Greenland ice melt may cause dramatic change of northeast coasts

by Candace Lombardi
A new study from the National Center for Atmospheric Research (NCAR) has found that Greenland's melting ice may have a greater effect on sea level rise on the northeastern coasts of the U.S. and Canada than previously hypothesized.
"If Greenland's ice melts at moderate to high rates, ocean circulation by 2100 may shift and cause sea levels off the northeast coast of North America to rise by about 12 to 20 inches (about 30 to 50 centimeters) more than in other coastal areas. The research builds on recent reports that have found that sea level rise associated with global warming could adversely affect North America, and its findings suggest that the situation is more threatening than previously believed," NCAR said in its preliminary report.
