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.

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.

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>

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>

5 places in the world that have the best weather

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

Warming oceans may force New Zealand’s sperm and blue whales to shift to cooler southern waters

<p>The world’s oceans are absorbing more than <a href="https://www.un.org/en/climatechange/science/climate-issues/ocean-impacts" target="_blank" rel="noopener">90% of the excess heat and energy</a> generated by rising greenhouse gas emissions.</p> <p>But, as the oceans keep warming, rising sea temperatures generate unprecedented cascading effects that include the melting of polar ice, rising seas, marine heatwaves and ocean acidification.</p> <p>This in turn has profound impacts on marine biodiversity and the lives and livelihoods of coastal communities, especially in island nations such as New Zealand.</p> <p>In our latest <a href="https://www.sciencedirect.com/science/article/pii/S1470160X22007075?via%3Dihub" target="_blank" rel="noopener">research</a>, we focused on great whales – sperm and blue whales in particular. They are crucial for maintaining healthy marine ecosystems, but have limited options to respond to climate change: either adapt, die, or move to stay within optimal habitats.</p> <p>We used mathematical models to predict how they are likely to respond to warming seas by the end of the century. Our results show a clear southward shift for both species, mostly driven by rising temperatures at the sea surface.</p> <h2>Computing the fate of whales</h2> <p>Data on the local abundance of both whales species are <a href="https://www.int-res.com/abstracts/meps/v690/p201-217/" target="_blank" rel="noopener">deficient</a>, but modelling provides a powerful tool to predict how their range is likely to shift.</p> <p>We used a <a href="http://macroecointern.dk/pdf-reprints/AraujoNew2007.pdf" target="_blank" rel="noopener">combination of mathematical models</a> (known as correlative species distribution models) to predict the future range shifts of these whale species as a response to three future climate change scenarios of differing severity, as outlined by the Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch/" target="_blank" rel="noopener">IPCC</a>).</p> <p>We applied these models, using the whales’ present distributions, to build a set of environmental “rules” that dictate where each species can live. Using climate-dependent data such as sea-surface temperature and chlorophyll A (a measure of phytoplankton growth), as well as static data such as water depth and distance to shore, we applied these rules to forecast future habitat suitability.</p> <p>We chose a scenario of “<a href="https://www.nature.com/articles/d41586-020-00177-3" target="_blank" rel="noopener">modest</a>” response to cutting greenhouse gas emissions (the IPCC’s mitigation strategy RCP4.5), which is the most likely given the current policies, and a worst-case scenario (no policy to cut emissions, RCP8.5), assuming the reality will likely be somewhere between the two.</p> <p>Our projections suggest current habitats in the ocean around the North Island may become unsuitable if sea-surface temperatures continue to rise.</p> <p>These range shifts become even stronger with increasing severity of climate change. For sperm whales, which are currently abundant off Kaikōura where they support eco-tourism businesses, the predicted distribution changes are even more evident than for blue whales, depending on the climate change scenario.</p> <p>While our results do not predict an overall reduction in suitable habitat that would lead to local extinctions, the latitudinal range shifts are nevertheless bound to have important ecological consequences for New Zealand’s marine ecosystems and the people who depend on them.</p> <h2>How whales maintain ecosystems</h2> <p>Great whales are marine ecosystem engineers. They modify their habitats (or create new ones), to suit their needs. In fact, these activities create conditions that other species rely on to survive.</p> <p>They engineer their environment on several fronts. By feeding in one place and releasing their faeces in another, whales convey minerals and other nutrients such as nitrogen and iron from the deep water to the surface, as well as across regions. This process, known as a “<a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0013255" target="_blank" rel="noopener">whale pump</a>”, makes these nutrients available for phytoplankton and other organisms to grow.</p> <p>This is very important because phytoplankton contributes about <a href="https://education.nationalgeographic.org/resource/plankton-revealed" target="_blank" rel="noopener">half of all oxygen to the atmosphere</a> and also captures <a href="https://www.imf.org/Publications/fandd/issues/2019/12/natures-solution-to-climate-change-chami" target="_blank" rel="noopener">about 40% of all released carbon dioxide</a>. By helping the growth of phytoplankton, whales indirectly contribute to the <a href="https://theconversation.com/tiny-plankton-drive-processes-in-the-ocean-that-capture-twice-as-much-carbon-as-scientists-thought-136599" target="_blank" rel="noopener">natural ocean carbon sink</a>.</p> <p>On top of this, each great whale accumulates about <a href="https://www.arcticwwf.org/the-circle/stories/protecting-the-earth-by-protecting-whales/" target="_blank" rel="noopener">33 tonnes of carbon dioxide in their body</a>, which they take to the ocean floor when they die and their carcass sinks.</p> <p> </p> <figure></figure> <p> </p> <p>Ultimately, the impact of warming oceans on whale distribution is an additional stress factor on ecosystems already under pressure from wider threats, including acidification, pollution and over-exploitation.</p> <h2>A way forward to help whales</h2> <p>Sperm whales are the largest toothed whales (odontocetes) and deep-diving apex predators. They primarily feed on squid and fish that live near the bottom of the sea.</p> <p>Blue whales are baleen whales (mysticetes) and filter small organisms from the water. They feed at the surface on zooplankton, particularly dense krill schools along coastlines where cold water from the deep ocean rises toward the surface (so-called <a href="https://oceanservice.noaa.gov/facts/upwelling.html" target="_blank" rel="noopener">upwelling areas</a>).</p> <p>These differences in feeding habits lead to divergent responses to ocean warming. Blue whales show a more distinct southerly shift than sperm whales, particularly in the worst-case scenario, likely because they feed at the surface where ocean warming will be more exacerbated than in the deep sea.</p> <p>Both species have important foraging grounds off New Zealand which may be compromised in the future. Sperm whales are currently occurring regularly off Kaikōura, while blue whales forage in the South Taranaki Bight.</p> <p>Despite these ecological differences, our results show that some future suitable areas around the South Island and offshore islands are common to both species. These regions could be considered sanctuaries for both species to retreat to or expand their habitat in a warming world. This should warrant <a href="https://environment.govt.nz/assets/Publications/Files/Environmental-Report-Card-Marine-Areas-with-Legal-protection_0.pdf" target="_blank" rel="noopener">increased protection of these areas</a>.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/warming-oceans-may-force-new-zealands-sperm-and-blue-whales-to-shift-to-cooler-southern-waters-188522" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

