BERLIN -- Sea levels could rise by 2.3 metres for each degree Celsius that global temperatures increase and they will remain high for centuries to come, according to a new study by the leading climate research institute, released on Monday."
"Anders Levermann said his study for the Potsdam Institute for Climate Impact Research was the first to examine evidence from climate history and combine it with computer simulations of contributing factors to long-term sea-level increases: thermal expansion of oceans, the melting of mountain glaciers and the melting of the Greenland and Antarctic ice sheets.
Scientists say global warming is responsible for the melting ice. A U.N. panel of scientists, the IPCC, says heat-trapping gases from burning fossil fuels are nudging up temperatures. A small number of scientists dismiss human-influenced global warming, arguing natural climate fluctuations are responsible."
