New findings about the ozone hole over Antarctica.
Despite having an area nearly equal to that of North America, the ozone hole over Antarctica is currently the second smallest in the past two decades.
This is the latest announcement from scientists at the U.S. National Oceanic and Atmospheric Administration (NOAA) and the U.S. National Aeronautics and Space Administration (NASA), released on October 24th, regarding the results of their research on the vulnerabilities in Earth's protective "shield."

Scientists from the two agencies said the ozone hole over Antarctica, which formed in September and October, has reached a size of 21.32 million square kilometers, nearly the combined area of three countries: the United States, Mexico, and Canada. Meanwhile, the largest ozone hole recorded to date was 29.9 million square kilometers, recorded in 2000.
According to American scientists, the ozone layer, which protects Earth from dangerous ultraviolet rays, began to develop holes in the 1980s due to chlorofluorocarbon (CFC) emissions. This type of gas has now been largely eliminated thanks to an international convention signed in 1987.
