak-health-bodies-recommend-new-approach-to-sunscreen-use/">three or more</a>, but they can spend enough time outdoors to get a “dose” of vitamin D on most days of the week.</p> <p>Once the time needed for their vitamin D dose is up, they should also use the <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">slip-slop-slap-seek-slide</a> steps to avoid accumulating DNA damage.</p> <p>If they’re unable to do this because of health or lifestyle factors, like being housebound, working night shifts, or always covering up with clothing, they should see their doctor about whether they need vitamin D supplements.</p> <h2>Lowest skin cancer risk</h2> <p>This covers people with deeply pigmented brown to black skin that rarely or never burns.</p> <p>These people can <a href="https://www.sciencedirect.com/science/article/pii/S1326020023052949?via%3Dihub#bib14">safely spend enough time outdoors</a> to make vitamin D and get the other benefits of sunshine. But because more time is needed, it can be difficult, particularly when the weather is cold. Vitamin D supplements might be needed.</p> <p>They don’t need to routinely protect their skin, but might need to <a href="https://www.cancer.org.au/cancer-information/causes-and-prevention/sun-safety/be-sunsmart">slip-slop-slap-seek-slide</a> if they are outdoors for more than two hours.</p> <h2>How do I get the feel-good effects of sunshine?</h2> <p>Spending time outdoors in the early morning is the best way to get the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9976694/">feel-good effects</a> of sunshine. An early morning walk is a great idea for all of us, but it won’t make vitamin D.<!-- Below is The Conversation's page counter tag.

Why you should travel solo this summer

<p><em><a href="https://theconversation.com/profiles/claire-mccamley-446927">Claire McCamley</a>, <a href="https://theconversation.com/institutions/university-of-huddersfield-1226">University of Huddersfield</a></em></p> <p>When you think about booking a summer holiday, you might think of trips with partners, friends or family. The idea of going on holiday alone can be daunting, or even unappealing. It raises all kinds of questions – who will you talk to? Who will you eat with? Will you be safe?</p> <p>There has long been a <a href="https://www.tandfonline.com/doi/abs/10.1080/0267257X.2015.1073170?journalCode=rjmm20">stigma against solo consumption</a>. Societal norms encourage us to be with someone – leisure experiences are billed as something to <a href="https://www.emerald.com/insight/content/doi/10.1108/IJCHM-06-2019-0584/full/pdf?title=dining-alone-improving-the-experience-of-solo-restaurant-goers">share with others</a>. There may also be a level of guilt or self-indulgence associated with solo travel, feeling as if you are shirking responsibility or abandoning time with family.</p> <p>An increase in <a href="https://www.euromonitor.com/article/single-person-households-to-record-128-percent-growth-by-2030">single-person households</a>, however, means the hospitality industry is now serving solo consumers in addition to families and couples. The continuously <a href="https://www.forbes.com/sites/adigaskell/2020/05/11/is-a-blurred-work-life-balance-the-new-normal/?sh=5c9db6341813">blurred line</a> between work and play, particularly for Millennials and younger generations, makes it easier to work remotely or travel as part of our jobs. We are more transient than ever, and have more opportunities to work and travel alone without feeling completely disconnected from the rest of our lives.</p> <p>In recent years, people have been <a href="https://www.telegraph.co.uk/travel/comment/whats-behind-the-rise-in-solo-travel/">increasingly</a> travelling alone – including younger vacationers. They also share their experiences to a large audience on social media – the hashtag #SoloTravel has over 7 million posts associated with it on Instagram. Solo travellers are taking part in the growing <a href="https://www.futuresplatform.com/blog/solo-economy-new-consumption-patterns">solo economy</a> – new products and services targeting the lone consumer.</p> <p>Hotels, <a href="https://www.ncl.com/uk/en/freestyle-cruise/solo-cruising">cruises</a>, restaurants, tourism <a href="https://www.flashpack.com/">companies</a> and festivals are showing how design, staff and technology can be tailored to accommodate – and even encourage – solo consumption in travel. <a href="https://journals.sagepub.com/doi/10.1177/14705931211017184">Our research</a> into the experience of solo consumers in coffee shops offers insight into how solo consumption can be as pleasurable and fulfilling as going with a partner or friend. Through <a href="https://www.research.ucsb.edu/sites/default/files/RD/docs/FREEWRITING-by-Peter-Elbow.pdf">freewriting</a> exercises, these consumers shared their own experiences. Their words offer some reasons you should try it too.</p> <h2>Be together, alone</h2> <p>Our research participants highlighted key factors that help them enjoy their solo experience – high seats and window views allowing them to sit back and observe others’ lives without any direct interaction or connection. You don’t need to arrive with others to feel part of a social environment. Alone in a crowded square or on a busy beach, the proximity of other people and their conversations can be a source of comfort, distraction or even entertainment.</p> <blockquote> <p>The seat is important -– I like the window especially a stool and “shelf” table facing out … I see people, imagine their lives, see cars and life pass by. I watch other customers, I watch the street out the window, the cliché of “watching the world pass by”. The setting, context and environment of the café are important to that moment of pause.</p> </blockquote> <h2>Take time for yourself</h2> <p>Being alone can be a <a href="https://journals.sagepub.com/doi/pdf/10.1177/14705931211017184">therapeutic experience</a>, a time to process thoughts, feelings and emotions and leave you ready to tackle the world again. Perhaps take time to write, draw or practice another creative activity in your own time. Bask in your own thoughts without feeling pressure to please anyone else or force a conversation.</p> <blockquote> <p>Sitting alone with my thoughts can be a comforting experience; picking a seat, getting comfy…I can find silence with my thoughts and don’t feel any pressure to act for anybody or involve myself in a conversation that doesn’t interest me.</p> </blockquote> <h2>Get out of your comfort zone</h2> <p>Being able to do your own thing, without needing to consider others can be relaxing and can also give you the opportunity to do something you’ve never done before, free of judgement. You might want to go to some sort of class, shop or have a complete chill-out day.</p> <p>Findings from our research indicate that time spent doing things alone can relieve some of the pressures that companions can bring. Alone time gives you the space to experience things in your own time and take in your surroundings without distraction. In doing this, you may find yourself in new situations, away from your comfort zone – an energising and enthralling experience.</p> <h2>Embrace solo traveller culture</h2> <p>Solo travellers have their <a href="https://www.sciencedirect.com/science/article/pii/S0278431921002516">own way of doing things</a>, they have a shared behaviour and process and often become a collective in themselves. They acknowledge the process of travelling alone and respect others doing the same, and may even seek out spaces to be alone, together. Solo travellers can engage in a shared experience and dialogue while maintaining their own individualism – helping each other when needed, but also leave one another alone.</p> <blockquote> <p>We search for places where we feel we fit … We are happy to smile at one another. We don’t need to chat to engage. We are happy on our own with a coffee. I am amongst my tribe.<!-- Below is The Conversation's page counter tag.

