Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<p><em><a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a></em></p> <p>Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike.</p> <p>Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog.</p> <p>I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets.</p> <h2>Breed and age differences</h2> <p>Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia.</p> <p>Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat.</p> <p>Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather.</p> <h2>When is my dog too cold?</h2> <p>Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable.</p> <p>Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>.</p> <p>Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog.</p> <p>Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it.</p> <h2>Road salt dangers</h2> <p>Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws.</p> <p>Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs.</p> <p>Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation.</p> <h2>Antifreeze risks</h2> <p><a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing.</p> <p>Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>.</p> <p>There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment.</p> <p>When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time.</p> <p>Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<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/221709/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, Health Sciences Assistant Professor of Clinical Veterinary Medicine, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</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.

"Do you hear it?": Worldwide hum global mystery baffles scientists

<p>A perplexing phenomenon known as "The Worldwide Hum" has been capturing the attention of scientists and citizens alike, as an unusual low-frequency noise continues to puzzle experts.</p> <p>This mysterious hum, first recorded in 2012, has been reported by thousands of people worldwide, sparking investigations, online discussions and even <a href="https://www.thehum.info/" target="_blank" rel="noopener">the creation of an interactive map</a> documenting instances of the enigmatic sound. As researchers strive to unravel the mystery, individuals share their experiences, raising questions about its origin and effects.</p> <p>Described as a low rumbling or droning sound, "the hum" is often likened to the idling of a car or truck engine. What makes this phenomenon particularly intriguing is that it is not universally heard, with reports of the hum being exclusive to certain individuals.</p> <p>Some claim it is more pronounced at night than during the day, and louder indoors than outdoors. One Reddit user even compared it to the low-frequency vibrations felt when a passenger jet flies overhead.</p> <p>Since its first documentation, more than 6,500 instances of the hum have been reported globally, with new cases continually emerging. The interactive user-generated World Hum Map and Database Project <span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">captures the experiences of those who have encountered the sound, providing a comprehensive overview of its widespread occurrence. In some regions, authorities such as the Environment Protection Authority (EPA) have conducted investigations, as was the case in the NSW Waverley Council ten years ago. Despite these efforts, the source of the hum remains elusive.</span></p> <p>Individuals affected by the mysterious noise often find solace in online communities, where they share their experiences and discuss possible explanations. Some describe feeling as though they are "going insane", and say that the psychological impact of the persistent hum is actually very severe.</p> <p>Facebook support groups have become a platform for individuals to connect, share anecdotes and speculate about the origin of the sound. Theories range from the mundane – such as the use of headphones causing collective tinnitus – to more complex environmental factors.</p> <p>While tinnitus, a symptom of auditory system issues, has been proposed as a potential explanation, it does not account for the collective experience of the hum. Various theories, including industrial plants, ocean waves, lightning strikes and the proliferation of mobile phone towers, have been suggested over the years. However, none of these explanations have gained widespread acceptance or provided a conclusive answer.</p> <p>Dr Glen MacPherson, who initiated the World Hum Map and Database Project, experienced the hum firsthand on Canada's Sunshine Coast. Having debunked the idea of "hum hotspots", Dr MacPherson theorises that the hum may be a subjective phenomenon, akin to tinnitus, originating from within the individual rather than an external source. His 11 years of research highlight the complexity of the mystery, challenging initial assumptions and pointing towards the need for further investigation.</p> <p>As "The Worldwide Hum" continues to captivate the curiosity of scientists and citizens worldwide, the quest for understanding remains elusive. While theories abound, the true origin of the hum remains unknown, leaving both experts and individuals alike intrigued by a phenomenon that transcends geographic boundaries and defies conventional explanations.</p> <p><em>Image: Getty</em></p>

Will we still have antibiotics in 50 years? We asked 7 global experts

<p>Almost since antibiotics were <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937522/#:%7E:text=Since%20the%20introduction%20in%201937,operate%20some%2070%20years%20later.">first discovered</a>, we’ve been aware bacteria can learn how to overcome these medicines, a phenomenon known as antimicrobial resistance.</p> <p>The World Health Organization says we’re currently <a href="https://www.who.int/news/item/20-09-2017-the-world-is-running-out-of-antibiotics-who-report-confirms">losing to the bugs</a>, with resistance increasing and too few new antibiotics in the pipeline. </p> <p>We wanted to know whether experts around the world think we will still have effective antibiotics in 50 years. Seven out of seven experts said yes.</p> <p><strong>Lori Burrows - Biochemist, Canada</strong></p> <p>Yes! Antibiotics are a crucial component of modern medicine, and we can't afford to lose them. Despite the rise of resistance in important pathogens (bugs), and the substantial decrease in new drugs in development, we have multiple tools at our disposal to protect antibiotics. Stewardship - the principle of using antibiotics only when absolutely necessary - is key to maintaining the usefulness of current antibiotics and preventing resistance to new drugs from arising. New diagnostics, such as the rapid tests that became widely available during the pandemic, can inform stewardship efforts, reducing inappropriate antibiotic use for viral diseases. </p> <p>Finally, researchers continue to find creative ways, including the use of powerful artificial intelligence approaches, to identify antimicrobial compounds with new targets or new modes of action. Other promising tactics include using viruses that naturally kill bacteria, stimulating the host's immune system to fight the bacteria, or combining existing antibiotics with molecules that can enhance antibiotic activity by, for example, increasing uptake or blocking resistance.</p> <p><strong>André Hudson - Biochemist, United States</strong></p> <p>Yes. The real question is not whether we will have antibiotics 50 years from now, but what form of antibiotics will be used. Most antibiotics we use today are modelled after natural products isolated from organisms such as fungi and plants. The use of <a href="https://news.mit.edu/2020/artificial-intelligence-identifies-new-antibiotic-0220">AI</a>, machine learning, and other <a href="https://www.theguardian.com/technology/2023/may/25/artificial-intelligence-antibiotic-deadly-superbug-hospital">computational tools</a> to help design novel, unnatural compounds that can circumvent the evolution of antibiotic resistance are only in the very early stages of development. </p> <p>Many of the traditional medicines such as penicillins and other common antibiotics of today which are already waning in efficacy, will probably be of very little use in 50 years. Over time, with the aid of new technology, I predict we will have new medicines to fight bacterial infections.</p> <p><strong>Ray Robins-Browne - Microbiologist, Australia</strong></p> <p>Yes, we will have antibiotics (by which I mean antimicrobial drugs), because people will still get infections despite advances in immunisation and other forms of prevention. Having said this, drugs of the future will be quite different from those we use today, which will have become obsolete well within the next 50 years. The new drugs will have a narrow spectrum, meaning they will be targeted directly at the specific cause of the infection, which we will determine by using rapid, point-of-care diagnostic tests, similar to the RATS we currently use to diagnose COVID. </p> <p>Antimicrobials of the future won’t kill bacteria or limit their growth, because this encourages the development of resistance. Instead, they will limit the ability of the bacteria to cause disease or evade our immune systems.</p> <p><strong>Raúl Rivas González - Microbiologist, Spain</strong></p> <p>Yes, but not without effort. Currently, antimicrobial resistance is a leading cause of death globally, and will continue to rise. But in my opinion, there will still be useful antibiotics to combat bacterial infections within 50 years. To achieve this, innovation and investment is required. Artificial intelligence may even be able to help. An example is the compound "RS102895", which eliminates the multi-resistant superbug Acinetobacter baumannii. This was identified through a machine learning algorithm. </p> <p>The future of antibiotics requires substantial changes in the search for new active molecules and in the design of therapies that can eliminate bacteria without developing resistance. We are on the right path. An example is the discovery of clovibactin, recently isolated from uncultured soil bacteria. Clovibactin effectively kills antibiotic-resistant gram-positive bacteria without generating detectable resistance. Future antimicrobial therapy may consist of new antibiotics, viruses that kill bacteria, specific antibodies, drugs that counter antibiotic resistance, and other new technology.</p> <p><strong>Fidelma Fitzpatrick - Microbiologist, United Kingdom</strong></p> <p>Yes, but not many. Without rapid scale-up of measures to curtail the "<a href="https://www.oecd.org/health/embracing-a-one-health-framework-to-fight-antimicrobial-resistance-ce44c755-en.htm">alarming global health threat</a>" of antimicrobial resistance by 2073, there will be few effective antibiotics left to treat sepsis. The <a href="https://www.cdc.gov/drugresistance/covid19.html">Centre for Disease Control</a> has indicated a reversal of progress following the pandemic, when all focus in healthcare, government and society was on COVID. Without an approach targeting people, animals, agri-food systems and the environment, antimicrobial resistance will continue its upward trajectory. <a href="https://www.worldbank.org/en/topic/health/publication/drug-resistant-infections-a-threat-to-our-economic-future">Doing nothing</a> is unacceptable – lives will be lost, healthcare expenditure will increase and workforce productivity will suffer. </p> <p>The highest burden of antimicrobial resistance is in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">low-income countries</a>. <a href="https://www.ncbi.nlm.nih.gov/books/NBK543407/">Action plans</a> exist in most OECD, European and G20 countries. In all countries plans need to be funded and implemented across all relevant sectors as above. Better integrated data to track antibiotic use and resistance across human and animal health and the environment, in addition to research and development for new antibiotics, vaccines and diagnostics, will be necessary.</p> <p><strong>Juliana Côrrea - Public health expert, Brazil </strong></p> <p>Yes. However, <a href="https://www.sciencedirect.com/science/article/pii/S0188440905002730?via%3Dihub">available data</a> suggest that without a shift in the political agenda towards the control and prevention of antimicrobial resistance, several antibiotics will have lost their utility. The problem of bacterial resistance is not new and the risk of antibiotics becoming ineffective in the face of the evolutionary capacity of bacteria is one of the main problems facing global health. The creation of policies to promote the appropriate use of this resource has not progressed at the same speed as inappropriate use in human and animal health and in agricultural production. </p> <p>The factors that impact antibiotic use are complex and vary according to local contexts. The response to the problem goes far beyond controlling use at the individual level. We must recognise the social, political, and economic dimensions in proposing more effective governance.</p> <p><strong>Yori Yuliandra -  Pharmacist, Indonesia</strong></p> <p>Yes. Despite their <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">reduced efficacy over time</a>, antibiotics continue to be produced every year. Researchers are tirelessly working to develop new and more effective antibiotics. And researchers are actively exploring combinations of antibiotics to enhance their efficacy. While antimicrobial resistance is rising, researchers have been making remarkable progress in addressing this issue. They have developed innovative antibiotic classes such as <a href="https://doi.org/10.4155/fmc-2016-0041">FtsZ inhibitors</a> which can inhibit cell division, a process necessary for bacteria to multiply. <a href="https://www.who.int/publications/i/item/9789240021303">Clinical trials</a> are currently taking place.</p> <p>A deeper understanding of the molecular aspects of bacterial resistance has led to the discovery of new treatment strategies, such as the <a href="https://doi.org/10.1039/D2MD00263A">inhibition of key enzymes</a> that play a pivotal role in bugs becoming resistant. And <a href="https://doi.org/10.1038/s42003-021-02586-0">advances in computer technology</a> have greatly accelerated drug discovery and development efforts, offering hope for the rapid discovery of new antibiotics and treatment strategies.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/will-we-still-have-antibiotics-in-50-years-we-asked-7-global-experts-214950" target="_blank" rel="noopener">The Conversation</a>. </em></p>

