There is now no doubt that Antarctica’s ice sheet is melting – and the melting is accelerating. Res. Sch. Christopher Harig and Prof. Frederik Simons say this could become a “runaway problem”, ultimately raising global sea levels by 6m or more.
About three million years ago so much of Antarctica melted that, according to some studies, all that extra water pushed the oceans about 17 metres higher. So understanding Antarctica and its smaller polar opposite in Greenland has gigantonourmously big implications for the future. Two studies last week looked at Antarctica and suggest the giant is probably already awake. The first study was further confirmation that the melting of the West Antarctic ice sheet is accelerating.
The world’s most powerful internal ocean waves were modeled in a new study published today in Nature by a research team that includes Sonya Legg, a Princeton senior research oceanographer in the Program in Atmospheric and Oceanic Sciences and a lecturer in geosciences.
Regarding the partial report on climate change due out on Friday, Roger Pielke, an environmental scientist at the University of Colorado in Boulder and Michael Oppenheimer, a Professor of Geosciences and International Affairs in the Woodrow Wilson School and the Department of Geosciences, both suggest that the Intergovernmental Panel on Climate Change (IPCC) might better spend its time doing more targeted reports, that take on specific defined issues, and release them more often.