Our dogs can terrify (and even kill) wildlife. Here’s how to be a responsible owner this summer

<p><em><a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>In Australia, dog ownership often goes hand-in-hand with a love for the great outdoors. Whether it’s walking on the beach, going camping, or having a barbecue in the park, we tend to keep our canine companions close as we soak up the sun.</p> <p>But many of us forget a key fact about our dogs: they are predators. Even the fluffy little 5kg ball that spends most of its time in your lap derives from an apex predator – and its predatory instincts can kick in at any time.</p> <p>And while many of our dogs don’t have the same hunting skills as their distant ancestors (who had to hunt for a living), wildlife doesn’t know that.</p> <p>The impacts of domestic dogs on wildlife aren’t well studied, and likely vary depending on the environment. Nonetheless, there’s good evidence domestic dogs, when left unobserved, can have detrimental effects in the places they visit.</p> <p>With that in mind, here are some things to consider next time you take your pup out for a bushwalk.</p> <h2>How dogs impact ecosystems</h2> <p>There are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717305967">five main ways</a> domestic dogs can negatively impact the natural environments they visit. These are:</p> <ol> <li>direct physical harm through predatory behaviour</li> <li>disturbance through chasing and harassment</li> <li>increased exposure to diseases</li> <li>interbreeding, which can alter the gene pool of wild canid populations</li> <li>increased competition for resources.</li> </ol> <p>The good news is the last three points aren’t particularly relevant in Australia. For one thing, there’s little overlap between diseases common in domestic dogs and Australian wildlife. There’s also little resource overlap, except perhaps in some areas where feral or semi-feral dogs live alongside dingoes.</p> <p>And regarding potential interbreeding, while it was once thought this could threaten the dingo gene pool, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/mec.16998">recent research</a> suggests it’s not nearly as common as we thought.</p> <p>As such, the main harms Aussie dog owners should focus on are physical harms through predatory behaviour and disturbance to ecosystems.</p> <h2>Dogs can kill</h2> <p>We know dogs are capable of injuring and killing wildlife, but it’s difficult to determine how common this is, because many events go unreported. While smaller animals such as lizards, gliders and possums are at higher risk, larger species such as koalas can also fall prey to dogs.</p> <p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0206958">One study</a> that looked at wildlife coming into care at Queensland rehabilitation centres reported dog attacks as the cause in about 9% of cases. These cases often resulted in severe injury or death.</p> <p>Dog owners should be especially wary of small, localised populations of vulnerable species. A <a href="https://ri.conicet.gov.ar/bitstream/handle/11336/202640/CONICET_Digital_Nro.29048152-7a5c-4ea2-8068-e73d42cba01d_B.pdf?sequence=2&amp;isAllowed=y">study</a> in Argentina’s Patagonia region details several cases of dogs decimating local penguin populations after gaining access to protected island areas during low tide.</p> <p>Not to mention, dog attacks on wildlife can bring risk to dogs as well. Kangaroos can defend themselves with <a href="https://www.abc.net.au/news/2023-10-16/mildura-man-fights-kangaroo-to-protect-dog/102983926">their powerful limbs</a>, monitor lizards are equipped with sharp claws and teeth, and many snake species <a href="https://www.brisbanetimes.com.au/national/queensland/dogs-twice-as-likely-to-die-from-snake-bite-as-cats-research-finds-20200519-p54ufd.html">are highly venomous</a>.</p> <h2>The impact of harassment</h2> <p>You might think it’s harmless for your dog to chase wildlife if it never manages to catch the animals it chases, but that isn’t true. Wild animals optimise their behaviours to meet their needs for foraging, breeding and resting, and being chased by a dog can disrupt this.</p> <p>For example, certain threatened bird species will nest on the beach and find foraging opportunities based on the tides. One dog forcing one bird to abandon this important activity may have a small impact. But if it happens repeatedly throughout the day, it can become a <a href="https://wilderness-society.org/wp-content/uploads/2019/04/Dogs-as-agents-of-disturbance-Michael-A.-Weston-and-Theodore-Stankowich.pdf">much bigger problem</a>. It may even drive animals out of the area.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2391219/">Research</a> conducted in Sydney has shown the mere presence of a leashed dog is enough to temporarily, yet dramatically, reduce the number of bird species detected.</p> <h2>Keep an eye on your furry pal</h2> <p>Responsible dog ownership involves making sure our dogs have a minimal impact on others, including wildlife. How can we achieve this when our dogs are simply engaging in behaviours that come naturally to them, and may even be rewarding for them?</p> <p>Training your dog to have general obedience – especially to come when called – is worth sinking considerable time and effort into. This can save both your dog and any wildlife they may be after. For instance, calling a dog away from a snake is one of the most effective ways of managing snake bite risk.</p> <p>One <a href="https://www.researchgate.net/publication/333344634_Applying_Social_Marketing_to_Koala_Conservation_The_Leave_It_Pilot_Program">pilot study</a> in Victoria found positive outcomes from a program that helped owners train their dogs to be more obedient around wildlife.</p> <p>That said, recall training is an art form, and recalling a dog that likes to run off and chase animals can be a huge challenge.</p> <p>Another solution is to rely on leashes when passing sensitive areas, or where there’s a risk of wildlife harassment. In Australia, many beaches that allow dogs have signs with information about vulnerable birds in the area and how to protect them from your dog.</p> <p>This could mean keeping your dog off rock platforms, leashing them when you see birds foraging on the beach, or keeping them out of fenced areas. Some areas are simply too vulnerable for dogs to run amok, so always look for signs and read them carefully.</p> <p>If you’re hiking, use a long line (a leash that’s more than five metres long) and look for signs of your dog detecting something of interest. Often their ears will come up high and forward, and they will freeze and stare intently.</p> <p>At this point, it doesn’t matter what they’re excited about: take the opportunity to leash them or shorten their leash, and get their attention before they can take off. Investing in a long leash will allow your dog more freedom without putting wildlife at risk.</p> <p>If your dog does injure an animal, you should quickly contact a wildlife rescue organisation or take the animal to a veterinary practice or sanctuary. For small animals, even minor injuries from a dog will usually require veterinary attention.</p> <p>It’s our responsibility to be respectful visitors when we’re out in nature, and to make sure our dogs are too. <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/214722/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/melissa-starling-461103"><em>Melissa Starling</em></a><em>, Postdoctoral Researcher in Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

<p><em><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></em></p> <p>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.</p> <p>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.</p> <p>Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke.</p> <h2>What are the signs and symptoms?</h2> <p>If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second.</p> <h2>Why do we overheat?</h2> <p>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.</p> <p>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.</p> <p>Sweating is by far our most effective physiological means of keeping cool. However, it is the <em>evaporation</em> of sweat from our skin that provides cooling relief.</p> <p>When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates.</p> <p>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.</p> <p>Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool.</p> <h2>Who is most vulnerable in the heat?</h2> <p>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.</p> <p>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.</p> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>How to stay safe in the heat</h2> <p>Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat. These include: <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/215084/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <ul> <li>staying adequately hydrated</li> <li>getting out of the heat to a cooler area indoors or shaded area outdoors</li> <li>loosening or removing clothing</li> <li>cooling down any way you can: <ul> <li>using an electric fan (which can be used at 37°C and below, irrespective of age and humidity)</li> <li>using a cold-water spray</li> <li>applying a cool, damp sponge or cloth</li> <li>wetting clothes and skin</li> <li>having a cool shower or bath</li> <li>applying ice packs or crushed ice in a damp towel on the neck, groin and armpits.</li> </ul> </li> </ul> <p><a href="https://theconversation.com/profiles/lily-hospers-1060107"><em>Lily Hospers</em></a><em>, PhD Candidate, <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>, Post-doctoral Research Associate, <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>, Professor of Heat &amp; Health; Director of Heat &amp; Health Research Incubator; Director of Thermal Ergonomics Laboratory, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s warming up and mozzies are coming. Here’s how to mosquito-proof your backyard

