Antarctic Melt May Double Sea-Level Rise

According to new research published Thursday in the journal Nature, ice melting from Antarctica could cause a dangerous rise of as much as 6 feet in global sea levels by 2100, nearly double the amount scientists had projected if carbon emissions continue to rise unchecked. The additional source of sea-level rise adds to previous estimates of sea level rise normally calculated based on Greenland ice melt and glaciers located elsewhere. A scenario where civilization obtains net-zero or negative carbon emissions by 2100 would stem the rising sea, the study contends.
