NASA, the National Aeronautics and Space Administration, says that Earth’s ozone hole is now the smallest it’s been since it’s discovery. Abnormally warm weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October 2019, resulting in the smallest ozone hole since 1982, NASA and NOAA scientists reported.

“It’s great news for ozone in the Southern Hemisphere,” said Paul Newman, chief scientist for Earth Sciences at NASA’s Goddard Space Flight Center in a statement on NASA’s website.
“But it’s important to recognize that what we’re seeing this year is due to warmer stratospheric temperatures. It’s not a sign that atmospheric ozone is suddenly on a fast track to recovery.”
