Greenland's glaciers are losing ice - but not at the breakneck pace that scientists once feared, a new study says.

The loss of ice from the glaciers that cover the island is still about 30% faster than it was a decade ago, researchers said.

That means Greenland's contribution to future sea level rise would be about four inches by the year 2100 if ice loss does not speed up much more, a study author said.

That may not sound like much, but when other causes of sea rise around the globe are added, the total could still be about three feet by the end of the century, researchers said.

‘'Glacial pace' is not slow anymore,’ said study author Twila Moon, a glacier researcher at the University of Washington. Read More
