This study shows that the most intense atmospheric rivers induce extremes in temperature, surface melt, sea-ice disintegration, or large swells that destabilize the ice shelves with 40% probability.Read More →

PNAS
This study uses GMSLR modeling that can handle emission scenarios flexibly to establish the link between pledged NDC emissions and GMSLR until 2300, thus highlighting the longer-term climate change implications of current climate mitigation efforts.Read More →

A 40-y Record Reveals Gradual Antarctic Sea Ice Increases Followed by Decreases at Rates Far Exceeding the Rates Seen in the Arctic

Proceedings of the National Academy of Science of the United States of America (PNAS)
This analysis of 40 years of satellite records reveals a gradual increase in Antarctic sea ice which reversed in 2014. The rapid rates of decrease far exceed those in the Arctic and reduced the Antarctic sea ice to their lowest values in the record. Read More →

Non‐annular atmospheric circulation change induced by stratospheric ozone depletion and its role in the recent increase of Antarctic sea ice extent
