Greater Antarctic snowfall increases future ice loss and sea level rise

December 18th, 2012 by Potsdam Institute for Climate Impact Research

Earlier research suggested the Antarctic ice sheet might grow under climate change because global warming leads to more precipitation as warmer air holds more moisture. New research finds that stronger snowfall increases future ice discharge from Antarctica. The paper “Increased future ice discharge from Antarctica owing to higher snowfall” published in Nature shows that a […]

Greenland and Antarctica ice loss accelerating

November 29th, 2012 by University of Washington

Forty-seven research scientists from 26 laboratories have reconciled their measurements of ice sheet changes in Antarctica and Greenland during the past two decades and found that ice has been lost faster during the last decade. The results, published in the paper “A Reconciled Estimate of Ice-Sheet Mass Balance” in the journal Science, roughly halve the […]

Ocean acidification dissolving shell of planktonic Southern Ocean snails

November 25th, 2012 by British Antarctic Survey

A paper “Extensive dissolution of live pteropods in the Southern Ocean” published online in Nature Geoscience suggests that the effects of ocean acidification on marine ecosystems are beginning to emerge. Dr Geraint Tarling, of the British Antarctic Survey, and colleagues, examined shells collected from a pteropod, Limacina helicina antarctica, (a planktonic marine snail) in the surface […]

Drop in atmospheric carbon dioxide led to Antarctic ice sheet formation

December 5th, 2011 by Purdue University

A drop in carbon dioxide appears to be the driving force that led to the Antarctic ice sheet‘s formation, according to a recent study led by scientists at Yale and Purdue universities of molecules from ancient algae found in deep-sea core samples. The key role of the greenhouse gas in one of the biggest climate […]
