Sea levels rising faster than expected – scientists

COPENHAGEN, (Reuters) – The U.N.’s climate change  panel may be severely underestimating the sea-level rise caused  by global warming, climate scientists said on Monday, calling  for swift cuts in greenhouse emissions.

“The sea-level rise may well exceed one metre (3.28 feet) by  2100 if we continue on our path of increasing emissions,” said  Stefan Rahmstorf, professor at the Potsdam Institute for Climate  Impact Research. “Even for a low emission scenario, the best  estimate is about one metre.”

Rahmstorf spoke at the International Scientific Congress on  Climate Change in Copenhagen.    The U.N.’s Intergovernmental Panel on Climate Change in 2007  predicted global warming would cause sea levels to rise by  between 18 cm and 59 cm (7 inches and 23 inches) this century.    The IPCC said at the time the estimate could not accurately  take into account factors such as the melting of ice sheets in  Greenland and Antarctica. Many scientists criticised the number  as too conservative.
