In its 2007 report, the U.N. Intergovernmental Panel on Climate Change projected seas would rise 7 to 23 inches by 2100. But that estimate carried a strong caveat: The science panel warned that an additional rise could come from the rapid and unpredictable melting in Greenland and Antarctica, which it didn't attempt to estimate.
Many scientists now believe seas will rise close to 1 meter, or 3.2 feet, by the end of the century, but their estimates still carry a sizable margin of error.
The data from the new study has been submitted to the IPCC for inclusion in the panel's next major report, which is due in late 2013.
