    Record Ozone Hole Over the Arctic Has Closed

    Record Ozone Hole Over the Arctic Has Closed

    An unusual phenomenon happened in March and April when an enormous hole in the ozone layer formed over the Arctic. Last week, though, scientists tracking the hole noticed that it has closed, as CNN reported. Unlike the infamous hole in the ozone over Antarctica, which was caused by overuse of now illegal chemicals containing chlorofluorocarbons, […]

    Seals Are Helping Scientists Map the Future of Antarctic Krill

    Seals Are Helping Scientists Map the Future of Antarctic Krill

    The western Antarctic Peninsula is one of the fastest warming places on Earth. But how will that impact the unique wildlife that call it home? To find out, researchers tracked the movements of krill-eating crabeater seals in the western Antarctic Peninsula (WAP) to build a model of the future distribution of krill, an important food […]

    Record Ozone Hole Forms Over Arctic

    Record Ozone Hole Forms Over Arctic

    A record-sized hole has opened in the ozone layer over the Arctic, The Guardian reported Tuesday. While both poles lose some ozone during their winters, the Arctic tends to lose much less than Antarctica, where the larger and more famous ozone hole is located, the European Space Agency (ESA) explained. This year’s anomaly is the […]

    Antarctica Experiences First Known Heat Wave

    Antarctica Experiences First Known Heat Wave

    By Richard Connor Scientists have recorded Antarctica’s first documented heat wave, warning that animal and plant life on the isolated continent could be drastically affected by climate change. Australian Antarctic Program researchers recorded the heat wave event at Casey research station in East Antarctica during the 2019-2020 southern hemisphere summer. Findings by the team were […]

    Human Cooperation Can Restore Climate Patterns: The Case of the Ozone Layer and the Southern Jet Stream

    Human Cooperation Can Restore Climate Patterns: The Case of the Ozone Layer and the Southern Jet Stream

    Emissions from the chlorofluorocarbons and hydrochlorofluorocarbons used as refrigerants and aerosols didn’t just burn a hole in the ozone layer. They also shifted the Southern Hemisphere’s jet stream south towards Antarctica. Now, a study published in Nature Wednesday found that the 1987 Montreal Protocol banning those substances wasn’t just successful in helping to repair the […]
