On February 20, 2024, Antarctica reached its seasonal minimum ice extent, hitting near-historic lows for the third consecutive year. This continues a worrying trend that may indicate a long-term climatic shift, with significant environmental implications. Sea ice coverage reached its seasonal minimum ...
but there was less indication of it reaching a new record low. The predicted sea ice area (SIA) and sea ice extent (SIE) for February 2024 were 1.441 million square kilometers and 2.105 million square kilometers, respectively, slightly higher than the historic lows observed in...
How does internal variability influence the ability of CMIP5 models to reproduce the recent trend in Southern Ocean sea ice extent? Cryosphere 7, 451–468 (2013). Article Google Scholar Ding, Q., Steig, E. J., Battisti, D. S. & Küttel, M. Winter warming in West Antarctica caused ...
In 2023, sea ice extent fell to record lows, reaching unprecedented values for both the summer minimum, winter maximum and intervening freeze‐up period. Here, we show that the extreme values observed were truly remarkable within the context of the satellite record, despite the challenge of ...
BEIJING, April 19 (Xinhua) -- The extent of sea ice in the Antarctic hit a record low in February, the second such event within five years, a new Chinese study shows. The study, published on Tuesday in the journal Advances in Atmospheric Sciences, revealed that on Feb. 25, a few days...

For example, during an El Niño/SAM– combination, the northward sea-ice transport was reduced while heat advection from the subtropics to the Southern Ocean increased, which resulted in reduced sea-ice extent in the Indian sector as sea ice was compacted along the Antarctic coast. Our ...
In the context of global warming, the question of why Antarctic sea ice extent (SIE) has increased is one of the most fundamental unsolved mysteries. Although many mechanisms have been proposed, it is still unclear whether the increasing trend is anthropogenically originated or only caused by inte...
Changes in the extent of Antarctic sea-ice are difficult to quantify for the pre-satellite era. The available direct data are sparse. A substantially larger set of proxy records based on whaling positions indicated a large shift in whaling positions between the 1930s to 1950s compared with whal...
