Massive Greenland meltdown? Not so fast, say scientists

Massive Greenland meltdown? Not so fast, say scientists

No sunbathing on the beaches of Greenland in our lifetime?

A general view shows the Arctic Ocean off the coast of Greenland. The recent acceleration of glacier melt-off in Greenland, which some scientists fear could dramatically raise sea levels, may only be a temporary phenomenon, according to a study published Sunday.
The stakes are enormous: the rate at which the global ocean water mark rises could have a devastating impact on hundreds of millions of people living in low-lying areas around the world.
But a team led by Faezeh Nick of Durham University in Britain found that neither of these scenarios matched the data.
"They simply don't fit what we have observed," said colleague and co-author Andreas Vieli in an interview.

Arctic sea ice reflects sunlight, keeping the polar regions cool and moderating global climate. According to scientific measurements, Arctic sea ice has declined dramatically over at least the past thirty years, with the most extreme decline seen in the summer melt season.