<p><em><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>The weather is warming up and that means more time in the backyard. It also means more mosquitoes.</p> <p>Here are five ways you can mosquito-proof your backyard that <a href="https://theconversation.com/the-battle-against-bugs-its-time-to-end-chemical-warfare-111629">don’t rely on spraying insecticides</a>.</p> <h2>1. Get rid of water</h2> <p>Mosquitoes need water to complete their life cycles. They <a href="https://theconversation.com/feel-like-youre-a-mozzie-magnet-its-true-mosquitoes-prefer-to-bite-some-people-over-others-128788">need blood</a> – but water and warmth are just as important.</p> <p>Getting rid of water around your backyard will go a long way to keeping mosquitoes away. Water trapped in blocked roof gutters, drains and tarpaulin covering boats and trailers can be a great home for mosquitoes.</p> <p>Mosquitoes can exploit the tiniest of water sources too. It may just be the upturned lid of a discarded plastic drink bottle. If it traps water, mosquitoes will find it and lay eggs in it.</p> <p>Flush out your bird bath once a week to disrupt the mosquito’s life cycle.</p> <p>If you have a pond, installing a fountain will discourage mosquitoes. If you can’t keep water clean and circulating, consider filling it with sand and gravel to create an interesting garden bed for succulents or other plants.</p> <p>Mosquitoes will avoid clean and chlorinated swimming pools but will quickly move into “green pools”. If you’re not using your pool, consider <a href="https://www.krg.nsw.gov.au/Environment/Your-local-environment/Wildlife/Living-with-wildlife/Pool-to-pond/How-to-convert-your-pool">converting it to a “pond”</a> so that fish can help keep mosquito numbers down.</p> <h2>2. Screen up – windows, doors and rainwater tanks</h2> <p>If you can’t get rid of permanent water, at least stop mosquitoes getting to it (or you).</p> <p>Ensure <a href="https://www.brisbane.qld.gov.au/clean-and-green/natural-environment-and-water/water/water-smart-homes/rainwater-tanks/using-your-rainwater-tank">rainwater and septic tanks</a> have screens to stop mosquitoes entering.</p> <p>Screen windows and doors to stop mosquitoes entering the home. There are plenty of flexible screening options for windows, doors and balconies.</p> <p>If you live in a mosquito-prone area, creating a screened outdoor area (such as a pergola, courtyard, or balcony) will give you the opportunity to spend time outdoors without being hassled by mozzies.</p> <h2>3. Choose your garden plants carefully</h2> <p>Some plants <a href="https://bioone.org/journals/Journal-of-the-American-Mosquito-Control-Association/volume-25/issue-3/09-0016.1/Are-Commercially-Available-Essential-Oils-from-Australian-Native-Plants-Repellent/10.2987/09-0016.1.short">contain essential oils and other chemicals</a> that, when extracted and concentrated, provide protection against biting mosquitoes. But there isn’t a lot of evidence that the whole plant will keep mosquitoes away from your garden.</p> <p>Some types of plants are even marketed as “mozzie blockers” or “mosquito repelling”. But there isn’t <a href="https://www.veranda.com/outdoor-garden/a40592197/do-mosquito-repelling-plants-work/">any evidence of effectiveness</a>. In fact, some of these plants, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1440-6055.2009.00736.x">such as melaleucas</a>, also happen to be associated with <a href="https://academic.oup.com/jme/article/36/4/515/903838">hot spots of mosquito breeding</a> in coastal Australia.</p> <p>The plants to <em>avoid</em> around the home are those that help mosquitoes breed, such as <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1440-6055.2008.00641.x">bromeliads</a>, which trap water.</p> <h2>4. Encourage the animals that eat mosquitoes</h2> <p>Mosquitoes are food for a range of animals including birds, bats, fish, frogs, lizards, insects, spiders and <a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2656.13965">dragonflies</a>. But don’t expect them to eat enough to keep all mosquitoes away.</p> <p>Bats are often promoted as a good “biological control” options but studies have shown mosquitoes are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077183">more likely to be a snack food</a> for small bats, not an irresistible staple of their diet.</p> <p>For garden ponds, frogs will eat a few adult mosquitoes but tadpoles of Australian frogs generally <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-21/issue-4/8756-971X(2006)21%5b492%3aTOFCAF%5d2.0.CO%3b2/TADPOLES-OF-FOUR-COMMON-AUSTRALIAN-FROGS-ARE-NOT-EFFECTIVE-PREDATORS/10.2987/8756-971X(2006)21%5B492:TOFCAF%5D2.0.CO;2.short">don’t eat many mosquito “wrigglers”</a>.</p> <p>Australian native fish <a href="https://pubmed.ncbi.nlm.nih.gov/15532929/">will readily eat mosquitoes</a> and may be useful for backyard ponds.</p> <p>But not all fish are good. While “mosquitofish” (aka “plague minnow”) is distributed overseas to assist in mosquito control, <a href="https://meridian.allenpress.com/australian-zoologist/article/30/3/316/134508/Does-predation-by-the-fish-Gambusia-holbrooki">it’s a disaster for local wildlife</a> and, <a href="https://www.dpi.nsw.gov.au/fishing/aquatic-biosecurity/pests-diseases/freshwater-pests/finfish-species/gambusia">along with other exotic fish species</a>, should not be released into local waterways.</p> <p><a href="https://link.springer.com/article/10.1007/s13157-019-01133-2">Healthier habitats promote fewer mosquitoes</a> so the best thing you can do is create habitats for the animals that eat mosquitoes.</p> <h2>5. Avoid traps and other gadgets</h2> <p>There are lots of devices purported to catch, kill, or repel mosquitoes from your garden. Some may catch a mosquito or two but they’re not very effective in knocking out big numbers.</p> <p>“Bug zappers” with bright lights will collect lots of flying insects. It’s just that mosquitoes make up a very small proportion of collections.</p> <p>Electrocuting devices, again, don’t seem to attract a lot of mosquitoes.</p> <p>Devices that <a href="https://theconversation.com/the-buzz-from-your-smartphone-wont-stop-mosquito-bites-92611">emit high frequency sounds</a> won’t help either.</p> <p>The best devices are typically those that are baited with carbon dioxide. These are a mainstay of state and territory <a href="https://www.health.nsw.gov.au/Infectious/mosquito-borne/Pages/surveillance.aspx">mosquito and arbovirus surveillance programs</a>. For a mosquito, the C0₂ tricks them into thinking the trap is a warm-blooded animal. The only problem is these can be expensive to run and don’t seem quite as effective for mosquito control <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-22/issue-3/8756-971X(2006)22%5b490%3aTATTFA%5d2.0.CO%3b2/Traps-and-Trapping-Techniques-for-Adult-Mosquito-Control/10.2987/8756-971X(2006)22%5B490:TATTFA%5D2.0.CO;2.short">unless used in large numbers</a>.</p> <h2>Yes, you’ll still need repellent</h2> <p>Perhaps the best way to avoid mosquito bites is to pick an insect repellent <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">recommended by health authorities</a> and <a href="https://theconversation.com/mozzies-biting-heres-how-to-choose-a-repellent-and-how-to-use-it-for-the-best-protection-150183">apply it</a> to ensure all exposed areas of skin are covered.

Arctic Ocean could be ice-free in summer by 2030s, say scientists – this would have global, damaging and dangerous consequences

