You may have heard about the hole in the ozone layer, which hovers over Antarctica. It has shrunk over time thanks to policies that curbed the use of ozone-depleting chemicals. In the nearly 40 years that NASA has kept track, it has never been smaller. That's the good news.
Polar stratospheric clouds activate the chemicals that deplete the ozone layer. NASA

The United Nations suggests that climate change is not just the defining issue of our time, but we are also at a defining moment in history. Weather patterns are changing and will threaten food production, and sea levels are rising and could cause catastrophic flooding across the globe. Countries must make drastic actions to avoid a future with irreversible damage to major ecosystems and planetary climate.

Tierra del Fuego is at the southernmost tip of South America and is sometimes known as the "end of the world." This windswept part of Argentina is home to seven penguin colonies which breed, nest and feed in the area.

The climate crisis has caused Japanese cherry blossoms to bloom in October and sped the arrival of spring in much of the U.S. But it turns out that humans aren't the only animals who can trick plants into flowering early.

At least 84 people were killed when Cyclone Amphan walloped India and Bangladesh Wednesday, bringing "war-like" destruction to the city of Kolkata in the Indian state of West Bengal, The Guardian reported.
A colony of king penguins in Antarctica emit so much nitrous oxide, or laughing gas, in their poop that researchers went a little "cuckoo," while studying them, according to Agence France Presse, which reported on a new study published in the journal Science of the Total Environment.

Rifugio Guide del Cervino is a bar and restaurant atop the Plateau Rosa, a glacial ridge in the Italian Alps. Or at least, it was. Climate change is moving it inexorably toward Switzerland as the glacier on which it sits steadily melts.
Mobile Border<p>The Rifugio has 40 guest beds and is a <a href="http://www.cerviniaicons.com/food/2018/06/rifugio-guide-del-cervino/" target="_blank">popular destination for climbers attempting the Breithorn</a> (4,164 meters, or 13,661 feet), neighbor to the Matterhorn on the Swiss border. But that's as close to Switzerland as Trucco wants his restaurant to get.</p><p>For now, COVID-19 restrictions mean the Rifugio is closed. <a href="https://www.bbc.co.uk/news/world-europe-52701621" target="_blank">Italy is starting to lift its coronavirus lockdown</a>, but with bars among the businesses allowed to open, some people say <a href="https://www.skiresorts.net/skiing-social-distancing/" target="_blank">social distancing in ski resorts</a> may prove hard to implement.</p><p>In 2009, <a href="https://www.newscientist.com/article/dn16854-climate-changes-europes-borders-and-the-worlds/" target="_blank">Italy and Switzerland agreed their border should be mobile</a>, shifting to accommodate changes caused by glacial melting. Movements are monitored using GPS sensors allowing the <a href="https://glacierhub.org/2020/04/30/as-the-climate-shifts-a-border-moves/" target="_blank">border to be redrawn</a> as the ice moves.</p>
Sea Levels<p>Climate change is affecting other borders around the world. In the southern U.S., <a href="http://mississippiriverdelta.org/our-coastal-crisis/land-loss/" target="_blank">rising sea levels</a> and the canalization of the Mississippi river are the culprits. Since the 1930s, Louisiana has seen more than half a million hectares of its coastal territory disappear under the waves.</p><p>As Pulitzer Prize-winning author Elizabeth Kolbert put it in<a href="https://www.newyorker.com/magazine/2019/04/01/louisianas-disappearing-coast" target="_blank"> a recent article for the New Yorker</a>: "If Delaware or Rhode Island had lost that much territory, the U.S. would have only forty-nine states. Every hour and a half, Louisiana sheds another football field's worth of land."</p><p>Shrinking glaciers are one of the most visible demonstrations of the effects of global warming. The U.S. National Oceanic and Atmospheric Administration says the amount of ice lost since 1980 is equivalent to <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-glacier-mass-balance" target="_blank">removing a 24-meter (79-foot) slice off the top of each glacier</a>.</p><p><a href="http://climateandlife.columbia.edu/2017/05/08/the-glaciers-are-going-why-this-matters/" target="_blank">More than one-sixth of the world's population</a>, particularly in China, India and other Asian countries, depend on glaciers for drinking and irrigation water, according to scientists at Columbia University.</p><p>Global temperatures are estimated to have risen by at least 1°C (33.8 degrees F) <a href="https://www.ipcc.ch/sr15/chapter/spm/" target="_blank">above pre-industrial levels</a>, and experts warn urgent action is needed to curb emissions. A rise above 1.5°C (34.7 degrees F) will cause <a href="https://www.nature.com/articles/nature23878" target="_blank">glaciers in Asia</a>, for example, to shrink by two-thirds by the end of the century.</p>

When your body gets too hot, you may experience a heat-related illness such as heat exhaustion or heat stroke. Such illnesses can be dangerous. In fact, on average, there are more heat-related deaths in the U.S. each year than hurricane- or flood-related fatalities combined.
But heat exhaustion and heat stroke are preventable. Read on for some do's and don'ts.
