Scientists: Sea levels rising faster than expected
Published in Saudi Press Agency on 10 - 03 - 2009


The U.N.'s climate change
panel may be severely underestimating the sea-level rise caused
by global warming, climate scientists, calling
for swift cuts in greenhouse emissions, Reuters reported.
"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.
"The ice loss in Greenland shows an acceleration during the
last decade," said veteran Greenland researcher Konrad Steffen,
director of the Cooperative Institute for Research in
Environmental Sciences at the University of Colorado, Boulder.
"The upper range of sea-level rise by 2100 might be above
one metre or more on a global average, with large regional
differences depending where the source of ice loss occurs," he
said.