6 reasons why global temperatures are spiking right now

<p><em><a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>The world is very warm right now. We’re not only seeing record temperatures, but the records are being broken by record-wide margins.</p> <p>Take the preliminary September global-average temperature anomaly of 1.7°C above pre-industrial levels, for example. It’s an incredible 0.5°C above the previous record.</p> <p>So why is the world so incredibly hot right now? And what does it mean for keeping our Paris Agreement targets?</p> <p>Here are six contributing factors – with climate change the main reason temperatures are so high.</p> <h2>1. El Niño</h2> <p>One reason for the exceptional heat is we are in a <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean">significant El Niño</a> that is still strengthening. During El Niño we see warming of the surface ocean over much of the tropical Pacific. This warming, and the effects of El Niño in other parts of the world, raises global average temperatures by <a href="https://www.realclimate.org/index.php/archives/2023/01/2022-updates-to-the-temperature-records/">about 0.1 to 0.2°C</a>.</p> <p>Taking into account the fact we’ve just come out of a triple La Niña, which cools global average temperatures slightly, and the fact this is the first major El Niño in eight years, it’s not too surprising we’re seeing unusually high temperatures at the moment.</p> <p>Still, El Niño alone isn’t enough to explain the crazily high temperatures the world is experiencing.</p> <h2>2. Falling pollution</h2> <p>Air pollution from human activities cools the planet and has offset some of the warming caused by humanity’s greenhouse gas emissions. There have been efforts to reduce this pollution – since 2020 there has been an <a href="https://sdg.iisd.org/news/imo-advances-measures-to-reduce-emissions-from-international-shipping/">international agreement</a> to reduce sulphur dioxide emissions from the global shipping industry.</p> <p>It has been speculated this cleaner air has contributed to the recent heat, particularly over the record-warm <a href="https://climate.copernicus.eu/record-breaking-north-atlantic-ocean-temperatures-contribute-extreme-marine-heatwaves">north Atlantic</a> and Pacific regions with high shipping traffic.</p> <p>It’s likely this is contributing to the extreme high global temperatures – but only on the order of hundredths of a degree. <a href="https://www.carbonbrief.org/analysis-how-low-sulphur-shipping-rules-are-affecting-global-warming/">Recent analysis</a> suggests the effect of the 2020 shipping agreement is about an extra 0.05°C warming by 2050.</p> <h2>3. Increasing solar activity</h2> <p>While falling pollution levels mean more of the Sun’s energy reaches Earth’s surface, the amount of the energy the Sun emits is itself variable. There are different solar cycles, but an 11-year cycle is the most relevant one to today’s climate.</p> <p>The Sun is becoming <a href="https://edition.cnn.com/2023/07/14/world/solar-maximum-activity-2024-scn/index.html">more active</a> from a minimum in late 2019. This is also contributing a small amount to the spike in global temperatures. Overall, increasing solar activity is contributing only hundredths of a degree at most to the recent global heat.</p> <h2>4. Water vapour from Hunga Tonga eruption</h2> <p>On January 15 2022 the underwater <a href="https://www.jpl.nasa.gov/images/pia26006-hunga-tonga-hunga-haapai-eruption">Hunga Tonga–Hunga Haʻapai volcano erupted</a> in the South Pacific Ocean, sending large amounts of water vapour high up into the upper atmosphere. Water vapour is a greenhouse gas, so increasing its concentration in the atmosphere in this way does intensify the greenhouse effect.</p> <p>Even though the eruption happened almost two years ago, it’s still having a small warming effect on the planet. However, as with the reduced pollution and increasing solar activity, we’re talking about hundredths of a degree.</p> <figure><iframe src="https://www.youtube.com/embed/6oANPi-SWN0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>5. Bad luck</h2> <p>We see variability in global temperatures from one year to the next even without factors like El Niño or major changes in pollution. Part of the reason this September was so extreme was likely due to weather systems being in the right place to heat the land surface.</p> <p>When we have persistent high-pressure systems over land regions, as seen recently over places like <a href="https://www.theguardian.com/environment/2023/oct/01/autumn-heat-continues-in-europe-after-record-breaking-september">western Europe</a> and <a href="https://www.abc.net.au/news/2023-09-19/australia-weather-september-heat-records-tumble/102870294">Australia</a>, we see local temperatures rise and the conditions for unseasonable heat.</p> <p>As water requires more energy to warm and the ocean moves around, we don’t see the same quick response in temperatures over the seas when we have high-pressure systems.</p> <p>The positioning of weather systems warming up many land areas coupled with persistent ocean heat is likely a contributor to the global-average heat too.</p> <h2>6. Climate change</h2> <p>By far the biggest contributor to the overall +1.7°C global temperature anomaly is human-caused climate change. Overall, humanity’s effect on the climate has been a global warming of <a href="https://www.globalwarmingindex.org/">about 1.2°C</a>.</p> <p>The record-high rate of greenhouse gas emissions means we should expect global warming to accelerate too.</p> <p>While humanity’s greenhouse gas emissions explain the trend seen in September temperatures over many decades, they don’t really explain the big difference from last September (when the greenhouse effect was almost as strong as it is today) and September 2023.</p> <p>Much of the difference between this year and last comes back to the switch from La Niña to El Niño, and the right weather systems in the right place at the right time.</p> <h2>The upshot: we need to accelerate climate action</h2> <p>September 2023 shows that with a combination of climate change and other factors aligning we can see alarmingly high temperatures.</p> <p>These anomalies may appear to be above the 1.5°C global warming level referred to in the Paris Agreement, but that’s about keeping <a href="https://climateanalytics.org/briefings/understanding-the-paris-agreements-long-term-temperature-goal/">long-term global warming</a> to low levels and not individual months of heat.</p> <p>But we are seeing the effects of climate change unfolding more and more clearly.</p> <p>The most vulnerable are suffering the biggest impacts as wealthier nations continue to emit the largest proportion of greenhouse gases. Humanity must accelerate the path to net zero to prevent more record-shattering global temperatures and damaging extreme events.<!-- Below is The Conversation's page counter tag.

