The ozone layer is necessary to helping life survive on Earth. It acts like atmospheric sunscreen, which is why scientists keep a close eye on an ozone hole that appears seasonally over Antarctica.
This year’s hole “is one of the largest and deepest in recent years,” the European Space Agency (ESA) said in a statement this week. The ozone layer protects the inhabitants of Earth from ultraviolet radiation from the sun.
The size of the hole fluctuates and reaches its maximum size sometime in September or October every year. The Copernicus Sentinel-5P satellite is tasked with watching the ozone hole. The German Aerospace Center crunched the data and determined the hole has hits its peak for 2020 and ozone levels are set to recover by the end of the year.
The 2020 hole reached a size of about 9.6 million square miles (25 million square kilometers) in early October. ESA said this size was comparable with the holes that formed in 2015 and 2018.
An image released with the statement shows the hole extending across most of Antarctica and a video lets you track the changes from late September through the middle of October…Read more>>
