Will New York be the new Venice? A study in the journal Nature Geoscience suggests that global warming might cause sea levels to rise twice as fast as predicted by the International Panel on Climate Change.
By looking back at the last time in the geological record that temperatures warmed as quickly as they're doing right now, the researchers determined that we may be wildly underestimating the rate at which the oceans may rise. Their study suggests that the actual rise in sea level by the end of the 21st century could be around 64 inches, double the IPCC estimate of 32 inches. The end result could be catastrophic for low-lying areas, which would become much more vulnerable to flooding and storm surges.
The report comes follows recent news that sea ice in the Arctic is melting far more rapidly than expected. While that doesn't directly contribute to a rise in sea levels, the loss of sunlight-reflective ice is believed to create a feedback loop which accelerates global warming.