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.

Research reveals who’s been hit hardest by global warming in their lifetime - and the answer may surprise you

We’ve seen it in the past few weeks as temperatures hit record highs around the world – both in the Northern Hemisphere and the <a href="https://theconversation.com/why-is-australia-having-such-a-warm-winter-a-climate-expert-explains-210693">warm Australian winter</a>.</p> <p>Global warming is caused by humanity’s greenhouse gas emissions, which continue at <a href="https://theconversation.com/global-carbon-emissions-at-record-levels-with-no-signs-of-shrinking-new-data-shows-humanity-has-a-monumental-task-ahead-193108">near-record pace</a>. These emissions are predominantly generated by people in the world’s wealthiest regions.</p> <p>Our world-first analysis, <a href="https://iopscience.iop.org/article/10.1088/2752-5295/aceff2">published today</a>, examines the experience of global warming over the lifetimes of people around the world: young and old, rich and poor. We sought to identify who has perceived warmer temperatures most keenly.</p> <p>We found middle-aged people in equatorial regions have lived through the most perceptible warming in their lifetimes. But many young people in lower-income countries could experience unrecognisable changes in their local climate later in life, unless the world rapidly tackles climate change.</p> <h2>Measuring the climate change experience</h2> <p>We examined temperature data and population demographics information from around the world.</p> <p>Key to our analysis was the fact that not all warming is due to human activity. Some of it is caused by natural, year-to-year variations in Earth’s climate.</p> <p>These natural ups and downs are due to a number of factors. They include variations in the energy Earth receives from the sun, the effects of volcanic eruptions, and transfers of heat between the atmosphere and the ocean.</p> <p>This variability is stronger in mid-to-high-latitude parts of the world (those further from the equator) than in low-latitude areas (in equatorial regions). That’s because the weather systems further away from the equator draw in hot or cold air from neighbouring areas, but equatorial areas don’t receive cold air at all.</p> <p>That’s why, for example, the annual average temperature in New York is naturally more variable than in the city of Kinshasa (in the Democratic Republic of Congo).</p> <p>To account for this, we applied what’s known as the “<a href="https://archive.ipcc.ch/ipccreports/tar/wg1/346.htm#:%7E:text=The%20%EF%BF%BDsignal%20to%20noise,to%20this%20natural%20variability%20noise.">signal-to-noise ratio</a>” at each location we studied. That allowed us to separate the strength of the climate change “signal” from the “noise” of natural variability.</p> <p>Making this distinction is important. The less naturally variable the temperature, the clearer the effects of warming. So warming in Kinshasa over the past 50 years has been much more perceptible than in New York.</p> <p>Our study examined two central questions. First, we wanted to know, for every location in the world, how clearly global warming could be perceived, relative to natural temperature variability.</p> <p>Second, we wanted to know where this perceived change was most clear over human lifetimes.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.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/541474/original/file-20230807-17-ogjdti.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/541474/original/file-20230807-17-ogjdti.png?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/541474/original/file-20230807-17-ogjdti.png?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/541474/original/file-20230807-17-ogjdti.png?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/541474/original/file-20230807-17-ogjdti.png?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/541474/original/file-20230807-17-ogjdti.png?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/541474/original/file-20230807-17-ogjdti.png?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="Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021." /></a><figcaption><span class="caption">Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021.</span> <span class="attribution"><span class="source">Author provided</span></span></figcaption></figure> <h2>Our results</h2> <p>So what did we find? As expected, the most perceptible warming is found in tropical regions – those near the equator. This includes developing parts of the world that constitute the Global South – such as Africa, Latin America and the Caribbean, and Asia.</p> <p>Household incomes in the Global South are typically lower than in industrialised nations (known as the Global North). We might, then, conclude people in the poorest parts of the world have experienced the most perceptible global warming over their lifetimes. But that’s not always the case.</p> <p>Why? Because most parts of the Global South have younger populations than wealthier regions. And some people under the age of 20, including in northern India and parts of Sub-Saharan Africa, haven’t experienced warming over their lifetimes.</p> <p>In these places, the lack of recent warming is likely down to a few factors: natural climate variability, and the local cooling effect of particles released into the atmosphere from <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac3b7a">pollution</a> and changes in land use.</p> <p>There’s another complication. Some populated regions of the world also experienced slight cooling in the mid-20th century, primarily driven by human-caused <a href="https://www.nature.com/articles/nature10946">aerosol emissions</a>.</p> <p>So, many people born earlier than the 1950s have experienced less perceptible warming in their local area than those born in the 1960s and 1970s. This may seem counter-intuitive. But a cooling trend in the first few decades of one’s life means the warming experienced over an entire lifespan (from birth until today) is smaller and less detectable.</p> <p>So what does all this mean? People in equatorial areas born in the 1960s and 1970s – now aged between about 45 and 65 – have experienced more perceptible warming than anyone else on Earth.</p> <h2>Rich countries must act</h2> <p>Our findings are important, for several reasons.</p> <p>Identifying who has experienced significant global warming in their lives may help explain <a href="https://www.nature.com/articles/nclimate2660">attitudes to tackling climate change</a>.</p> <p>Our findings also raise significant issues of fairness and equity.</p> <p>Humanity will continue to warm the planet until we reach global net-zero emissions. This means many young people in lower-income countries may, later in life, experience a local climate that is unrecognisable to that of their youth.</p> <p>Of course, warming temperatures are not the only way people experience climate change. Others include sea-level rise, more intense drought and rainfall extremes. We know many of these impacts are felt most acutely by <a href="https://www.aljazeera.com/opinions/2022/5/11/climate-change-is-devastating-the-global-south">the most vulnerable populations</a>.</p> <p>Cumulative greenhouse gas emissions are much higher in the Global North, due to economic development. To address this inequality, rich industrialised nations must take a leading role in reducing emissions to net-zero, and helping vulnerable countries adapt to climate change.<!-- Below is The Conversation's page counter tag.

Big hair? Bald? How much difference your hair really makes to keep you cool or warm

