New Study Lowers Estimate of Ancient Sea-level Rise
March 14, 2012
The seas are creeping higher as the planet warms. But how high will they go? In Bermuda and the Bahamas, researchers have gone looking for answers. By pinpointing where shorelines stood during a warm period 400,000 years ago, they hope to narrow the range of projections. After correcting for apparent sinking of the islands, the researchers, who've published their study in Nature, estimate the seas rose 20 to 43 feet higher than today--far less than previous estimates.