<p><a href="https://theconversation.com/profiles/jonathan-bamber-102567">Jonathan Bamber</a>, <em><a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>The Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. That’s the worrying conclusion of a new study in <a href="https://www.nature.com/articles/s41467-023-38511-8">Nature Communications</a>.</p> <p>Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown, but it would have global, damaging and dangerous consequences.</p> <p>The Arctic has been experiencing climate heating <a href="https://theconversation.com/arctic-is-warming-nearly-four-times-faster-than-the-rest-of-the-world-new-research-188474">faster than any other part of the planet</a>. As it is at the frontline of climate change, the eyes of many scientists and local indigenous people have been on the sea ice that covers much of the Arctic Ocean in winter. This thin film of frozen seawater expands and contracts with the seasons, reaching a minimum area in September each year.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=184&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=184&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=184&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=232&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=232&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=232&amp;fit=crop&amp;dpr=3 2262w" alt="Animation of Arctic sea ice from space" /></a><figcaption><span class="caption">Arctic sea ice grows until March and then shrinks until September.</span> <span class="attribution"><a class="source" href="https://www.nasa.gov/feature/esnt/2022/nasa-finds-2022-arctic-winter-sea-ice-10th-lowest-on-record">NASA</a></span></figcaption></figure> <p>The ice which remains at the end of summer is called multiyear sea ice and is considerably thicker than its seasonal counterpart. It acts as barrier to the transfer of both moisture and heat between the ocean and atmosphere. Over the past 40 years this multiyear sea ice has shrunk from around <a href="http://polarportal.dk/en/sea-ice-and-icebergs/sea-ice-extent0/">7 million sq km to 4 million</a>. That is a loss equivalent to roughly the size of India or 12 UKs. In other words, it’s a big signal, one of the most stark and dramatic signs of fundamental change to the climate system anywhere in the world.</p> <p>As a consequence, there has been considerable effort invested in determining when the Arctic Ocean might first become ice-free in summer, sometimes called a “blue ocean event” and defined as when the sea ice area drops below 1 million sq kms. This threshold is used mainly because older, thicker ice along parts of Canada and northern Greenland is expected to remain long after the rest of the Arctic Ocean is ice-free. We can’t put an exact date on the last blue ocean event, but one in the near future would likely mean open water at the North Pole for the first time in <a href="https://www.nature.com/articles/nature10581">thousands of years</a>.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=3 2262w" alt="Annotated map of Arctic" /></a><figcaption><span class="caption">The thickest ice (highlighted in pink) is likely to remain even if the North Pole is ice-free.</span> <span class="attribution"><a class="source" href="https://nsidc.org/arcticseaicenews/2015/05/new-tools-for-sea-ice-thickness/">NERC Center for Polar Observation and Modelling</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <p>One problem with predicting when this might occur is that sea ice is notoriously difficult to model because it is influenced by both atmospheric and oceanic circulation as well as the flow of heat between these two parts of the climate system. That means that the climate models – powerful computer programs used to simulate the environment – need to get all of these components right to be able to accurately predict changes in sea ice extent.</p> <h2>Melting faster than models predicted</h2> <p>Back in the 2000s, an assessment of early generations of climate models found they generally <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2007GL029703">underpredicted the loss of sea ice</a> when compared to satellite data showing what actually happened. The models predicted a loss of about 2.5% per decade, while the observations were closer to 8%.</p> <p>The next generation of models did better but were <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2012GL052676">still not matching observations</a> which, at that time were suggesting a blue ocean event would happen by mid-century. Indeed, the latest <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/">IPCC climate science report</a>, published in 2021, reaches a similar conclusion about the timing of an ice-free Arctic Ocean.</p> <p>As a consequence of the problems with the climate models, some scientists have attempted to extrapolate the observational record resulting in the controversial and, ultimately, incorrect assertion that this would happen <a href="https://www.theguardian.com/environment/2016/aug/21/arctic-will-be-ice-free-in-summer-next-year">during the mid 2010s</a>. This did not help the credibility of the scientific community and its ability to make reliable projections.</p> <h2>Ice-free by 2030?</h2> <p>The scientists behind the latest study have taken a different approach by, in effect, calibrating the models with the observations and then using this calibrated solution to project sea ice decline. This makes a lot of sense, because it reduces the effect of small biases in the climate models that can in turn bias the sea ice projections. They call these “observationally constrained” projections and find that the Arctic could become ice-free in summer as early as 2030, even if we do a good job of reducing emissions between now and then.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=3 2262w" alt="Walruses on ice floe" /></a><figcaption><span class="caption">Walruses depend on sea ice.

As it dramatically reduces the amount of sunlight absorbed by the ocean, removing this ice is predicted to further accelerate warming, through a process known as a positive feedback. This, in turn, will make the Greenland ice sheet <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2014GL059770">melt faster</a>, which is already a major contributor to <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021RG000757">sea level rise</a>.</p> <p>The loss of sea ice in summer would also mean changes in <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/ccp6/">atmospheric circulation and storm tracks</a>, and fundamental shifts in ocean biological activity. These are just some of the <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021RG000757">highly undesirable consequences</a> and it is fair to say that the disadvantages will far outweigh the slender benefits.</p> <p><a href="https://theconversation.com/profiles/jonathan-bamber-102567">Jonathan Bamber</a>, Professor of Physical Geography, <em><a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Floods, cyclones, thunderstorms: is climate change to blame for New Zealand’s summer of extreme weather?

<p>The final months of New Zealand’s summer carried a massive sting, bringing “unprecedented” rainfalls several times over, from widespread flooding in Auckland at the end of January to ex-tropical Cyclone Gabrielle dumping record rains and causing devastating floods across the east coast of the North Island.</p> <p>After all that, New Zealand experienced spells of thunderstorms, bringing repeat floods to parts of Auckland and then Gisborne.</p> <p>The obvious question is what role climate change plays in these record-breaking rainfalls.</p> <p>Some answers come from the international <a href="https://www.worldweatherattribution.org/">World Weather Attribution</a> team, which today released a <a href="https://spiral.imperial.ac.uk/bitstream/10044/1/102624/10/Scientific%20report%20New%20Zealand%20Floods.pdf">rapid assessment</a> which shows very heavy rain, like that associated with Cyclone Gabrielle, has become about four times more common in the region and extreme downpours now drop 30% more rain.</p> <p>The team analysed weather data from several stations, which show the observed increase in heavy rain. It then used computer models to compare the climate as it is today, after about 1.2℃ of global warming since the late 1800s, with the climate of the past.</p> <p>The small size of the analysed region meant the team could not quantify the extent to which human-caused warming is responsible for the observed increase in heavy rain in this part of New Zealand, but concluded it was the likely cause.</p> <h2>More energy in the atmosphere and ocean</h2> <p>Many factors add to the strength of a storm and the intensity of rainfall, especially for short bursts. A crucial factor is always the amount of energy available.</p> <p>Climate change is increasing that amount of energy in two main ways. First, everything is getting warmer. Rising sea surface temperatures provide <a href="https://sciencebrief.org/uploads/reviews/ScienceBrief_Review_CYCLONES_Mar2021.pdf">extra fuel for the development of tropical cyclones</a> because they grow by heating from below.</p> <p>Warmer seas mean potentially faster development of tropical cyclones, and stronger, more vigorous storms overall. Sea temperatures must be at least 26.5℃ to support the build-up of a tropical cyclone. So, as the oceans warm, these storms can reach farther from the equator.</p> <p>Second, warmer air can hold more water vapour. Every degree of warming increases the maximum amount of water vapour by around 7%. That extra water vapour tends to fall out as extra rain, but it also provides extra energy to a storm.</p> <h2>Driving waves further inland</h2> <p>The energy it takes to evaporate the water from the ocean surface and turn it into vapour is released again when the vapour condenses back into liquid water. A moister airmass heats the atmosphere more when clouds and rain form, making the air more buoyant and able to rise up more. This creates deeper, more vigorous clouds with stronger updrafts, and again more rain.</p> <p>Stronger updrafts in a storm mean more air will have to be drawn into the storm near the Earth’s surface, ensuring more “convergence” of air and moisture (water vapour). That’s why, even though a degree of warming translates to 7% more water vapour in the air, we can get 20% increases, or larger, in extreme rainfalls.</p> <p>All of this extra energy can contribute to making the storm stronger overall, with stronger winds and lower air pressures in its centre. This seems to have happened with Cyclone Gabrielle. Record low pressures were recorded at a few North Island locations as the storm passed.</p> <p>The low pressures act like a vacuum cleaner, sucking the sea surface up above normal sea level. The strong winds can then drive waves much further inland. Add in a bit of sea-level rise, and coastal inundation can get a lot worse a lot quicker.</p> <p>As the climate continues to change, storm intensity is likely to increase on average, as sea levels continue to rise. Those effects together are bound to lead to more dramatic coastal erosion and inundation.</p> <h2>Thunderstorms riding warming seas</h2> <p>These processes work for thunderstorms as well. A thunder cloud often starts as a buoyant mass of air over a warm surface. As the air rises (or convects), it cools and forces water vapour to condense back to liquid water, releasing heat and increasing the buoyancy and speed of the rising air.</p> <p>Again, that allows more moist air to be drawn into the cloud, and that convergence of moist air can increase rainfall amounts well above the 7% per degree of warming, for short bursts of very intense convection. The more intense the convection, the stronger the convergence of moisture and the heavier the resulting rainfall.</p> <p>Tropical cyclones have rings of thunderstorms around their eye during the time when they are truly tropical storms. As they transition out of the tropics into our neighbourhood, they change their structure but retain a lot of the moisture and buoyancy of the air. An ex-tropical cyclone like Gabrielle, moving over very warm water, can pack a devastating punch.</p> <p>Why has New Zealand had so much of this very heavy rain during the weeks from late January? Partly it’s the very warm ocean waters around Aotearoa (up to marine heatwave conditions) and farther north into the Coral Sea. That itself is partly related to the ongoing La Niña event in the tropical Pacific, which tends to pile up warm water (and tropical cyclones) in the west.</p> <p>But it is also related to ongoing global warming. As sea temperatures increase, it becomes easier to reach heatwave conditions. Warmer seas load the atmosphere with water vapour.</p> <p>Partly, too, the air over the North Island has been unusually “unstable” lately, very warm near ground level but cooler than normal higher up. That makes the buoyance in thunderstorms work even better and more strongly, encouraging very heavy rainfall.</p> <p>These conditions seem to have eased now, but severe thunderstorms continue to develop. As we move from summer into autumn, as the warmest seas move eastwards away from us and as La Niña fades in the tropics, the chances of a repeat event are diminishing. For now at least.</p> <p>But if we continue to warm the climate with more greenhouse gas emissions, we will continue to load the dice towards more very heavy rain over Aotearoa. Let us hope those regions and communities so badly affected by recent events have a chance to dry out, rebuild and recover before the next extreme weather.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/floods-cyclones-thunderstorms-is-climate-change-to-blame-for-new-zealands-summer-of-extreme-weather-201161" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