If you’re renting, chances are your home is cold. With power prices soaring, here’s what you can do to keep warm

<p>If you’re feeling the cold this winter, you’re not alone. About a quarter of all Australians have trouble keeping their homes warm enough in winter. That figure is likely to soar this year, due to poor quality housing and the rapidly escalating energy crisis. </p> <p>Renters are particularly at risk, but our research has shown many home owners are in the same boat as well. We’ve collected data over the last few years on how many Australians have cold homes, find it <a href="https://theconversation.com/forget-heatwaves-our-cold-houses-are-much-more-likely-to-kill-us-83030">difficult to stay warm</a>, and can’t afford their heating bills. </p> <p>What counts as cold? The World Health Organization recommends a <a href="https://www.who.int/publications/i/item/WHO-CED-PHE-18.10">minimum home temperature</a> of 18℃ for health and wellbeing. About a fifth of Australian renters, for example, <a href="https://doi.org/10.1038/s41597-022-01136-5">have cold homes</a>. Our <a href="https://able.adelaide.edu.au/housing-research/research/healthy-housing-cre/cold-in-australian-homes#0">current research</a> has shown this applies to home owners as well, with 26% of people across all housing types unable to stay warm at least half of the time during winter. </p> <p>Australia’s energy crisis is likely to see soaring rates of energy poverty, meaning being unable to keep your home warm or cool enough. Here’s why this is such a problem – and what you can do about it. </p> <h2>Cold homes affect our health</h2> <p>If you’re cold at home, you have a higher risk of developing <a href="https://link.springer.com/article/10.1007/s00484-017-1379-0">respiratory problems</a>and <a href="https://journals.lww.com/jhypertension/fulltext/2014/08000/Stronger_association_of_indoor_temperature_than.8.aspx?casa_token=TFv1eApy3hQAAAAA:9tc6eHiZCAk72mWgrmcgSxQT7kLczUDd7XNpXvNvoIFcMF6pJPSGpORK3SI-Veu4oc994saGXCWuJFBCs3pYN4g">high blood pressure</a>.