<p><a href="https://theconversation.com/profiles/theresa-larkin-952095">Th<em>eresa Larkin</em></a><em>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>We have <a href="https://theconversation.com/health-check-why-does-womens-hair-thin-out-39126">millions</a> of hair follicles on our body, including around 100,000 on our scalp.</p> <p>This might sound like a lot of hair, yet humans are described as “hairless”. We have evolved to be the only mammals with a relatively hairless body, but still with scalp hair.</p> <p>So how does your hair affect your body temperature when it’s hot or cold?</p> <p>Compared with other animals, our hair does not have as much influence on keeping us warm or cool as you might think.</p> <h2>Essential to our survival</h2> <p>Our brain function and body’s metabolism depend on an optimal temperature of around 37℃. Thermoregulation maintains this body temperature, even when we are exposed to a hotter or colder external temperature.</p> <p>For non-human mammals, body hair or fur plays a role in protecting against environmental cold or heat.</p> <p>For instance, a heavy fur coat helps keep a polar bear <a href="https://polarbearsinternational.org/polar-bears-changing-arctic/polar-bear-facts/adaptions-characteristics/">warm</a> in the cold. But fur also keeps an animal cool in the heat because it can <a href="https://www.jstor.org/stable/25064866">absorb or reflect</a> radiant heat.</p> <p>Scientists think this is why humans have kept hair on our heads. Our heads are exposed to the most heat from the sun, and scalp hair keeps our heads cool.</p> <p>Research published just last week <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">suggests</a> curly hair provides the best heat protection. That’s because curly hair’s thicker layer of insulation reduces the amount of sun that reaches the scalp.</p> <h2>But hair is not the only factor</h2> <p>When humans moved from living in the jungle to the savannah, they needed to walk and run long distances in the sun. This meant they needed a way to handle the increased body temperature that comes with physical activity in the heat.</p> <p>Sweating is the best way to lose heat and cool down, but the presence of hair reduces sweating and heat loss from the skin.</p> <p>So humans evolved to <a href="https://www.pnas.org/doi/10.1073/pnas.1113915108">lose body hair</a> to be better adapted to exercising in the heat. Fewer hair follicles in our skin made room for more sweat glands. This made our skin optimal for sweat evaporation – and the <a href="https://theconversation.com/want-to-keep-cool-on-hot-summer-days-heres-how-34489">heat loss</a> that goes with it – to keep us cool.</p> <h2>So what’s best in the heat?</h2> <p>You might think removing body hair or having a bald head is best for sweating and keeping cool when exercising in the heat. However, it’s not that simple.</p> <p>Removing head hair would increase the <a href="https://www.pnas.org/doi/10.1073/pnas.2301760120">amount of sun</a> that reaches your scalp. This means you would need to <a href="https://pubmed.ncbi.nlm.nih.gov/20683812/">sweat more</a> during exercise in the sun to reduce an increase in body temperature, but not by much.</p> <p>In fact, it’s the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">least hairy</a> areas of our body that have the highest sweat rates during exercise. These are our forehead, neck, feet and hands.</p> <p>So the best way to keep cool in the heat is to keep these areas uncovered (but still use sunscreen). Removing body hair will not have a large impact on your overall sweat rate.</p> <h2>How about when it’s cold?</h2> <p>Our body hair and head hair theoretically have a role in keeping us warm, but the effects are minimal.</p> <p>When we are cold, the muscles of the hair follicles on the body contract to cause the hairs to stand straight. This is an attempt to trap heat close to the body and we see this as goosebumps. However, because our body hair is so thin, this does not have a big effect in keeping us warm.</p> <p>Our head hair can prevent some heat loss from the head, but again this is limited.</p> <p>When it’s cold, heat can still be lost through the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4667044/#:%7E:text=The%20body%20hair%20is%20advantageous,heat%20removal%20during%20heat%20stress.">skin of the head</a> regardless of your hairstyle.</p> <p>The scalp also has only a very thin layer of fat compared to the rest of our skin, so our head has less insulation to protect against the cold.</p> <p>A warm hat or beanie is the only way to prevent too much heat lost from the head.</p> <h2>In a nutshell</h2> <p>Our head and body hair, or lack of it, does have a small role in how you maintain your body temperature.</p> <p>But overall, your hairstyle does not influence whether you feel warm or cool.<!-- Below is The Conversation's page counter tag.

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.

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.

Perhaps there are even benefits as the previous US secretary of state, Mike Pompeo, <a href="https://edition.cnn.com/2019/05/06/politics/pompeo-sea-ice-arctic-council/index.html">once declared</a> – it means ships from Asia can potentially save around 3,000 miles of journey to European ports in summer at least.</p> <p>But Arctic sea ice is an important component of the climate system. 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.

COVID is officially no longer a global health emergency – here’s what that means (and what we’ve learned along the way)

<p>World Health Organisation (WHO) experts <a href="https://www.nytimes.com/2023/05/05/health/covid-who-emergency-end.html">have officially declared</a> that COVID <a href="https://www.who.int/news/item/05-05-2023-statement-on-the-fifteenth-meeting-of-the-international-health-regulations-(2005)-emergency-committee-regarding-the-coronavirus-disease-(covid-19)-pandemic">no longer constitutes</a> a public health emergency of international concern (Pheic). This coincides with the WHO’s new <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">strategy</a> to transition from an emergency response to longer-term sustained COVID disease management. </p> <p>This may not change too much practically. COVID will still have pandemic status, and countries will continue to have their own authority as to whether to treat COVID as an emergency within their territories (some countries, <a href="https://www.npr.org/2023/04/11/1169191865/biden-ends-covid-national-emergency">including the US</a>, have already declared an end to the national emergency).</p> <p>For the global public health community, however, this is an event of monumental importance, drawing to a close the emergency response period which commenced on <a href="https://www.who.int/publications/m/item/covid-19-public-health-emergency-of-international-concern-(pheic)-global-research-and-innovation-forum">January 30 2020</a>. </p> <p>At the same time, for a large portion of the general public, it may well pass by relatively unnoticed. For many people, it’s been a long time since they viewed COVID as an emergency. In the UK for example, COVID no longer features in the regular Office for National Statistics <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/19aprilto1may2023">public opinion survey</a> that asks people what they think the key issues facing the country are. Even a year ago, <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/30marchto24april2022">only two in five Britons</a> were very or somewhat worried about COVID, according to the survey.</p> <p>Along with other behavioural scientists, I have been following <a href="https://www.swansea.ac.uk/research/research-highlights/health-innovation/public-during-pandemic/">public experiences of the pandemic</a> for the past three years. The results have yet to be peer reviewed but by summer 2022, many participants in <a href="https://psyarxiv.com/d6jcv">our research</a> described the pandemic as being like “a distant memory” or like it “never happened”.</p> <p>As we move into this next phase, it’s time to consider what we’ve learned about human behaviour during the pandemic, and what happens next.</p> <h2>Old habits die hard</h2> <p>In the early days of the pandemic, many behavioural scientists, myself included, wondered whether some of our pandemic habits <a href="https://theconversation.com/two-years-into-the-pandemic-which-of-our-newly-formed-habits-are-here-to-stay-178204">were here to stay</a>. Would <a href="https://www.itv.com/news/wales/2021-04-02/masks-to-stay-soldiering-on-through-the-common-cold-will-stop-and-the-nature-of-work-has-changed-forever-expert-says">face masks</a> become a regular wardrobe staple? Would people stop “soldiering on” and going into work when unwell?</p> <p>It turned out that for most people, the pandemic hasn’t permanently changed our behaviour and habits or created a “<a href="https://psyarxiv.com/d6jcv">new normal</a>”. Looking again at the UK, face mask use has consistently declined, with <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/datasets/publicopinionsandsocialtrendsgreatbritaincoronaviruscovid19andotherillnesses">figures from last month</a> suggesting that fewer than one in six adults had worn a face mask recently. Regular use is likely much less common. </p> <p>Social distancing has long since disappeared, except for a relatively small proportion of the public, in particular those most vulnerable to COVID.</p> <p>The COVID pandemic has taught us how adaptive behaviour can be, in particular how much people were willing to change their behaviour to keep themselves and others safe. Most people <a href="https://academic.oup.com/abm/article/56/8/781/6618645?login=false">followed the rules</a> during <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0258781">the height of the pandemic</a>, no matter how difficult. COVID has reminded us <a href="https://www.cambridge.org/core/services/aop-cambridge-core/content/view/759BE02FFE73E5C05EA429A3E1547D78/S2056467821000050a.pdf/resilience_in_the_age_of_covid19.pdf">how resilient we humans can be</a>.</p> <p>These pandemic adaptions, and the fact that our pre-pandemic behaviour bounced back so quickly, shows how important social cues and social norms are to behaviour. Putting on a mask or keeping our distance from others were habits – <a href="https://www.sciencedirect.com/science/article/abs/pii/S002210311100254X">actions triggered automatically</a> in response to contextual cues, such as seeing signs with pictures of people socially distancing.</p> <p>Social norms – what we think others are doing – were key to <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0277360">vaccine uptake</a> and to our uptake of <a href="https://www.nature.com/articles/s41562-020-0884-z">preventative measures in general</a>. As these contextual cues disappeared and the social norms started to change, and as vaccine coverage increased and the risk to the majority decreased, our behaviour changed.</p> <p>The pandemic has also demonstrated how important social connections and social, especially physical, contact can be. This is something <a href="https://theconversation.com/handshakes-and-hugs-are-good-for-you-its-vital-they-make-a-comeback-after-the-pandemic-158174">we have already argued</a> COVID couldn’t keep at bay forever. According to social safety theory, which sees stress and wellbeing as a product of biological, psychological and social factors, COVID <a href="https://www.sciencedirect.com/science/article/pii/S2352250X2200001X">posed a threat</a> to the “social fabric that makes humans resilient and keeps us alive and well”. </p> <p>It’s unsurprising that life satisfaction and happiness were <a href="https://bmjopen.bmj.com/content/10/7/e039334">lowest during lockdowns</a>, and <a href="https://www.covidsocialstudy.org/_files/ugd/064c8b_c525505ffa6b432f96dc41d6b6a985ea.pdf">recovered as people started to mix socially again</a>.</p> <h2>The emergency isn’t over for everyone</h2> <p>As we mark the end of the emergency phase it’s important to remember the <a href="https://covid19.who.int/">nearly seven million lives lost</a> due to COVID since 2020.</p> <p>And of course, we must consider that for some, especially those who are clinically vulnerable, the emergency is not yet over, and may never be.</p> <p>Although it’s no longer a Pheic, <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">as the WHO reminds us</a>, COVID is still responsible for millions of infections and thousands of deaths each week around the world. Also, thanks to long COVID, hundreds of millions of people are in need of longer-term care.</p> <p>In the future, we need to move from relying on the resilience of individuals to building resilience in our institutions. We can all take measures to continue to protect ourselves and those around us from COVID and other respiratory viruses (such as by <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00021-1/fulltext">hand washing</a> and keeping up to date with vaccinations). But responsibility for preventing public health emergencies shouldn’t rest <a href="https://blogs.bmj.com/bmj/2020/03/17/uks-coronavirus-policy-places-too-much-responsibility-in-the-hands-of-the-public/">solely in the hands of the public</a></p> <p>Actions that governments, employers and health authorities can take now could <a href="https://www.theguardian.com/books/2022/may/11/preventable-by-devi-sridhar-review-a-resolutely-global-view-of-covid">protect against</a> future <a href="https://pubmed.ncbi.nlm.nih.gov/34872923/">public health emergencies</a>.

