Sea Level Rise Is Faster Than Predicted, Previous Estimates Of Rate Of Future Sea Level Rise Were Likely Too Low According To New Research

November 5, 2012 in Geology & Climate

Sea levels worldwide have been rising at a much faster rate than has been predicted by climate change models. The reasons for this are clear according to University of Colorado geologist Bill Hay; there are many large feedback loops that are just beginning to kick in, that will contribute significantly to future sea level rise.


The most recent official report from the IPCC was released back in 2007, and only predicted a global sea level rise of 0.2 to 0.5 meters by 2100. But current sea-level rise measurements are already meeting or exceeding the high end of that range, and have been suggesting a rise of at least one meter by 2100, possibly much more.

“What’s missing from the models used to forecast sea-level rise are critical feedbacks that speed everything up,” says Hay.