Cold can have a flow-on impact on our health system, which is already struggling.</p> <p>Australia’s south-east has had the coldest start to winter <a href="https://thenewdaily.com.au/news/national/2022/06/09/cold-winter-weather-australia/">in decades</a>. Melbourne hasn’t been this cold this early since 1949, while Sydney hasn’t seen these temperatures in early June since 1989.</p> <h2>Double trouble: cold weather and the energy crisis</h2> <p>If you’ve been hit by the recent cold snap, chances are you’ll have been reminded how cold your home can get. This is not a surprise given how badly <a href="https://www.sustainability.vic.gov.au/research-data-and-insights/research/energy-efficiency-and-reducing-emissions/household-retrofit-trials">existing homes</a> and <a href="https://theconversation.com/australias-still-building-4-in-every-5-new-houses-to-no-more-than-the-minimum-energy-standard-118820">new housing</a> perform in keeping an even temperature.</p> <p>The cold has made many people doubly worried, because the energy required to heat our leaky, poorly insulated homes is about to get <a href="https://theconversation.com/expect-more-power-price-hikes-a-1970s-style-energy-shock-is-on-the-cards-183911">very expensive</a>. </p> <p>Early results from <a href="https://able.adelaide.edu.au/housing-research/research/healthy-housing-cre/cold-in-australian-homes#0">our survey</a> of over 350 Australians found 25% of people were experiencing shortages of money to the point they will be unable to adequately heat their homes. One third of our respondents said energy was unaffordable. Some reported making trade-offs, such as skimping on food or healthcare to pay energy bills. </p> <p>These people are experiencing energy poverty, where a household is unable to properly heat or cool their home or face significant financial difficulty doing so. </p> <p>While data about energy poverty in Australia is patchy, we know around 180,000 households <a href="https://vcoss.org.au/wp-content/uploads/2018/11/Persistent-Energy-Hardship-FINAL-Web-Single-Page.pdf">in Victoria</a> had persistent bill payment issues as of 2018, and 45,000 households were consistently unable to heat their homes. </p> <h2>Energy price increases hit lower income households hardest</h2> <p>Lower income households are more at risk from the cold. That’s because they’re more likely to live in homes that are in <a href="https://www.tandfonline.com/doi/full/10.1080/10852352.2016.1197714?casa_token=D_2YbBQ9wRkAAAAA%3A5Z_XqM42cmGunbSwhVJ-EaaHrtV4w3nORhDq9ZoaqAMBx700PldV7_9VVPdAWy7mm2hi3KYLOij3">poor condition</a> and hard to heat. One quarter of low income households told us they struggle to stay warm. Insulation may be a key factor, with 25% of our respondents reporting their rental properties did not have insulation. </p> <p>Insulation matters, because heat escapes homes through <a href="https://www.yourhome.gov.au/passive-design/glazing">single-pane windows</a>, or poorly insulated walls and ceilings. As a result, poorly insulated homes <a href="https://environmentvictoria.org.au/resource/10-tips-warm-house/">cost more to heat</a>. </p> <p>This makes life harder for low income renters, given they have little control over insulation or other home modifications. Worse still, heaters that are cheap to buy are often the most <a href="https://www.climatecouncil.org.au/top-tips-improve-home-energy-efficiency/#:%7E:text=Shoot%20for%20the%20stars%3A%20Top%20tips%20to%20improve%20your%20home's%20energy%20efficiency,-26.11.21%20By&amp;text=Compared%20to%20a%206%2Dstar,amount%20of%20electricity%20we%20use.">expensive to run</a>. </p> <p>While an efficient reverse cycle air conditioner would save money and heat the space better over the longer term, it is often difficult for renters to negotiate installation with property managers or landlords – especially given the intense competition for rentals at present in many cities. That can mean renters will suffer in silence, unwilling to ask for something that will make their lives better.</p> <h2>What can renters do?</h2> <p>Low income renters face real threats from energy poverty this year. While we need systemic change to improve the outlook for Australia’s renters, there are low-cost DIY ways to improve how <a href="https://www.yourhome.gov.au/">your house retains heat</a> this winter. </p> <p>The first step: check your current heating appliances are working efficiently. Many people don’t clean the filters on their reverse cycle air conditioners. This makes them less efficient, and can drive up energy bills.</p> <p>Poorly sealed windows and doors make it hard to stay warm. </p> <p>Using <a href="https://home.howstuffworks.com/home-improvement/heating-and-cooling/insulated-curtains.htm">thermal curtains</a>, and keeping them closed makes a big difference. Putting a piece of plywood or even a scarf between the curtain rail and the wall to make a <a href="https://environmentvictoria.org.au/2011/07/05/take-the-chill-out-of-winter-with-diy-pelmets/">DIY pelmet</a> also helps keep the heat in. If you have single glazed windows, consider <a href="https://renew.org.au/renew-magazine/buyers-guides/window-buyers-guide/">window films</a> as a way to improve performance for a fraction of the cost of double glazed windows.</p> <p><a href="https://blog.csiro.au/draught-proof-house/">Sealing the cracks</a> around windows, under doors and around the wider home is also important. Silicon or expanding foam can be used for gaps and cracks. Draughts under doors can be stopped with door seals or door snakes.</p> <p>Close the doors to your bathroom, laundry and other rooms not in use to keep the heat where you need it most. Hanging a blanket over a doorway can also be a cheap way to seal off a room and concentrate heat.</p> <p>It’s also worth checking what rebates and concessions your state government or council is offering. These might include energy efficiency improvements or extra help with heating costs. If you’re renting, your home must meet <a href="https://www.energy.vic.gov.au/energy-efficiency/minimum-rental-standards">minimum standards</a>, so make sure you check what you are entitled to as these vary by state. </p> <p>Everyone deserves a warm home. Our health and well-being depend on it. Building new, energy efficient homes is only part of the answer.

