Global warming may be causing ocean levels to rise twice as fast as previously expected, warns a climate physicist in Germany. Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research has used sea-level and temperature data spanning the twentieth century to create a very simple model for predicting ocean levels. Then, by using temperatures from future global-warming scenarios published by the Intergovernmental Panel on Climate Change (IPCC), he calculated that the sea level in 2100 will be 0.5-1.4 m higher than it was in 1990 (Science Express DOI: 10.1126/science.1135456).
