The Warming of Greenland

By JOHN COLLINS RUDOLF
New York Times

LIVERPOOL LAND, Greenland — Flying over snow-capped peaks and into a thick fog, the helicopter set down on a barren strip of rocks between two glaciers. A dozen bags of supplies, a rifle and a can of cooking gas were tossed out onto the cold ground. Then, with engines whining, the helicopter lifted off, snow and fog swirling in the rotor wash.

When it had disappeared over the horizon, no sound remained but the howling of the Arctic wind.

“It feels a little like the days of the old explorers, doesn’t it?” Dennis Schmitt said.

Mr. Schmitt, a 60-year-old explorer from Berkeley, Calif., had just landed on a newly revealed island 400 miles north of the Arctic Circle in eastern Greenland. It was a moment of triumph: he had discovered the island on an ocean voyage in September 2005. Now, a year later, he and a small expedition team had returned to spend a week climbing peaks, crossing treacherous glaciers and documenting animal and plant life.

Despite its remote location, the island would almost certainly have been discovered, named and mapped almost a century ago when explorers like Jean-Baptiste Charcot and Philippe, Duke of Orléans, charted these coastlines. Would have been discovered had it not been bound to the coast by glacial ice.
...
The sudden appearance of the islands is a symptom of an ice sheet going into retreat, scientists say. Greenland is covered by 630,000 cubic miles of ice, enough water to raise global sea levels by 23 feet.

Carl Egede Boggild, a professor of snow-and-ice physics at the University Center of Svalbard, said Greenland could be losing more than 80 cubic miles of ice per year.