9 little winter fashion rules you need for staying warm and stylish

<p><strong>Pair skirts with knits</strong></p> <p>Instead of the typical blouse, pair your skirt with a cute knit this winter. You can layer a thin t-shirt or tank under your knit to ensure even more warmth. Celebrity stylist Cristina Ehrlich told <em>In Style </em>to pick your fit according to your height. “On the shorter side? Choose a more fitted sweater. If you have some height, the long shawl style is perfect,” according to Ehrlich.</p> <p><strong>Layer, layer, layer</strong></p> <p>Ray Lowe, fashion market writer for <em>refinery29.com</em>, recommends wearing a thin shirt under your knit and then top off the look with a stylish coat. This way, when you get to the warm indoors you can take off your layers in case you feel too hot.</p> <p><strong>Swap out thin tights for a thicker material</strong></p> <p>Try wearing fleece lined tights or leggings underneath your dresses, skirts and even pants. Fleece lined tights and leggings are still relatively thin material, so you won’t look too bulky, but you will be much warmer.</p> <p><strong>Rock the faux fur</strong></p> <p>Turn heads with a stylish faux fur top layer such as a coat or vest. <em>Glamour </em>recommends keeping the rest of the outfit simple with a solid knit and pants.</p> <p><strong>Layer with a turtleneck</strong></p> <p>Turtlenecks are only for the ski slopes: wear a turtleneck under your blouse to keep you extra warm. Add colour to your outfit with a stand-out turtleneck, or keep the look more neutral. Depending on how tight your blouse fits, stay even warmer with a thicker material turtleneck such as wool.</p> <p><strong>Add colour with hats and gloves</strong></p> <p>Add pops of colour to your outfit with colourful hats, gloves and other winter accessories. That way you can still make a fashion statement when you bundle up to go outside. Stylist Elizabeth Stewart, told <em>In Style</em> that she recommends wearing a thick black shawl with bright knit gloves and hats.</p> <p><strong>Wear ribbed clothes</strong></p> <p>“Trapping pockets of heat in your clothes while lengthening the lines of your limbs, these cottons are indispensable in a wintertime wardrobe,” Connie Wang, fashion features director at <em>refinery29.com</em> wrote on the site. Wear ribbed shirts and tights under your knits and dresses.</p> <p><strong>Layer with silk</strong></p> <p>Silk is an extremely warm material and since it’s very thin, it’s easy to layer underneath your winter clothes. Wear it under jackets, knits and dresses for another layer of insulation while still making a fashion statement.</p> <p><strong>Sport knee-high boots</strong></p> <p>Keep your feet and legs warm while wearing a skirt or dress with knee high boots. Celebrity stylist Miranda Almon recommended to <em>In Style</em> to go up half a size with your boots. “Going a half size up allows room for wearing thicker socks over tights,” Almond said.</p> <p><em><span id="docs-internal-guid-e4815da9-7fff-8152-7b32-db4457da9fd7">Written by Morgan Cutolo.

