New Studies Shed Light on Past and Future Sea Level Rise

Sea levels worldwide will likely rise 50 to 130 centimeters by the end of the century if greenhouse gas emissions are not reduced rapidly, according to a new study led by the Potsdam Institute for Climate Impact Research. This study is the first to combine the two most important estimation methods for future sea level rise and therefore yields a more robust risk range. A second study provides the first global analysis of sea level data for the past 3,000 years, confirming that during the past millennia sea level has never risen nearly as fast as in the last century. These reports provide critical information for coastal planning.