9 cost-effective ways to warm your home this winter

<p>Sick of hearing about the same old heating methods that never quite do the job? Try these nine unconventional heating hacks. </p> <p><strong>1. Preheat your pyjamas </strong></p> <p>While you shower, put your pyjamas in the dryer to ensure that you have toasty warm clothing to change into as soon as you leave the warmth of the bathroom. For a slightly more affordable version, wrap your PJs in a hot water bottle or heat bag, not only will it heat your clothes but it will make your bed toasty warm too, just be sure to remove the hot water bottle from your bed before you settle down to sleep for the night. </p> <p><strong>2. Join the fan club</strong></p> <p>It might seem counter-productive but turning a fan on at the lowest setting will help circulate heat throughout the room. Don't knock it until you try it!</p> <p><strong>3. Hottie in the car </strong></p> <p>Dreading your chilly morning commute to work? Make your early start a little easier to stomach by putting hand warmers into your pockets or heat up a hot water bottle with warm water or a heat bag and put it on your lap as you drive. </p> <p><strong>4. Utilise bubble wrap</strong></p> <p>For those whose home insulation isn't up to scratch, a budget-friendly trick is to use bubble wrap to insulate your windows from the inside. To create the DIY double glazing, simply get some bubble wrap and use a product like blue-tac to hold it in place on your windows.</p> <p><strong>5. Make use of your curtains</strong></p> <p>Keep your house warmer for longer by making use of your curtains and the limited winter sun. To do this, open all of your curtains on a sunny morning and allow the house to soak up as much heat as possible during the day. As night falls, let your curtains act as an additional piece of insulation by closing them at dusk and trapping heat inside the house.</p> <p><strong>6. Cuddle your pet</strong></p> <p>When in doubt, a great way to stay warm on a cold night is by sharing body heat. While snuggling up with your partner might make you a little bit warmer, cuddling a furry pet will heat you up a lot faster. The key to success with this hack is to cuddle up with the fluffiest animal possible, so try and find a friend with a Ragdoll cat or a St Bernard.</p> <p>7. Go camping… indoors</p> <p><strong>Just because it's winter does</strong>n't mean you can't go camping... well, as long as it's in the living room. For a warm night's sleep, fill up a tent with pillows and blankets, make sure it's all zipped up and settle down for the night. The enclosed space will heat up by trapping the air and using your body warmth to make the space nice and cosy.</p> <p><strong>8. Redecorate</strong></p> <p>Positioning your favourite seat in front of the heater might feel great when you're sitting in it, but when you put furniture too close to a heating source you're actually stopping the hot air from circulating throughout the rest of the room. Fix this problem by repositioning your furniture and allowing the hot air to fill the whole room, rather than just absorbing it all up in one spot.</p> <p><strong>9. Get in the kitchen</strong></p> <p>There's nothing like a good soup or a roast to make you feel better on a cold winter’s night. Cooking is an easy way to warm up the air in your home, while also providing you with something warm to eat at the same time. </p> <p><em>Republished with permission of <a href="http://www.stuff.co.nz/" target="_blank" rel="noopener"><strong><span style="text-decoration: underline;">Stuff.co.nz</span></strong></a>.</em></p> <p><em>Images: Getty</em></p>

As the global musical phenomenon turns 50, a hip-hop professor explains what the word ‘dope’ means to him

