The ozone layer is a layer of gas in the stratosphere that absorbs most of the sun’s harmful ultraviolet radiation—rays that are associated with skin cancer, cataracts, and a host of environmental issues. The infamous ozone holes occur because of the thinning of this layer of air.
The Copernicus Atmosphere Monitoring Service (CAMS) said that it was tracking the record-sized hole on April 6, with researchers saying that it had been caused by unusually low temperatures above the North Pole. Scientists at the time predicted that the hole would close in a matter of weeks, and that appears to be what has just happened.
Just as suddenly as it first formed, a record-breaking ozone hole has healed. The largest ozone hole to ever open up over the Arctic is now closed, after first opening up earlier this spring, leaving a huge positive impact on environment.
