Looking at the Jakobshavn Glacier in Greenland from the NASA Research Aircraft. As scientists continue to warn of melting glaciers in Antarctica, a key glacier in Greenland is growing again, NASA says. for the past 20 years, have grown and are running slower, researchers from NASA's Jet Propulsion Laboratory say.

Although the glacier is still losing more ice for warmer ocean water than it gains from snow accumulation, researchers note Jakobshavn showed signs of progressing rather than retreating.

"We did not believe at first," says Ala Hazander, lead author of the study, working at NASA's Jet Propulsion Laboratory. "We have just assumed that Jakobshavn will just go on as it has been for the past 20 years."

The study was published on Monday in the reviewed journal Nature Geoscience. is caused by a climate model that drives the North Atlantic to swirl between the cooler and warmer waters every five to twenty years. Researchers found water near the glacier, which was colder than the eighties of the last century. 19659005] Josh Willis, OMG mission chief investigator, said that this cooling model is just a "pause" for the glacier and will probably retreat as the climate reheats the water. "In the long run, the oceans are warm and when the oceans have so much influence on the glaciers, that's bad news for Greenland's ice sheet."

Earlier this year, researchers have warned that Greenland is approaching a critical point for melting the ice. In January, a study published in the reviewed journal of Practice of the National Academy of Sciences found ice in Greenland melting four times faster than it was 16 years ago.
