Our knowledge of dwindling sea ice coverage in the Arctic Ocean comes mostly through satellites, which have imaged sea ice from above since 1979. The University of Washington Pan-Arctic Ice Ocean and ...
Data from robotic drifters explain mysterious holes in Antarctic sea ice（图）
robotic drifters mysterious holes Antarctic sea ice
2019/10/28
Winter ice on the surface of Antarctica's Weddell Sea sometimes has an enormous hole called a polynya. A polynya that appeared in 2016 and 2017 offered a unique opportunity for oceanographers to monit...
Instability in Antarctic ice projected to increase likelihood of worst-case sea level rise（图）
Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...
Scientists solve long-standing mystery:Why atmospheric carbon dioxide was lower during ice ages（图）
Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...
New findings from the University of Michigan explain an Ice Age paradox and add to the mounting evidence that climate change could bring higher seas than most models predict.The study, published in Na...

The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by ...
Sea-level rise from Antarctic ice sheet could double
Sea-level rise Antarctic ice sheet double
2016/4/13
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue ...
