Antarctic sea-ice models improve for the next IPCC report

University of Washington The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different inputs to run simulations of what a future world might look like, and can be so big — in some cases, lines of code in the millions — they…

Icebergs delay Southern Hemisphere future warming

Institute for Basic Science New research, published today in the journal Nature Climate Change, has found that Antarctic icebergs can weaken and delay the effect of Global Warming in the Southern Hemisphere. Unabated Global Warming threatens the stability of the Antarctic ice sheet. Recent observations reveal a rapid thinning of the Pine Island and Thwaites…

Antarctic sea ice is declining dramatically

A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the rates seen in the Arctic Claire L.