Is my medicine making me feel hotter this summer? 5 reasons why

<p>If you’re really feeling the heat this summer, it might be down to more than the temperature outside.</p> <p>Some types of medicines can increase your core body temperature or make you feel hotter than you really are. Some can affect your body’s ability to cool down.</p> <p>Here’s what you need to know about heat intolerance and medicines.</p> <h2>What is heat intolerance?</h2> <p>Some people simply dislike the feeling of feeling hot, while others feel hot at temperatures most people find comfortable. Both are examples of <a href="https://www.medicalnewstoday.com/articles/325232#symptoms">heat intolerance</a>.</p> <p>Typical symptoms during warm weather include excessive sweating (or not sweating enough), exhaustion and fatigue, nausea, vomiting or dizziness, and changes in mood.</p> <p>A number of factors can cause heat intolerance.</p> <p>This includes the disorder <a href="https://my.clevelandclinic.org/health/diseases/6004-dysautonomia">dysautonomia</a>, which affects people’s autonomic nervous system – the part of the body that regulates the automatic functions of the body, including our response to heat. </p> <p>Conditions such as diabetes, alcohol misuse, <a href="https://theconversation.com/what-causes-parkinsons-disease-what-we-know-dont-know-and-suspect-57579">Parkinson’s disease</a>, the autoimmune disease <a href="https://theconversation.com/explainer-what-is-guillain-barre-syndrome-and-is-it-caused-by-the-zika-virus-53884">Guillain-Barré syndrome</a> and <a href="https://theconversation.com/explainer-what-are-mitochondria-and-how-did-we-come-to-have-them-83106">mitochondrial disease</a> can cause dysautonomia. People in old age, those with some neurological conditions, or people less physically fit may also have it.</p> <p>But importantly, medications can also contribute to heat intolerance.</p> <h2>1. Your body temperature rises</h2> <p>Some medicines directly increase your body temperature, which then increases the risk of heat intolerance. </p> <p>These include <a href="https://bpspubs.onlinelibrary.wiley.com/doi/epdf/10.1111/bph.15465">stimulant medications</a> to treat ADHD (attention deficit hyperactivity disorder), such as methylphenidate, dexamfetamine and lisdexamfetamine.</p> <p><a href="https://www.healthdirect.gov.au/antipsychotic-medications">Antipsychotic medications</a> (such as clozapine, olanzapine and quetiapine) used to treat mental health conditions, such as schizophrenia and bipolar disorder, are other examples. </p> <p>These ADHD and antipsychotic medicines raise your temperature by acting on the hypothalamus, the region of the brain essential for cooling.</p> <p>The drug levothyroxine, used to treat an under-active thyroid, also increases your body temperature, this time by <a href="https://www.ncbi.nlm.nih.gov/books/NBK500006/">increasing your metabolism</a>.</p> <h2>2. Your blood flow is affected</h2> <p>Other medicines constrict (tighten) blood vessels, decreasing blood flow to the skin, and so prevent heat from escaping this way. This means your body can’t regulate its temperature as well in the heat. </p> <p>Examples include <a href="https://www.healthdirect.gov.au/beta-blockers">beta-blockers</a> (such as metoprolol, atenolol and propranolol). These medications are used to treat conditions such as high blood pressure, angina (a type of chest pain), tachycardia (fast heart rate), heart failure, and to prevent migraines. </p> <p><a href="https://www.nhs.uk/conditions/decongestants/">Decongestants</a> for blocked noses (for example, pseudoephedrine and phenylephrine), triptans for migraines (such as sumatriptan and zolmitriptan) and the ADHD medications mentioned earlier can also act to decrease blood flow to the skin.</p> <h2>3. You can get dehydrated</h2> <p>Other medicines can cause dehydration, which then makes you more susceptible to heat intolerance. The best examples are <a href="https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/diuretics/art-20048129">diuretics</a> such as furosemide, hydrochlorothiazide, acetazolamide and aldosterone.</p> <p>These are used to control high blood pressure and heart failure by forcing your kidneys to remove more fluid from your body. </p> <p>Laxatives, such as senna extract and bisacodyl, also remove water from your body and so have a similar effect.</p> <h2>4. You can sweat less</h2> <p>Other medicines have a drying effect. This can be needed for medicines to do their job (for instance, to dry up a runny nose). For others, it is an unwanted side effect. </p> <p>This drying reduces the amount you sweat, making it harder to lose heat and regulate your core temperature. A number of medicines have these effects, including:</p> <ul> <li>some antihistamines (such as promethazine, doxylamine and diphenhydramine)</li> <li>certain antidepressants (such as amitriptyline, clomipramine and dothiepin)</li> <li>medicines used to treat <a href="https://www.healthdirect.gov.au/urinary-incontinence#:%7E:text=Urinary%20incontinence%2C%20or%20poor%20bladder%20control%2C%20is%20very%20common%20in,to%20cure%20or%20improve%20it.">urinary incontinence</a> (for example, oxybutynin and solifenacin) </li> <li>nausea medicine (prochlorperazine)</li> <li>medicines for stomach cramps and spasms (for instance, hyoscine) </li> <li>the antipsychoptics chlorpromazine, olanzapine, quetiapine and clozapine.</li> </ul> <h2>5. You don’t feel thirsty</h2> <p>Finally, some medicines, such as the antipsychotics haloperidol and droperidol, can aggravate heat intolerance by reducing your ability to feel thirsty. </p> <p>If you don’t feel thirsty, you drink less and are therefore at risk of dehydration and feeling hot.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/is-my-medicine-making-me-feel-hotter-this-summer-5-reasons-why-199085" target="_blank" rel="noopener">The Conversation</a>. </em></p>

More than 100,000 tourists will head to Antarctica this summer. Should we worry about damage to the ice and its ecosystems?