<p>After I finished my Ph.D. in 2017, several newspaper reporters wrote about the job I’d accepted at the University of Virginia as an assistant professor of hip-hop.</p> <p>“A.D. Carson just scored, arguably, the dopest job ever,” one <a href="https://www.usatoday.com/story/news/2017/07/03/virginia-ad-carson-hip-hop-professor/435032001/">journalist wrote</a>.</p> <p>The writer may not have meant it the way I read it, but the terminology was significant to me. Hip-hop’s early luminaries transformed the word’s original meanings, using it as a synonym for cool. In the 50 years since, it endures as an expression of respect and praise – and illegal substances.</p> <p>In that context, dope has everything to do with my work. </p> <p>In the year I graduated from college, one of my best friends was sent to federal prison for possession of crack cocaine with intent to distribute. He served nearly a decade and has been back in prison several times since.</p> <p>But before he went to prison, he helped me finish school by paying off my tuition.</p> <p>In a very real way, dope has as much to do with me finishing my studies and becoming a professor as it does with him serving time in a federal prison.</p> <h2>Academic dope</h2> <p>For my Ph.D. dissertation in Rhetorics, Communications, and Information Design, I wrote a <a href="http://phd.aydeethegreat.com/">rap album</a> titled “Owning My Masters: The Rhetorics of Rhymes &amp; Revolutions.” A peer-reviewed, mastered version of the album is due out this summer from University of Michigan Press.</p> <p>Part of my reasoning for writing it that way involved my ideas about dope. I want to question who gets to determine who and what are dope and whether any university can produce expertise on the people who created hip-hop.</p> <p>While I was initially met with <a href="https://www.theatlantic.com/national/archive/2016/04/clemson-university-arrests/478455/">considerable resistance</a> for my work at Clemson, the university eventually became supportive and touted “<a href="https://news.clemson.edu/clemson-doctoral-student-produces-rap-album-for-dissertation-it-goes-viral/">a dissertation with a beat</a>.”</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">A Dissertation with a Beat. 🔊🎤 🔊<a href="https://twitter.com/hashtag/Clemson?src=hash&amp;ref_src=twsrc%5Etfw">#Clemson</a> doctoral student produces rap album for dissertation; it goes viral ➡️ <a href="https://t.co/wgiM9LS6k5">https://t.co/wgiM9LS6k5</a> <a href="https://t.co/r1lmBYXV2S">pic.twitter.com/r1lmBYXV2S</a></p> <p>— Clemson University (@ClemsonUniv) <a href="https://twitter.com/ClemsonUniv/status/845990987440652289?ref_src=twsrc%5Etfw">March 26, 2017</a></p></blockquote> <p>Clemson is not the only school to recognize hip-hop as dope. </p> <p>In the 50 years since its start at <a href="https://theconversation.com/hip-hop-holiday-signals-a-turning-point-in-education-for-a-music-form-that-began-at-a-back-to-school-party-in-the-bronx-165525">a back-to-school party</a> in the South Bronx, hip-hop, the culture and its art forms have come a long way to a place of relative prominence in educational institutions. </p> <p>Since 2013, Harvard University has housed the <a href="https://hutchinscenter.fas.harvard.edu/institutes/hiphop-archive-research-institute">Hiphop Archive &amp; Research Institute</a> and the <a href="https://hutchinscenter.fas.harvard.edu/faq/nasir-jones-hiphop-fellowship">Nasir Jones Hiphop Fellowship</a> that funds scholars and artists who demonstrate “exceptional scholarship and creativity in the arts in connection with Hiphop.”</p> <p>UCLA announced an <a href="https://www.latimes.com/entertainment-arts/music/story/2022-03-28/ucla-hip-hop-initiative-chuck-d">ambitious Hip Hop Initiative</a> to kick off the golden anniversary. The initiative includes artist residencies, community engagement programs, a book series and a digital archive project.</p> <p>Perhaps my receiving tenure and promotion at the University of Virginia is part of the school’s attempt to help codify the existence of hip-hop scholarship.</p> <p>When I write about “dope,” I’m thinking of Black people like drugs to which the U.S. is addicted. </p> <p>Dope is a frame to help clarify the attempts, throughout American history, at outlawing and <a href="https://www.ilsos.gov/departments/archives/online_exhibits/100_documents/1853-black-law.html">legalizing</a> the presence of Black people and Black culture. As dope, Black people are America’s constant ailment and cure.</p> <p>To me, dope is an aspiration and a methodology to acknowledge and resist America’s steady surveillance, scrutiny and criminalization of Blackness.</p> <p>By this definition, dope is not only what we are, it’s also who we want to be and how we demonstrate our being. </p> <p>Dope is about what we can make with what we are given. </p> <p>Dope is a product of conditions created by America. It is also a product that helped create America.</p> <p>Whenever Blackness has been seen as lucrative, businesses like record companies and institutions like colleges and universities have sought to capitalize. To remove the negative stigmas associated with dope, these institutions cast themselves in roles similar to a pharmacy. </p> <p>Even though I don’t believe academia has the power or authority to bestow hip-hop credibility, a question remains – does having a Ph.D and producing rap music as <a href="https://theconversation.com/hip-hop-professor-looks-to-open-doors-with-worlds-first-peer-reviewed-rap-album-153761">peer-reviewed publications</a>change my dopeness in some way?</p> <h2>Legalizing dope</h2> <p>Though I earned a Ph.D by rapping, my own relationship to hip-hop in academic institutions remains fraught. </p> <p>Part of the problem was noted in 2014 by Michelle Alexander, a legal scholar and author of “<a href="http://newjimcrow.com/">The New Jim Crow</a>,” when she talked about <a href="http://www.drugpolicy.org/resource/new-jim-crow-whats-next-talk-michelle-alexander-and-dpas-asha-bandele">her concerns about</a> the legalization of marijuana in different U.S. states.</p> <p>“In many ways the imagery doesn’t sit right,” she said. “Here are white men poised to run big marijuana businesses … after 40 years of impoverished black kids getting prison time for selling weed, and their families and futures destroyed. Now, white men are planning to get rich doing precisely the same thing?”</p> <p>I feel the same way about dopeness in academia. Since hip-hop has emerged as a global phenomenon largely embraced by many of the “academically trained” music scholars who initially rejected it, how will those scholars and their schools now make way for the people they have historically excluded?</p> <p>This is why that quote about me “scoring, arguably, the dopest job ever” has stuck with me. </p> <p>I wonder if it’s fair to call what I do a form of legalized dope.</p> <h2>America’s dope-dealing history</h2> <p>In the late 1990s, I saw how fast hip-hop had become inescapable across the U.S., even in the small Midwestern town of Decatur, Illinois, where I grew up with my friend who is now serving federal prison time. </p> <p>He and I have remained in contact. Among the things we discuss is how unlikely it is that I would be able to do what I do without his doing what he did.</p> <p>Given the economic realities faced by people after leaving prison, we both know there are limitations to his opportunities if we choose to see our successes as shared accomplishments.</p> <p>Depending on how dope is interpreted, prisons and universities serve as probable destinations for people who make their living with it. It has kept him in prison roughly the same amount of time as it has kept me in graduate school and in my profession. </p> <p>This present reality has historical significance for how I think of dope, and what it means for people to have their existence authorized or legalized, and America’s relationship to Black people. </p> <p>Many of the buildings at Clemson were built in the late 1880s using “<a href="http://glimpse.clemson.edu/convict-labor/">laborers convicted of mostly petty crimes</a>” that the state of South Carolina leased to the university. </p> <p>Similarly, the University of Virginia was built by <a href="https://dei.virginia.edu/resources">renting enslaved laborers</a>. The University also is required by state law to purchase office furniture from a state-owned company that <a href="https://www.insidehighered.com/news/2020/02/14/public-universities-several-states-are-required-buy-prison-industries">depends on imprisoned people for labor</a>. The people who make the furniture are paid very little to do so. </p> <p>The people in the federal prison where my friend who helped me pay for college is now housed work for paltry wages making towels and shirts for the U.S. Army.</p> <p>Even with all of the time and distance between our pasts and present, our paths are still inextricably intertwined – along with all those others on or near the seemingly transient line that divides “legal” and “illegal” dope.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/as-the-global-musical-phenomenon-turns-50-a-hip-hop-professor-explains-what-the-word-dope-means-to-him-200872" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Global review shows link between social media use, body image and eating disorders

<p>Body image has remains a <a href="https://www.missionaustralia.com.au/what-we-do/research-impact-policy-advocacy/youth-survey" target="_blank" rel="noopener">top personal concern</a> for young people in Australia, with 76% concerned about the issue. </p> <p>Social media use by teens is rising at the same time – with <a href="https://www.aacap.org/AACAP/Families_and_Youth/Facts_for_Families/FFF-Guide/Social-Media-and-Teens-100.aspx" target="_blank" rel="noopener">more than 90% on platforms</a> like Facebook, YouTube, Instagram, Snapchat, WeChat and TikTok.</p> <p>While there have long been concerns about the association between social media, body image and eating disorders the connection remains relatively unexplored as a public health issue.</p> <p>Now, researchers from University College London in the UK have undertaken a systematic review of 50 scientific studies across 17 countries showing  clear links between social media use and body image concerns.</p> <p>The paper, <a href="https://doi.org/10.1371/journal.pgph.0001091" target="_blank" rel="noopener">published</a> in PLOS Global Public Health, analyses the relationship between body image or eating disorders in young people and social media use. </p> <p>The researchers identify specific aspects of social media – platforms with an emphasis on photos, and engaging with “fitspiration” and “thinspiration” trends – as the factors most closely linked to body image concerns, disordered eating and poor mental health.</p> <p>Other key risk factors included female gender, high body-mass-index and pre-existing body image concerns. </p> <p>The researchers note further studies are needed into the direction of causality. </p> <p>“For example, do body image dissatisfaction and disordered eating occur because of social media usage, or do these pre-exist, encourage engagement in certain online activities, and result in unfavourable clinically significant outcomes?” they ask.</p> <p>Eating disorders involve disturbed attitudes to body image, pre-occupation with weight and body shape and are associated with significant negative outcomes such as cardiovascular disease, reduced bone density, and psychiatric conditions.</p> <p>In Australia, the <a href="https://butterfly.org.au/" target="_blank" rel="noopener">Butterfly Foundation</a> reports eating disorders affect around one million people, with the conditions causing more people die each year than the road toll. </p> <p><em>Image credits: Getty Images  </em></p> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/health/social-media-use-body-image/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Petra Stock. </em></p>

The wellbeing ‘pandemic’ – how the global drive for wellness might be making us sick