8 essential rules for working out in the winter

<p><strong>Baby, it’s cold outside</strong></p> <p>It can be tough to find the motivation to do an outdoor workout once winter strikes with low temperatures, wind chill, rain and dark nights. However, don’t let the cold weather deter you from accomplishing your fitness goals – even in the winter.</p> <p>Read on down below and follow our expert tips to stay fit, warm and motivated this winter.</p> <p><strong>Dress for the weather</strong></p> <p>Workout clothes are much more than just for aesthetics – they’re designed for the type of exercise you’re doing as well as the climate and weather that you’re training in. “The most important elements to take into consideration for outdoor workouts are wind chill and precipitation,” says Kaitlyn Noble, a personal trainer. Layers will protect you on a cold, wind-free day, however, wind chills can easily penetrate thinner items of clothes, which is why wind-resistant materials are so crucial. And of course, if your clothes are wet, you’ll have no protection from the frigid temperature, so be sure to wear a water-resistant outer layer when it’s raining. Your workout wear should always be water wicking in the cold too, like with thermal leggings, since sweat-soaked clothes can freeze in really cold conditions.</p> <p><strong>Active warm-ups</strong></p> <p>“Imagine a rubber band… it’s flexible, bendy and pulls right back to its shape. Now imagine that same rubber band, but frozen. If you try to pull too hard before it’s thawed out, it’ll snap,” explains trainer Ashley Wilking. Your muscles are like rubber bands, you need to gradually warm them up to prevent injury.</p> <p>Noble suggests starting to heat up your larger muscles, like quads and hamstrings, with light stretching, jumping jacks and lunges indoors before heading outside. If you’re commuting to a class or gym, consider speed walking to get your heart rate up.</p> <p><strong>Don’t skip your cool down</strong></p> <p>Make sure to give your body time to cool down and stretch before you rush out of your workout class or the gym. “You don’t want to go from a heart-pumping, sweat-drenched working session, straight into the cold or a sedentary position, like sitting at a desk,” says Wilking. Stretching post-workout is crucial – but particularly after a cold-weather workout to keep your body safe from injury.</p> <p><strong>Protect your head and hands</strong></p> <p>While only about 10 percent of your body heat escapes from your head, as opposed to 70 percent as previously believed (just one of the many myths about the human body), wearing a hat in cold weather – especially when doing outdoor activities, like biking, running and even on your daily stroll – is still important. “Choose a hat made of a warm, breathable material that also protects your ears,” says Noble. Your hands are another body part that are likely to feel the chill, which means gloves are a must. Pro tip: Choose a pair with touchscreen fingers, so you’re not taking them off and on to change music.</p> <p><strong>Hydrate</strong></p> <p>You may feel like you sweat less in cold weather, but don’t be fooled, you still need to drink up. Dehydration increases your risk of injury significantly and will slow down your performance. Stay hydrated by drinking room temperature water before, during and after your workout. “Many people find that cold water is harder to drink, so by keeping your water room temperature you can hydrate more easily,” says Amanda Kloots, creator of The Rope and The Dance studios.</p> <p><strong>Choose reflective gear</strong></p> <p>Since winter months also mean less daylight, your workout is more likely to happen in the dark. Make yourself visible to cars, cyclists and other pedestrians by wearing reflective items, like shoes, backpacks and jackets.</p> <p><strong>Don’t forget sun protection</strong></p> <p>Just because it’s cold doesn’t mean you can’t get burnt. Don’t skimp on the sunscreen. Continue wearing sun protection during daylight hours, regardless of the temperature.</p> <p><em><strong>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/fitness/8-essential-rules-for-working-out-in-the-winter" target="_blank" rel="noopener">Reader’s Digest</a>.</strong></em></p> <p><em>Image: Shutterstock</em></p>

