Nov. 21, 2023 Despite public perception, the Antarctic ozone hole has been remarkably massive and long-lived over the past four years; researchers believe chlorofluorocarbons (CFCs) aren't the only things to ...
June 3, 2021 Glaciologists analyzed Antarctic ice cores to understand the continent's air temperatures during the most recent glacial period. The results help understand how the region behaves during a major ...
Feb. 5, 2024 The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a ...
May 5, 2021 Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a new study. Overall, sea ice has been on the rise for about ...
Sep. 7, 2022 Of all the oceans on Earth, the Southern Ocean does the lion's share at slowing the pace of climate change by absorbing most of the excess heat trapped in the planet's atmosphere, say ...
June 16, 2021 Ozone is a pollutant at ground level, but very high in the atmosphere's 'ozone layer,' it absorbs damaging ultraviolet radiation. Past studies have examined ozone levels in the ...
Mar. 28, 2022 Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak ...
Feb. 7, 2023 The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high ...
Aug. 8, 2023 Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers ...
Nov. 23, 2021 New research has shed light on a sudden cooling event 34 million years ago, which contributed to formation of the Antarctic ice ...