<p>Are we in the midst of a wellbeing pandemic? The question may seem curious, even contradictory. But look around, the concept is everywhere and spreading: in the media, in government institutions and transnational organisations, in schools, in workplaces and in the marketplace. </p> <p>To be clear, it’s not just wellbeing’s infectiousness in public discourse that makes it pandemic-like. It’s also the genuine malaise that can be caused by the term’s misuse and exploitation.</p> <p>Do you sense, for example, that your wellbeing is increasingly being scrutinised by peers, managers and insurance companies? Are you noticing an increasing number of advertisements offering products and services that promise enhanced wellbeing through consumption? If so, you’re not alone. </p> <p>But we also need to ask whether this obsession with wellbeing is having the opposite to the desired effect. To understand why, it’s important to look at the origins, politics and complexities of wellbeing, including its strategic deployment in the process of what we call “<a href="https://otagouni-my.sharepoint.com/personal/jacst99p_registry_otago_ac_nz/Documents/Documents/SJ-Wellness/SJ-Conversation-Wellbeing/Jackson-Sam-Dawson-Porter-Frontiers-Sociology-Wellbeing-2022.pdf">wellbeing washing</a>”.</p> <h2>The halo effect</h2> <p>While concerns about wellbeing can be traced to antiquity, the term has emerged as a central feature of contemporary social life. One explanation is that it is often conflated with concepts as diverse as happiness, quality of life, life satisfaction, human flourishing, mindfulness and “wellness”. </p> <p>Wellbeing is flexible, in the sense that it can be easily inserted into a diverse range of contexts. But it’s also surrounded by a kind of halo, automatically bestowed with a positive meaning, similar to concepts such as motherhood, democracy, freedom and liberty. </p> <p>To contest the value and importance of such things is to risk being labelled a troublemaker, a non-believer, unpatriotic or worse.</p> <p>These days, there are two main concepts of wellbeing. The first – subjective wellbeing – emphasises a <a href="https://www.frontiersin.org/articles/10.3389/fsoc.2022.950557/full#B21">holistic measure</a> of an individual’s mental, physical and spiritual health. This perspective is perhaps best reflected in the World Health Organization’s <a href="https://www.corc.uk.net/outcome-experience-measures/the-world-health-organisation-five-well-being-index-who-5/">WHO-5 Index</a>, designed in 1998 to measure people’s subjective wellbeing according to five states: cheerfulness, calmness, vigour, restfulness and fulfilment.</p> <p>Translated into more than 30 languages, the overall influence of the WHO-5 Index should not be underestimated; both governments and corporations have embraced it and implemented policy based on it. </p> <p>But the validity of the index, and others like it, has been questioned. They’re prone to oversimplification and a tendency to marginalise alternative perspectives, including Indigenous approaches to physical and mental health.</p> <h2>Individual responsibility</h2> <p>The second perspective – objective wellbeing – was a response to rising social inequality. It focuses on offering an <a href="https://www.frontiersin.org/articles/10.3389/fsoc.2022.950557/full#B60">alternative to GDP</a> as a measure of overall national prosperity. </p> <p>One example of this is New Zealand’s <a href="https://www.treasury.govt.nz/information-and-services/nz-economy/higher-living-standards/our-living-standards-framework">Living Standards Framework</a>, which is guided by four operating principles: distribution, resilience, productivity and sustainability. These new and purportedly more progressive measures of national economic and social outcomes signal societal change, optimism and hope.</p> <p>The trouble with such initiatives, however, is that they remain rooted within a particular neoliberal paradigm in which individual behaviour is the linchpin for change, rather than the wider political and economic structures around us.</p> <p>Arguably, this translates into more monitoring and “disciplining” of personal actions and activities. Intentionally or not, many organisations interpret and use wellbeing principles and policies to reinforce existing structures and hierarchies. </p> <p>Consider how the wellbeing agenda is playing out in your organisation or workplace, for example. Chances are you have seen the growth of new departments, work units or committees, policies and programs, wellness workshops – all supposedly linked to health and wellbeing. </p> <p>You may even have noticed the creation of new roles: wellbeing coaches, teams or “champions”. If not, then “lurk with intent” and be on the lookout for the emergence of yoga and meditation offerings, nature walks and a range of other “funtivities” to support your wellbeing. </p> <h2>Wellbeing washing</h2> <p>The danger is that such initiatives now constitute another semi-obligatory work task, to the extent that non-participation could lead to stigmatisation. This only adds to stress and, indeed, unwellness. </p> <p>Deployed poorly or cynically, such schemes represent aspects of “wellbeing washing”. It’s a strategic attempt to use language, imagery, policies and practices as part of an organisation’s “culture” to connote something positive and virtuous. </p> <p>In reality, it could also be designed to enhance productivity and reduce costs, minimise and manage reputational risk, and promote <a href="https://otagouni-my.sharepoint.com/personal/jacst99p_registry_otago_ac_nz/Documents/Documents/SJ-Wellness/SJ-Conversation-Wellbeing/Jackson-Sam-Dawson-Porter-Frontiers-Sociology-Wellbeing-2022.pdf">conformity, control and surveillance</a>. </p> <p>Ultimately, we argue that wellbeing now constitutes a “field of power”; not a neutral territory, but a place where parties advance their own interests, often at the expense of others. As such, it’s essential that scholars, policymakers and citizens explore, as one author <a href="https://www.google.com.au/books/edition/Measuring_Wellbeing/lWBXjk1nocIC?hl=en&amp;gbpv=1&amp;dq=%E2%80%9Cwhat+and+whose+values+are+represented,+which+accounts+dominate,+what+is+their+impact+and+on+whom%E2%80%9D&amp;pg=PA4&amp;printsec=frontcover">put it</a>, “what and whose values are represented, which accounts dominate, what is their impact and on whom”. </p> <p>Because if wellbeing is becoming a pandemic, we may well need the “vaccine” of critical reflection.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/the-wellbeing-pandemic-how-the-global-drive-for-wellness-might-be-making-us-sick-198662" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Air travel spreads infections globally, but health advice from inflight magazines can limit that

<p>“Travel safe, travel far, travel wide, and travel often,” <a href="https://thoughtcatalog.com/matthew-kepnes/2014/01/53-travel-quotes-to-inspire-you-to-see-the-world/">says</a> <a href="https://www.nomadicmatt.com/">Nomadic Matt</a>, the American who quit his job to travel the world, write about it and coach others to do the same.</p> <p>But there’s a downside to all this travel, with its unprecedented volume of passengers moving from one side of the world to the other, largely by plane.</p> <p>There’s the risk of those passengers spreading infectious diseases and microorganisms resistant to multiple drugs (superbugs) around the world.</p> <p>Yet, our recently published <a href="https://www.sciencedirect.com/science/article/pii/S1477893919301218">research</a> into health advice provided by inflight magazines shows plane passengers are given practically no advice on how to limit the spread of infectious diseases.</p> <p>Should we be worried about the part air travel plays in spreading infectious diseases? And what can we do about it?</p> <p><strong>How big is the risk?</strong></p> <p>Low airfares and a series of social and economic factors have made global air travel more common than ever. According to the Australian government department of infrastructure, transport, cities and regional development the <a href="https://www.bitre.gov.au/publications/ongoing/files/International_airline_activity_CY2018.pdf">number of passengers taking international scheduled flights in 2018 was 41.575 million</a>. But the International Air Transport Association projects passenger demand will <a href="https://www.iata.org/pressroom/pr/Pages/2019-02-27-02.aspx">reach 8.2 billion by 2037</a>.</p> <p>There are many examples of infectious diseases spread via international flying. The World Health Organization documented <a href="https://www.who.int/ith/mode_of_travel/tcd_aircraft/en/">transmission of tuberculosis</a> (TB) on board commercial aircraft during long-haul flights during the 1980s.</p> <p>Research published in 2011 documents the <a href="https://wwwnc.cdc.gov/eid/article/17/7/10-1135_article">transmission of influenza</a> on two transcontinental international flights in May 2009.</p> <p>More recently, the current <a href="https://theconversation.com/why-people-born-between-1966-and-1994-are-at-greater-risk-of-measles-and-what-to-do-about-it-110167">global outbreak of measles</a> in many countries, including the Philippines and the United States, gave rise to the risk of transmission during international travel. In a recent case a <a href="https://www.health.nsw.gov.au/Infectious/alerts/Pages/measles-alert-january.aspx">baby</a> too young to be vaccinated who had <a href="https://www.smh.com.au/national/nsw/measles-alert-after-infectious-baby-flew-from-manila-went-to-central-coast-20190603-p51tzs.html">measles</a> returned from Manilla in the Philippines to Sydney, exposing travellers on that flight to infection.</p> <p>Then there is the risk of transmitting antimicrobial-resistant organisms that cause disease, such as <a href="https://theconversation.com/explainer-what-is-tb-and-am-i-at-risk-of-getting-it-in-australia-75290">multi-drug resistant TB</a>.</p> <p>Recently, patients in Victoria and New South Wales were identified as carrying the drug-resistant fungus <a href="https://www2.health.vic.gov.au/about/news-and-events/healthalerts/candida-auris-case-detected-in-victoria"><em>Candida auris</em></a>, which they acquired overseas.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pubmed/27890665">One study</a> estimates that over 300 million travellers visit high-risk areas, such as the western Pacific, Southeast Asia and Eastern Mediterranean, each year worldwide, and more than 20% return as new carriers of resistant organisms.</p> <p>These popular destinations, as well as the Middle East, have high rates of drug resistant organisms.</p> <p><strong>How is this happening?</strong></p> <p>Aircraft move large volumes of people around the world swiftly. But what sets them apart from buses and trains is that passengers are close together, in confined spaces, for a long time. This increases the risk of transmitting infections.</p> <p>Passengers interact with high-touch surfaces, such as tray tables, headsets, seats and handles. We cough, sneeze and touch multiple surfaces multiple times during a flight, with limited opportunities to clean our hands with soap and water.</p> <p>Many infections, such as gastroenteritis and diarrhoea, are spread and contracted by touch and contact.</p> <p><strong>What can we do about it?</strong></p> <p>Providing plane travellers with relevant health advice is one way to limit the spread of infectious diseases via air travel.</p> <p>This would include information and advice on routine hand washing with soap and water, or using alcohol-based hand rubs, and other basic measures including cough etiquette, such as coughing into your elbow and covering your nose and face.</p> <p><a href="https://academic.oup.com/jtm/article/4/2/102/1847252">Researchers</a> have looked at the role commercial websites and travel agencies might play in providing that advice. And since the 1990s, airline magazines have been <a href="https://academic.oup.com/jtm/article/4/2/102/1847252">highlighted</a> as an underused source of traveller health advice. More than 20 years on, we discovered little has changed.</p> <p>In our recent study, published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S1477893919301218">Travel Medicine and Infectious Disease</a>, we looked at the content of inflight magazines from 103 airlines issued during January 2019.</p> <p>Of the 47 available online, only a quarter (11) included an official section on passengers’ general health and well-being, of which only two contained information related to infection control and the preventing infectious diseases.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.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/284424/original/file-20190717-173366-w48bmn.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/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/284424/original/file-20190717-173366-w48bmn.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Inflight magazines have a potential audience of billions.