One-year-old receives a heart-warming letter from Windsor Castle

<p><em>Image: The Sun</em></p> <p>A young girl has received a letter from Windsor Castle after dressing up as The Queen for Halloween.</p> <p>One-year-old Jalayne Sutherland caught royal attention after donning an adorable double-breasted overcoat with a matching hat, a white wig and pearls around her neck.</p> <p>She was photographed by her mum, Katelyn Sutherland, standing alongside her family corgis. Katelyn, from Ohio, America, sent the photograph to The Queen on a whim - and said she did not expect to receive a reply.</p> <p>She said, "The biggest inspiration for the outfit was the fact that our dogs are our daughter's best friends."</p> <p>“We wanted to do something where they could all be included together. We are most definitely fans of the Royal family and truly admire how the Queen walks by faith."</p> <p>Katelyn said her daughter's costume was met with lots of praise as she took her trick-or-treating on Halloween this year.</p> <p>She added, “While walking around on Halloween we received many, many compliments but my favourite reactions were when people bowed to her or did the royal wave and said, ‘Your Majesty!’”</p> <p>The letter, from the Queen's lady in waiting for the Hon Marry Morrison, said, “The Queen wishes me to write and thank you for your letter, and for the photograph you thoughtfully enclosed."</p> <p>“Her Majesty thought it kind of you to write to her, and The Queen was pleased to see the photograph of your daughter, Jalayne, in her splendid outfit."</p> <p>“Her Majesty hopes you all have a very Merry Christmas, and I am enclosing a little information about the Royal Pets, which Jalayne might like to have.”</p>

