Sea levels could rise 1.3 to 2 metres by 2100

摘要

New studies have been published concluding that sea levels could rise far more rapidly than expected in coming decades. The UN's climate science body had predicted up to a metre of sea level rise this century. But a new study led by the Potsdam Institute for Climate Impact Research for the first time, combines the two most important estimation methods for future sea level rise and yields a more robust risk range. Sea levels worldwide will likely rise by 50 to 130 centimetres by the end of this century if greenhouse gas emissions are not reduced rapidly. A second study provides the first global analysis of sea level data for the past 3,000 years. It confirms that during the past millennia the sea level has never risen nearly as fast as during the last century. Even if ambitious climate policy follows the 2015 Paris Agreement, sea levels are projected to increase by 20 to 60 centimetres by 2100.