<p>As the summer sun finally arrives for people in the Southern Hemisphere, more than 100,000 tourists will head for the ice. Travelling on one of more than 50 cruise ships, they will brave the two-day trip across the notoriously rough Drake Passage below Patagonia, destined for the polar continent of Antarctica. </p> <p>During the COVID summer of 2020-21, just 15 tourists on two yachts visited Antarctica. But now, tourism is back – and bigger than ever. This season’s <a href="https://iaato.org/wp-content/uploads/2022/06/ATCM44-IAATO-Overview.pdf">visitor numbers</a> are up more than 40% over the largest <a href="https://iaato.org/wp-content/uploads/2020/07/IAATO-on-Antarctic-visitor-figures-2019-20-FINAL.pdf">pre-pandemic year</a>. </p> <p>So are all those tourists going to damage what is often considered the last untouched wilderness on the planet? Yes and no. The industry is well run. Tourists often return with a new appreciation for wild places. They spend a surprisingly short amount of time actually on the continent or its islands. </p> <p>But as tourism grows, so will environmental impacts such as black carbon from cruise ship funnels. Tourists can carry in microbes, seed and other invasive species on their boots and clothes – a problem that will only worsen as ice melt creates new patches of bare earth. And cruise ships are hardly emissions misers.</p> <h2>How did Antarctic tourism go mainstream?</h2> <p>In the 1950s, the first tourists hitched rides on Chilean and Argentinian naval vessels heading south to resupply research bases on the South Shetland Islands. From the late 1960s, dedicated icebreaker expedition ships were venturing even further south. In the early 1990s, as ex-Soviet icebreakers became available, the industry began to expand – about a dozen companies offered trips at that time. By the turn of this century, the ice continent was receiving more than 10,000 annual visitors: Antarctic tourism had gone mainstream. </p> <p>What does it look like today? </p> <p>Most Antarctic tourists travel on small “expedition-style” vessels, usually heading for the relatively accessible Antarctic Peninsula. Once there, they can take a zodiac boat ride for a closer look at wildlife and icebergs or shore excursions to visit penguin or seal colonies. Visitors can kayak, paddle-board and take the polar plunge – a necessarily brief dip into subzero waters. </p> <p>For most tourists, accommodation, food and other services are provided aboard ship. Over a third of all visitors never stand on the continent. </p> <p>Those who do set foot on Antarctica normally make brief visits, rather than taking overnight stays. </p> <p>For more intrepid tourists, a few operators offer overland journeys into the continent’s interior, making use of temporary seasonal camp sites. There are no permanent hotels, and Antarctic Treaty nations recently <a href="https://documents.ats.aq/ATCM44/fr/ATCM44_fr001_e.pdf">adopted a resolution</a>against permanent tourist facilities. </p> <p>As tourists come in increasing numbers, some operators have moved to offer ever more adventurous options such as mountaineering, heli-skiing, underwater trips in submersibles and scuba diving.</p> <h2>Is Antarctic tourism sustainable?</h2> <p>As Antarctic tourism booms, some advocacy organisations have warned the impact may be unsustainable. For instance, the Antarctic and Southern Ocean Coalition <a href="https://www.asoc.org/campaign/responsible-tourism-and-shipping/">argues</a> cruise tourism could put increased pressure on an environment already under significant strain from climate change. </p> <p>In areas visited most by tourists, the snow has a <a href="https://theconversation.com/each-antarctic-tourist-effectively-melts-83-tonnes-of-snow-new-research-177597">higher concentration</a> of black carbon from ship exhaust, which soaks up more heat and leads to snow melt. Ship traffic also risks carrying <a href="https://www.pnas.org/doi/10.1073/pnas.2110303118">hitchhiking invasive species</a> into the Southern Ocean’s vulnerable marine ecosystems.</p> <p>That’s to say nothing of greenhouse gas emissions. Because of the continent’s remoteness, tourists visiting Antarctica have a <a href="https://www.tandfonline.com/doi/full/10.1080/09669581003653534">higher per capita carbon footprint</a>than other cruise-ship travellers. </p> <p>Of course, these impacts aren’t limited to tourism. Scientific expeditions come with similar environmental costs – and while there are far fewer of them, scientists and support personnel spend far more time on the continent. </p> <h2>Antarctic tourism isn’t going away – so we have to plan for the future</h2> <p>Are sustainable cruises an oxymoron? Many <a href="https://www.popsci.com/environment/why-cruise-ships-are-bad-for-the-environment/#:%7E:text=Studies%20have%20shown%20one%20cruise,in%20unhealthy%20levels%20of%20pollution.">believe so</a>. </p> <p>Through its sheer size, the cruise industry has created <a href="https://theconversation.com/time-to-rock-the-boat-cruise-ships-can-destroy-the-very-destinations-they-sell-to-us-55245">mass tourism</a> in new places and <a href="https://theconversation.com/overtourism-a-growing-global-problem-100029">overtourism</a> in others, generating unacceptable levels of crowding, disrupting the lives of residents, repurposing local cultures for “exotic” performances, damaging the environment and adding to emissions from fossil fuels. </p> <p>In Antarctica, crowding, environmental impact and emissions are the most pressing issues. While 100,000 tourists a year is tiny by global tourism standards – Paris had almost 20 million in 2019 – visits are concentrated in highly sensitive ecological areas for only a few months per year. There are no residents to disturb (other than local wildlife), but by the same token, there’s no host community to protest if visitor numbers get too high. </p> <p>Even so, strong protections are in place. In accordance with the Antarctic Treaty System – the set of international agreements signed by countries with an Antarctic presence or an interest – tourism operators based in those nations have to apply for permits and follow <a href="https://www.ats.aq/e/protocol.html">stringent environmental regulations</a>. </p> <p>To avoid introducing new species, tourists have to follow rules such as disinfecting their boots and vacuuming their pockets before setting foot on the ice, and keeping a set distance from wildlife. </p> <p>Almost all Antarctic cruise owners belong to the International Association of Antarctica Tour Operators, the peak body that manages Antarctic tourism. </p> <p>For the first time this year, operators have to report their <a href="https://iaato.org/antarctic-tour-operators-fuel-consumption-to-be-analysed-as-they-embark-on-climate-strategy/">overall fuel consumption</a> as part of IAATO’s efforts to make the industry more climate-friendly. Some operators are now using hybrid vessels that can run partly on electric propulsion for short periods, reducing carbon dioxide emissions.</p> <h2>Returning from the ice: the ambassador effect</h2> <p>Famed travel writer Pico Iyer <a href="https://www.nytimes.com/2022/11/17/t-magazine/travel-destinations-experiences.html?te=1&amp;nl=from-the-times&amp;emc=edit_ufn_20221127">recently wrote</a> of his experience in the deep south of the world.

