NASA | Big Ozone Holes Headed For Extinction By 2040
The next three decades will see an end of the era of big ozone holes. In a new study, scientists from NASA Goddard Space Flight Center say that the ozone hole will be consistently smaller than 8 million square miles by the year 2040....

Warm Winter Air Makes for a Small Ozone Hole
NASA and NOAA scientists work together to study the ozone layer, monitoring the hole over Antarctica as it fluctuates with the seasons. This year, the ozone hole's annual maximum set a record -- the smallest it's been since 1988. The...

NASA | OIB Flights South 2014: A Sea Ice Mystery
Where’s it coming from? With global average temperatures rising, it would be natural to assume that total quantities of sea ice would be falling. But it’s not. Scientists have begun to observe sea ice increases around Antarctica, and the...

Unusual Winds Drive a Small 2019 Ozone Hole
Every year, NASA and NOAA track the hole in the ozone layer over Antarctica as it grows to its annual winter maximum. This year, the hole was smaller than expected, due to an unusual weather pattern in the stratosphere. Music credit:...

NASA Finds Local Lockdowns Brought Global Ozone Reductions
As the coronavirus pandemic slowed global commerce to a crawl in early 2020, emissions of nitrogen oxides (NOx) – which create ozone, a danger to human health and to climate – decreased 15% globally with local reductions as high as 50%,...

2016 Antarctic Ozone Hole Meets Scientist Expectations
The hole in Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric...
