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.
The 245-square-kilometer [...]

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 told [...]

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 said.
The [...]

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. [...]

When scientists say the planet is warming, they usually point to rising air temperatures as proof. That’s reasonable enough, especially since the warmth of the air temperature affects us directly so we feel the change the scientists are measuring. But it’s also misleading: while the lower atmosphere has been gradually warming over the past 50 [...]

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 [...]

EVERYONE knows how much hotter it feels to wear a black T-shirt, rather than a white one, on a warm day.
In the same way, the melting of sea ice in the Arctic, revealing the dark water below, has been shown by Australian scientists to be the main cause of unusually rapid warming at the top [...]

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 climate. [...]

New sediment cores from an Antarctic research drilling program suggest that the southernmost continent has had a more dynamic history than previously suspected
ERICE, Italy—If you think of Earth’s poles as fraternal twins, the Arctic has been the wild one in recent years, while the Antarctic has been a steady plodder. Withered by summer heat, Arctic [...]

In another display of the sea change that has occurred at the US Environmental Protection Agency under the current administration, a new report was issued yesterday regarding indicators of climate change. The report, entitled “Climate Change Indicators in the United States,” measures 24 separate indicators showing how climate change affects the health and environment of [...]