<p>Australian researchers found during an extreme heatwave that backyard gardens lowered land surface temperatures by five to six degrees Celsius more than similar non-vegetated areas.</p> <p>Hot summers can cause city temperatures to soar one to three degrees higher than surrounding areas, creating “<a rel="noreferrer noopener" href="https://www.smithsonianmag.com/science-nature/city-hotter-countryside-urban-heat-island-science-180951985/" target="_blank" aria-label=" (opens in a new tab)">urban heat islands</a>” due to excess concrete, people, air conditioning, machinery and the resulting local climate.</p> <p>Not only can this be uncomfortable, and even unlivable, it can also place a significant burden on <a rel="noreferrer noopener" href="https://www.scientificamerican.com/article/heat-wave-health/" target="_blank" aria-label=" (opens in a new tab)">public health</a>.</p> <p>Green infrastructure and other nature-based solutions are proposed as cost-effective, sustainable approaches to mitigating the impacts of climate change. </p> <p>“Urban trees in particular are an effective tool for reducing land surface and air temperatures for entire suburbs, and even cities,” says researcher Alessandro Ossola from Macquarie University, Australia.</p> <p>“But as yet we don’t know much about their localised effects, particularly in the places where cooling is most important – our residential neighbourhoods – and when needed the most – during extreme heatwave events.”</p> <p>To investigate this, Ossola and colleagues from the university’s collaborative <a rel="noreferrer noopener" href="https://www.mq.edu.au/research/research-centres-groups-and-facilities/secure-planet/centres/centre-for-green-cities" target="_blank" aria-label=" (opens in a new tab)">Smart Green Cities</a> hub analysed thermal mapping data collected from an aircraft in summer 2017 at the peak of a three-day long 40-degree heat wave in Adelaide.</p> <p>The results, <a rel="noreferrer noopener" href="https://research-management.mq.edu.au/ws/portalfiles/portal/113138181/Urban_trees_and_peoples_yards_mitigate_extreme_heat_in_Western_Adelaide_28.01.2020.pdf" target="_blank" aria-label=" (opens in a new tab)">published </a>in an online report, were surprisingly positive. </p> <div class="newsletter-box"> <div id="wpcf7-f6-p35716-o1" class="wpcf7"> <p style="display: none !important;"> </p> <!-- Chimpmail extension by Renzo Johnson --></div> </div> <p>“We found that the humble home garden is more than pulling its weight when it comes down to urban cooling,” says Ossola. “Although they only cover about 20% of urban land, domestic yards account for more than 40% of tree cover and 30% of herbaceous cover, in the form of grass.” </p> <p>The tree canopy cover is notably more than typical parks or other urban green areas which tend to have more grass, and the cooler temperatures were particularly pronounced in the hottest suburbs that don’t enjoy cooling sea breezes.</p> <p>The researchers estimate that increasing green foliage in residential gardens could reduce local heat by several degrees Celsius. </p> <p>On the other hand, they calculated that removing existing vegetation through urbanisation, infill and densification could increase local land surface temperatures by three to four degrees, particularly during the day and for the most vulnerable communities.</p> <p>The considerable, localised cooling benefits of backyard gardens have important implications for policy, which needs to account for extreme temperatures in urban planning, Ossola says.</p> <p>“Our results clearly indicate that encouraging, protecting and expanding urban greening on private land is a simple, effective means of mitigating the negative effects of climate change on cities and people.</p> <p>“However this is a strategy that needs to begin now: urban forests don’t grow quickly, and we need to be encouraging low-water use herbaceous cover as a stopgap until a large array of shade trees can take over the job of green cooling.”</p> <p><strong><em>The Royal Institution of Australia has an education resource based on this article.</em></strong> You can access it <a rel="noreferrer noopener" href="https://education.australiascience.tv/backyard-helps-reduce-global-warming/" target="_blank">here</a>.</p> <p><!-- Start of tracking content syndication.

Even if we halt global warming, local climates will change – and we need new experiments to understand how