The five best books to read by the pool this summer

<p>Australian literature is having a real moment, so here’s our pick of the best Australian novels to soak up with the sun this summer…</p> <p><strong>The Narrow Road to the Deep North, Richard Flanagan</strong></p> <p>It took Tasmanian author Richard Flanagan 12 years to write this Booker Prize-winning novel, and it’s easy to see why.</p> <p>Based on his father’s real-life experience, it’s a beautifully written, haunting read about a Japanese Prisoner of War camp on the Thai-Burma death railway during the Second World War.</p> <p>It focuses on Dorrigo Evans, an Australian surgeon haunted by a love affair with his uncle's young wife two years earlier, struggling to save the men under his command from starvation, cholera, and brutal beatings. </p> <p>At times the novel is harrowing, graphic and disturbing, but is ultimately a story of love in the midst of a cruel war.</p> <p><strong>The Light Between Oceans, M. L Stedman</strong></p> <p>Read this novel. We could just leave it there, to be honest, it’s that good.</p> <p>Hollywood movie rights were recently snapped up so, because books are nearly always better than subsequent films, read it quickly! It has won three prestigious ABIA awards, including their 'Book of the Year', and also won the Indie Awards' 'Book of the Year'.</p> <p> It’s 1926 and Tom Sherbourne is a young lighthouse keeper on a remote island off Western Australia. He and his young wife Isabel live a quiet life, cocooned from the rest of the world.</p> <p>Fatefully soon after suffering devastating miscarriages, a boat washes ashore carrying a dead man and a crying infant.</p> <p>Only years later do they discover the devastating consequences of the decision they made that day - as the baby's real story unfolds.</p> <p>Get your tissues ready. This book will stay with you for life. Promise.</p> <p><strong>The Night Guest, Fiona McFarlane</strong></p> <p>Fiona McFarlane’s debut novel has been shortlisted for the Stella prize and the Miles Franklin Award.</p> <p>One morning Ruth, an elderly widow, wakes thinking a tiger has been in her house in a small coastal town. Later that day a carer, Frida, arrives to look after her. Both Frida and the tiger are here to stay, and neither is what they seem.</p> <p>The Night Guest is a mesmerising novel about love, dependence, and the fear that the things you know best can become the things you're least certain about.</p> <p><strong>Eyrie, Tim Winton</strong></p> <p>Tim Winton’s 25<sup>th</sup> book follows Tom Keely, whose reputation is in ruins, whose marriage is over and career finished. Holed up in a grim high rise, cultivating his newfound isolation, he reluctantly meets a woman from his past and a boy who will change his life.</p> <p>Eyrie is heart-warming and human, and reassures the reader that no matter how low you can feel, life will renew itself and take new paths, whether you want it to or not. </p> <p><strong>The Swan Book, Alexis Wright</strong></p> <p>This is like nothing you’ve ever read before.</p> <p>Set in the future, around the time of Australia’s third centenary, we see Aboriginals still living under the Intervention in the north, in a country fundamentally altered by climate change.</p> <p>The book centres around the life of a mute young woman called Oblivia, the victim of gang-rape by petrol-sniffing youths. We follow her from the displaced community where she lives to her marriage to Warren Finch, the first Aboriginal president of Australia, and her elevation First Lady.</p> <p>Alexis Wright’s previous novel, <em>Carpentaria</em>, was a prize-winning best-seller and The Swan Book has been short-listed for the Miles Franklin Award. </p>

5 places in the world that have the best weather

<p>It’s just about the first question anyone asks you when you return from a holiday – “how was the weather?” It can make or break a holiday. These are the places you should go if you want to leave the wellies at home.</p> <p><strong>Los Angeles</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/los-angeles.jpg" alt="" width="1280" height="720" /><br /></strong></p> <p>California is a pretty safe bet all round and has easily the best weather in the USA. You can expect “perfect” days for close to half the year. That means an average temperature between 12 and 23 degrees Celsius, and temperatures that never fall below seven degrees or rise above 30. And on top of that there’s almost no rain. Sounds pretty good to us.</p> <p><strong>Canary Islands</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/canary-islands2.jpg" alt="" width="1280" height="720" /><br /></strong></p> <p>This island group off the northern coast of West Africa is technically a Spanish territory and a popular holiday spot for the Brits. With an average temperature of 22 degrees Celsius all year round and no extremes of hot or cold, the Canaries claim to have the best climate in the world. The capital, Gran Canaria, gets a minimum of six hours of sunshine per day in winter and up to almost eight hours in summer. Plenty of time then to indulge in a round of golf – there are eight world-class courses on the island.</p> <p><strong>Sao Paulo</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/sao-paulo.jpg" alt="" width="1280" height="720" /><br /></strong></p> <p>Whatever time of year you visit Brazil’s largest city, you probably won’t need to bring a jacket. Even in the middle of winter (July or August) temperatures rarely get below 20 degrees and they don’t rise much over 30 in summer. It can be rainy, but the city rarely gets big storms. Its inland location and high elevation work together to create a perfect microclimate. This is in contrast to the coastal city of Rio de Janeiro, just 400 kilometres away, which swelters through the hotter months.</p> <p><strong>Lisbon</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/lisbon.jpg" alt="" width="1280" height="720" /><br /></strong></p> <p>The Portuguese capital sits on the Atlantic coast, which moderates its weather and helps it avoid the uncomfortably hot summers that you’ll find in many other European capitals. Lisbon gets around 30 inches of rain each year but the majority of this falls during winter, so you’re likely to get weeks on end of pure sunshine in the summer months.</p> <p><strong>Sydney</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/opera-house7.jpg" alt="" width="1280" height="720" /><br /></strong></p> <p>Despite Australia having some of the most extreme weather in the world, Sydney is famous for its dry summers, mild winters and endless hours of sparkling sunshine. Even a run of cold days is quickly forgotten when the harbour city turns on a warm, sunny August afternoon.</p> <p><em>Images: Getty Images</em></p>

Why mozzies bite some more than others

<p dir="ltr">While summer brings with it days on the beach and nights outside enjoying the balmy weather, another, more unpleasant summer fixture also comes out in droves: mosquitoes.</p> <p dir="ltr">Although some of us dread being covered in itchy bites, there are others who mosquitoes seem to ignore - and now scientists have part of the answer explaining why.</p> <p dir="ltr">Researchers from Rockefeller University have found that mosquitoes are attracted to people based on the smell of their skin, created through a blend of particular acids.</p> <p dir="ltr">Focusing on Aedes aegypti, the mosquito which carries viruses such as dengue, yellow fever and Zika virus, the team used samples of human forearm odour collected on nylon stockings from 64 people, performing more than 2300 tests over 174 days across a three-year study.</p> <p dir="ltr">They found that people who were highly attractive to the mosquitoes had significantly higher levels of carboxylic acids which contribute to their skin odour.</p> <p dir="ltr">These carboxylic acids are produced when bacteria on the skin breaks down steroids and cholesterol secreted by our sweat glands.</p> <p dir="ltr">"We tested mosquito attraction to human skin odour and identified people who are exceptionally attractive or unattractive to mosquitoes," they wrote.</p> <p dir="ltr">"Chemical analysis revealed that highly attractive people produce significantly more carboxylic acids in their skin [than others]."</p> <p dir="ltr">They also noted that there weren’t any chemicals found in higher levels on the skin of less attractive people and argued that this supports the idea that people’s skin lack attractive odours, rather than emitting an odour that repels mosquitoes.</p> <p dir="ltr">As for why some people have higher levels of these chemicals in their skin odour than others, the researchers suggested that genetics may play a role.</p> <p dir="ltr">"Understanding why some humans are more attractive than others provides insights into what skin odorants are most important to the mosquito and could inform the development of more effective ... repellents," they wrote.</p> <p dir="ltr">The study, published in the journal <em><a href="https://doi.org/10.1016/j.cell.2022.09.034" target="_blank" rel="noopener">Cell</a></em>, isn’t the first time scientists have attempted to understand why some people are more attractive to mozzies than others - and there are plenty of reasons why.</p> <p dir="ltr">Mosquito researcher Dr Cameron Webb from the University of Sydney told the <em><a href="https://www.abc.net.au/news/2022-10-19/nt-mosquitoes-study/101548550" target="_blank" rel="noopener">ABC</a></em> it could be to do with genetics, as well as your temperature, your diet, whether you’re sweaty or even whether you’re pregnant.</p> <p dir="ltr">Dr Gordana Rasic, a senior mosquito research officer at QIMR Berghofer Medical Research Institute in Queensland, explained that the factors driving the behaviour of mozzies are “very complex”.</p> <p dir="ltr">"Mosquito brains are small but they still process signals from hundreds and hundreds of different receptors," she said. </p> <p dir="ltr">"Biting humans is specific to female mosquitoes — they need to bite humans and take blood in order to develop their egg and basically reproduce — so it's an absolutely essential instinct."</p> <p dir="ltr">While this study adds a new piece to the puzzle of mozzie behaviour, Dr Webb noted that this study focused on one mosquito species out of thousands of species around the world.</p> <p dir="ltr">"Even if you solve the problem for one mosquito, that doesn't mean the relationship and their willingness to bite people applies to all of the mozzies," he said. </p> <p><span id="docs-internal-guid-07911092-7fff-f285-028e-94767fc3f8aa"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Lady Louise Windsor has surprising new job

