Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder. The new study showed ice sheets like the Greenland Ice [...]

The largest chunk of ice in the Northern Hemisphere is on the move – at a four-hundredths-of-a-kilometer an hour clip. Satellite imagery from the European Space Agency shows that a massive iceberg that calved from Greenland’s Petermann Glacier on August 4 has cruised into the Nares Strait, putting 28 kilometers between it and its source. [...]

Scientists warn that temperature rise of between 2C and 7C would cause ice to melt, resulting in 23ft rise in sea level The entire ice mass of Greenland will disappear from the world map if temperatures rise by as little as 2C, with severe consequences for the rest of the world, a panel of scientists [...]

August 7th — A piece of ice four times the size of Manhattan island has broken away from an ice shelf in Greenland, according to scientists in the U.S. The 260 square-kilometer (100 square miles) ice island separated from the Petermann Glacier in northern Greenland early on Thursday, researchers based at the University of Delaware [...]

The Jakobshavn Isbrae glacier, one of the largest glaciers in Greenland, swiftly lost a 2.7-square mile chunk of ice between July 6 and 7, NASA announced late last week. The ice loss pushed the point where the glacier meets the ocean, known as the “calving front,” nearly one mile farther inland in a single day. [...]

Greenland is situated in the Atlantic Ocean to the northeast of Canada. It has stunning fjords on its rocky coast formed by moving glaciers, and a dense icecap up to 2 km thick that covers much of the island–pressing down the land beneath and lowering its elevation. Now, scientists at the University of Miami say [...]

From John Cook Sceptical Science I’m talking at the University of Queensland next week so I thought I might use Skeptical Science to test-drive a new visual metaphor. Sometimes in the climate debate, we get a bit lost in the data and statistical analysis, forgetting the sheer scale of the impact we’re having on our [...]

After little net change in the 1990s, Greenland is now melting and shedding billions of tons of ice, according to NASA satellite observations. This trend especially concerns scientists because meltwater and ice emptying into the ocean raise global sea level. Currently, sea level is increasing at about 1.25 inches per decade, and researchers estimate Greenland [...]

Study: Northwest areas thinning since 2005 Melt along the southern edge of Greenland’s ice sheet is now moving up its northwest coast, a new study shows. “The ice mass loss has been very dramatic” since 2005, John Wahr, study co-author and a University of Colorado at Boulder physics professor, said in a statement. The team, [...]

BALTIMORE — Microbes living under ice sheets in Antarctica and Greenland could be churning out large quantities of the greenhouse gas methane, a new study suggests. In recent years scientists have learned that liquid water lurks under much of Antarctica’s massive ice sheet, and so, they say, the potential microbial habitat in this watery world [...]