<p>There’s a big question mark over whether the world will keep global warming below the limits set out in the Paris Agreement. But even if we do, the climate will keep evolving – and society needs to prepare for this.</p> <p>At the moment, climate models don’t tell us much about a future world in which temperatures have stabilised. As our <a href="https://dx.doi.org/10.1038/s41558-021-01225-0">research</a> published today argues, new model experiments are needed to close this knowledge gap and better understand the challenges ahead.</p> <p>For example, in southern Australia, climate change has already caused a <a href="https://theconversation.com/climate-change-is-likely-driving-a-drier-southern-australia-so-why-are-we-having-such-a-wet-year-172409">trend</a> towards less rain and more frequent and prolonged drought. If the global climate stabilises, we expect this drying trend to reverse, which could ease future strains on water supply in this region. This would in turn affect urban planning, agriculture and water policy.</p> <p>The new models we’re proposing would enable more useful climate projections aligned with the Paris Agreement targets – and better prepare society for a warmer, but more stable, global temperature.</p> <h2>Targeting a stable climate</h2> <p>Under the landmark Paris Agreement, the world is aiming to keep global warming well below 2℃ compared with <a href="https://theconversation.com/what-is-a-pre-industrial-climate-and-why-does-it-matter-78601">pre-industrial</a> times, and preferably below 1.5℃.</p> <p>The world is warming at a rate of around 0.25℃ per decade and is already about <a href="https://www.globalwarmingindex.org/">1.2℃ warmer</a> than in pre-industrial times.</p> <p>This warming won’t stop until net greenhouse gas emissions are <a href="https://www.carbonbrief.org/explainer-will-global-warming-stop-as-soon-as-net-zero-emissions-are-reached">near zero</a>. If we don’t greatly reduce emissions in the next decade, we will warm the planet beyond 1.5℃.</p> <p><img src="https://images.theconversation.com/files/433635/original/file-20211124-24-c6db8t.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /> <span class="caption">The world has warmed and will continue to warm in the coming decades but the Paris Agreement targets a stabilised future climate with low global warming.</span> <span class="attribution"><span class="source">Author provided</span></span></p> <p>To date, climate simulations used to examine the implications of the Paris Agreement either assume warming continues beyond 1.5℃ and 2℃, or only examine a short period after warming has stopped. This is because most of these simulations were not specifically designed to analyse global warming levels linked to the Paris Agreement, and mostly focus only on what will happen this century.</p> <p>If we manage to stabilise global temperatures, other aspects of Earth’s climate would continue to change. Studies based on <a href="https://journals.ametsoc.org/view/journals/bams/100/12/bams-d-19-0068.1.xml">long model experiments</a> suggest ocean and land temperatures continue to evolve for centuries after global warming slows. That’s because the ocean warms at a slower rate than the land, and warming water can take hundreds, and even thousands, of years to mix into the deep ocean.</p> <p>Even after the global temperature stabilises at the levels set out in the Paris Agreement, many ocean areas would likely warm by at least a further 0.5℃. Meanwhile some land areas would cool by <a href="https://pursuit.unimelb.edu.au/articles/how-fast-the-planet-warms-will-be-crucial-for-liveability">at least 0.5℃</a>.</p> <p>The ocean takes time to catch up – and as it does, land temperatures have to fall to maintain the same global average temperature.</p> <p>In addition, if global temperature remained near-constant, rainfall patterns would likely <a href="https://www.nature.com/articles/s41558-019-0397-9">change</a>. In some subtropical regions, such as southern Australia, this might mean a reversal of the drying trends we’ve seen over the past few decades.</p> <p><img src="https://images.theconversation.com/files/433830/original/file-20211125-27-1wn5fny.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="man stands on ice looking at Arctic scene" /> <span class="caption">The ocean takes time to catch up to global warming.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>New models are needed</h2> <p>Clearly, we need new experiments to model Earth’s climate if warming is stabilised at 1.5℃. Our <a href="https://dx.doi.org/10.1038/s41558-021-01225-0">new paper</a> proposes a framework for designing these experiments.</p> <p>Our framework differs from the approach taken by various climate modelling groups around the world in recent decades.</p> <p>These groups have all used the same projection of greenhouse gas concentrations in the atmosphere, and how they change through time. This <a href="https://gmd.copernicus.org/articles/9/3461/2016/gmd-9-3461-2016.pdf">approach</a> allows for comparison of climate projections between models for the same greenhouse gas scenarios.</p> <p>But because each group fed this projection into their own climate model – each with their own characteristics – each produced different predictions for how much global warming would occur. Also, these model simulations are mostly run only to 2100, and so represent a world that’s continuing to warm and hasn’t had time to stabilise.</p> <p>Instead, our framework involves reaching the same level of global warming across a range of climate models. This would be achieved by “turning off” the carbon emissions used in various climate models at different times.</p> <p>So, a climate model that warms more strongly in response to greenhouse gas emissions would have its carbon emissions “turned off” earlier, relative to a slower warming model. This would provide a group of climate model simulations at around the same level of global warming.</p> <p>Stopping carbon emissions will <a href="https://www.carbonbrief.org/explainer-will-global-warming-stop-as-soon-as-net-zero-emissions-are-reached">cause</a> global warming to slow and, eventually, stop. Running these simulations for up to 1,000 years after carbon emissions stop will allow us to investigate and understand the effects of climate stabilisation in line with the Paris Agreement.</p> <p>A few global modelling centres have started running simulations following similar frameworks, including Australia’s CSIRO. We invite other climate modelling centres to join us in our experiments, and help policymakers and societies better prepare for a warmer world.<!-- Below is The Conversation's page counter tag.