It advised passengers “with blood diseases or ear, nose and sinus infections should seek medical advice before flying”.</p> <p>There was no further explanation or information, nor were there any strategies to prevent these or other infections.</p> <p>The second magazine, from a USA-based airline, contained general travel health advice, but none specifically about infectious diseases.</p> <p>However there was a full-page, colour advertisement next to the health section. This contained images of many disease causing microorganisms on passengers’ tray tables and advocated the use of a disinfectant wipe for hands and other inflight surfaces.</p> <p>The slogan “because germs are frequent fliers” was displayed across the tray table. This was accompanied by information about the use and effectiveness of disinfectant wipes for hand hygiene and disinfecting surfaces during air travel, public transport use, and in hotels and restaurants.</p> <p>Inflight magazines are valuable assets for airlines and are the source of considerable advertising revenue. They are read by potentially billions of passengers every year. The results of this study show that they are a greatly underused source of information about infection control and measures to prevent the spread of infectious diseases.</p> <p>Airlines should also provide health advice to passengers in other media, in particular video screens, about infection prevention and basic control measures such as hand hygiene, cough etiquette and personal hygiene.</p> <p>Such advice should be provided before, during and after the flight. It could also include destination-related advice for particularly risky travel routes and destinations.</p> <p><strong>More information for passengers</strong></p> <p>Airlines providing health advice to passengers is just one way to limit the spread of infectious diseases and antimicrobial-resistant organisms around the world via air travel.</p> <p>This would need to sit alongside other measures, such as <a href="https://wwwnc.cdc.gov/travel/page/travel-industry-information-center">information and guidelines</a> provided to those who travel via the sea.</p> <p>The simple, low-cost measures highlighted in our research could go a long way to help passengers stay healthy and avoid illness from infectious diseases.

Europe warming at double the rate of other continents

<p>Europe is the fastest-warming continent in the world, according to a newly released report from the World Meteorological Organization.</p> <p>The State of the Climate in Europe report cites the loss of more than 25 metres of ice loss in alpine glaciers, and 20 metres of loss in Greenland (a Danish territory), as particularly responsible for the rise in ocean levels.</p> <p>Climate change events were also responsible for more than US$50 billion in damages.</p> <p>In its statement releasing the report, the WMO described Europe as the “live picture” of a world burdened by warming climate. Since 1990, Europe’s temperatures have undergone an average rate of temperature increase of 0.5 degrees each decade.</p> <p>That rate is twice as high as the next fastest warming continent.</p> <p>The WMO points to high-impact weather and climate events – nearly 85% of which were floods and storms – as directly affecting around 510,000 people.</p> <p>Extreme heat also took its toll, with provisional record temperatures experienced in southern Italy in August reaching 48.8°C. These temperatures influenced drought and low rainfall across the Mediterranean, leading to deadly wildfires that burned through three times the amount of land area than the region’s 15-year average up to 2020.</p> <h2>But are carbon emissions decreasing in Europe?</h2> <p>Fuel prices and the COVID-19 pandemic were major influences on the continent’s carbon emissions reduction, the WMO found.</p> <p>A 31% decline in carbon emissions between 1990 and 2020 was recorded, although it’s expected to be far less in 2021 due to the relaxation of COVID-19 restrictions and altered fuel prices.</p> <p>2021 also marked the introduction of EU legislation to make net zero by 2050 a legally-binding target for member nations.</p> <p>Although temperature data provided by six datasets showed a decrease in 2021 from the preceding year, it still marked one of the 10 warmest years on record.</p> <p>And observers will keenly await the release of next year’s 2022 appraisal, after record summer droughts and heatwaves heaped pressure on European nations.</p> <p>Even now, regions across the continent are recording their hottest temperatures for November on record. </p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">(2) More November records in Europe.<br />France had 21 records today (left column), the most important were: Aigues Mortes (POR since 1872), Aix en Provence and Valence (1st class stations).<br />In Austria 4 records beaten the highest was 23.3C at Hohe Wand (right column).<br />tb continued.. <a href="https://t.co/DjmR7oR0oR">pic.twitter.com/DjmR7oR0oR</a></p> <p>— Extreme Temperatures Around The World (@extremetemps) <a href="https://twitter.com/extremetemps/status/1587481854680219653?ref_src=twsrc%5Etfw">November 1, 2022</a></p></blockquote> <p>“[Europe] reminds us that even well-prepared societies are not safe from impacts of extreme weather events,” says WMO secretary-general Professor Petteri Taalas.</p> <p>“This year, like 2021, large parts of Europe have been affected by extensive heatwaves and drought, fuelling wildfires. In 2021, exceptional floods caused death and devastation.</p> <p>“On the mitigation side, the good pace in reducing greenhouse gases emissions in the region should continue and ambition should be further increased. Europe can play a key role towards achieving a carbon neutral society by the middle of the century to meet the Paris Agreement.”</p> <h2>Future outlook</h2> <p>The release of the report comes ahead of the global climate change conference to be held in Egypt, where delegations from around the world convene to recalibrate efforts to address climate change.</p> <p>Last year’s COP26 conference in Glasgow was criticised for scrubbing language to phase out coal from the final agreement. In its place came language to ‘phase down’ its use. Coal is the leading source of carbon emissions from energy use.</p> <p>Similarly, several nations failed to renew important targets to reduce carbon emissions by the end of the decade, considered an important tipping point if net zero by 2050 is to be achieved.</p> <p>The WMO echoed the most recent Intergovernmental Panel on Climate Change forecasts that weather, climate and water disasters will increase in the future, and that Europe will experience temperature rises at rates exceeding global average increases.</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/earth/europe-warming-at-double-the-rate-of-other-continents/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Matthew Agius.</strong></p> <p><em>Image: Getty</em></p>