<p dir="ltr">Lady Louise Windsor, one of Queen Elizabeth’s numerous grandchildren, has joined the thousands of young people in a tradition as old as time itself: getting a summer job.</p> <p dir="ltr">Though she might be a royal, the 18-year-old’s new job is quite ordinary, with reports that she is earning £6.83 ($AU 11.68 or $NZ 13.03) at a garden centre.</p> <p dir="ltr">According to <em>The Sun</em>, Lady Louise was spotted by a shopper, pruning and potting plants, as well as greeting customers and serving them behind the till.</p> <p dir="ltr">The shopper described the daughter of Prince Edward and Sophie, the Countess of Wessex, as “modest”, “sweet” and “polite”.</p> <p dir="ltr">“I couldn’t believe it was Lady Louise – I had to look twice,” the shopper told the newspaper.</p> <p dir="ltr">“She is a really modest and sweet young woman who is polite and attentive to customers. She seemed to be loving the job.</p> <p dir="ltr">“You’d never imagine the Queen’s granddaughter would take on a role working behind a till.”</p> <p dir="ltr">It’s believed Lady Louise is working at the garden centre several days a week, with the news coming after a Buckingham Palace spokesperson confirmed she would be studying English at the University of St Andrew’s after finishing her A-levels in June.</p> <p dir="ltr">Though she is 16th in line for the throne, Lady Louise and her brother, James, don’t use an HRH title, nor are they expected to carry out duties when they’re older.</p> <p dir="ltr">As unexpected as the royal’s job appears, it seems to have delighted fans of the monarchy, with one fan telling <em>The Sun</em>: “It’s not every day you buy begonias off a royal.”</p> <p><span id="docs-internal-guid-40e9b517-7fff-cd84-bd70-3ee69a7e173c"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

Model’s tiny mole turns out to be cancer

<p dir="ltr">A model who completely disregarded what she thought was a mole on her ankle has been diagnosed with cancer. </p> <p dir="ltr">Oceana Strachan would regularly get her skin checked to ensure she was safe from melanoma and was constantly given the green light. </p> <p dir="ltr">But she knew something was wrong when the tiny mark on her ankle was itchy and had risen a bit - raising the alarm as to whether or not it was something else. </p> <p dir="ltr">Doctors dismissed it as a mole but Oceana pushed for a biopsy to be done and it was found to be stage two melanoma. </p> <p dir="ltr">“My melanoma spot looked like a regular mole but I noticed changes like itching that raised a red flag for me,” she told <a href="https://7news.com.au/lifestyle/health-wellbeing/aussie-model-shares-warning-signs-after-tiny-find-led-to-sinister-diagnosis-c-6840204" target="_blank" rel="noopener">7News</a>.</p> <p dir="ltr">“Going through melanoma, I didn’t know if I was going to survive.

Three unconventional forms of travel you should try if you can’t go abroad this summer

<p>There has never been a better time to rethink the traditional vacation. International tourism <a href="https://unctad.org/news/global-economy-could-lose-over-4-trillion-due-covid-19-impact-tourism" target="_blank" rel="noopener">has been decimated</a> by the pandemic, and it is likely <a href="https://www.spglobal.com/ratings/en/research/articles/210624-economic-research-asia-pacific-s-recovery-regains-its-footing-12010263" target="_blank" rel="noopener">to be difficult</a> for the travel industry to recover in the near future.</p><p>Short-term, uncertainty around leisure travel continues. COVID-19 restrictions have limited international travel opportunities to a confusing patchwork of <a href="https://www.gov.uk/guidance/red-amber-and-green-list-rules-for-entering-england" target="_blank" rel="noopener">recommendations</a> and <a href="https://www.cdc.gov/coronavirus/2019-ncov/travelers/from-other-countries.html" target="_blank" rel="noopener">restrictions</a>. Tourists travelling for Euro 2020 have been linked to <a href="https://www.reuters.com/world/europe/who-warns-third-coronavirus-wave-europe-2021-07-01/" target="_blank" rel="noopener">spikes in COVID-19 cases</a>. Australia has re-imposed regulations on domestic and international travel to try and manage the virus’s spread.</p><p>Long-term, we need to make tourism more sustainable. Aviation contributes <a href="https://www.bbc.com/future/article/20200218-climate-change-how-to-cut-your-carbon-emissions-when-flying" target="_blank" rel="noopener">around 5%</a> of annual human-made global warming. Tourism also needs to be more inclusive. In the UK, just 1% of the population take <a href="https://policy.friendsoftheearth.uk/policy-positions/aviation-and-climate-change-our-position" target="_blank" rel="noopener">20% of flights abroad</a>.</p><p>Given this situation, familiar assumptions about what vacations should look like are overdue a reset. Our current model contributes to climate change. It confines the benefits of tourism to a few positives, while the negative impacts are felt by many. And it may be unavailable for the foreseeable future.</p><p>Alternative tourism approaches are available, however. But rather than being about money, they focus on mindset. They are the ways in which philosophy can help us to rethink tourism and explore options which may be more accessible and sustainable to us overall.</p><p>Tourism is something that takes us <a href="https://www.unwto.org/glossary-tourism-terms" target="_blank" rel="noopener">out of the usual</a>. Stepping outside of everyday routines gives us a chance to relax. Doing something unfamiliar provides opportunities to learn. But you don’t need to travel long distances to reap the benefits. We can access the unfamiliar close to home:</p><p><strong>Micro-domestic tourism</strong></p><p>This refers to tourism that takes place within a confined space. This might be <a href="https://journals.sagepub.com/doi/pdf/10.1177/0047287512467700?casa_token=a14z3S6HohsAAAAA:kq0-81ZjUqvQbkNHNpdrPmP6NDQqsp1-hUfaGlVTW5Z5tvX5t61AK9t0RtboR6hAPHZ0MFdxi-4E" target="_blank" rel="noopener">inhabitants of small islands</a> taking a trip from one side to another, for example. Or even visiting a holiday home that is <a href="https://www.sciencedirect.com/science/article/abs/pii/0160738386900265" target="_blank" rel="noopener">in sight of your main house</a>. Even tiny journeys can take you into an entirely different headspace.</p><p>Somewhere close by can be unfamiliar. A particular footpath never followed, or an unknown part of town. Entering such spaces provides the chance to leave behind the accustomed. It gives people the change to relax, rethink, and reconnect with themselves and others. Psychological rather than geographic distance is what counts.</p><figure class="align-center "><img src="https://images.theconversation.com/files/409917/original/file-20210706-13-tvpryb.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Silhouettes of people making shapes by a light in a tent at night" /><figcaption><em><span class="caption">Somewhere close by can be unfamiliar.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/silhouettes-children-playing-camping-tent-night-1629935020" target="_blank" rel="noopener">Dmitry Naumov/Shutterstock</a></span></em></figcaption></figure><p><strong>Virtual travel</strong></p><p>It may even be possible to take a vacation <a href="https://www.bbc.com/travel/article/20200330-covid-19-virtual-travel-during-coronavirus" target="_blank" rel="noopener">without leaving the house</a>.

This means following the flow of whatever landscape you’re in with no particular purpose. The idea is to see what interests you on the day, following those instincts, and finding out where they take you. Wandering and wondering can lead to surprising places.

Psychogeography, meanwhile, encourages us to re-engage with physical, and perhaps digital, spaces that are taken for granted.

Game-based <a href="https://www.shortlist.com/news/video-game-travel-guide" target="_blank" rel="noopener">holiday hotspots</a> have long been known to fans.
