Cryosat-2 Now Sending Data on Arctic and Antarctic Ice Thickness

The Cryosat-2 mission is delivering on its promise to make high-precision radar measurements of polar ice.
The first data from the European spacecraft has been presented at an Earth observation meeting in Norway.
The information clearly shows Cryosat has the required sensitivity to assess the state of Antarctic and Arctic ice

Due to Melting Arctic, Colder Winters Will Be Rule Rather Than Exception

Last winter’s big snowfall and cold temperatures in the eastern United States and Europe were likely caused by the loss of Arctic sea ice. Arctic climatologist David Barber says that not only does the loss of ice affect conditions locally but “what happens in the Arctic dictates some of what happens in the mid-latitudes…This huge mass of warmer air over the Arctic in the late fall not only generates more wind and snow locally, several studies have now documented the impacts on global weather patterns.

Where in the World is the Worst Place for Cold Weather?

The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world.

Talks James Balog: Time-lapse proof of extreme ice loss

Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change.

Arctic at warmest levels in 2,000 years or more

Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates. The study, which incorporates geologic records and computer simulations, provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns.

More Evidence of Dangerous Climate Change: Ocean Surface Warming Breaks Record This July

The planet’s ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.

Satellite Shows Big Thinning of Winter Arctic Sea Ice, in Just Four Years

The volume of older crucial sea ice in the Arctic has shrunk by 57 percent from late 2004 to 2008. That is losing more volume of ice than water in Lake Michigan. Thin seasonal ice has replaced thick older ice as the dominant type for the first time on record.

Breakup of the tongue of Greenland’s Petermann glacier due within weeks

Arctic glacier poised to split up July 15, 2009 Sidney Morning Herald Environment  An ice island weighing many millions of tonnes is poised to break off the northern hemisphere’s largest glacier, say independent scientists travelling aboard a Greenpeace ship. Altogether, 5 billion tonnes of ice is set to crumble from the Petermann Glacier on Greenland’s [...]

In the Arctic, the “Climate Change Clock is Ticking”

What are not clearly understood are the impacts of feedbacks that will drive global warming faster and farther. Permafrost melting, for instance, will release vast amounts of methane, a powerful GHG, while the warming of the ocean will reduce its capacity to absorb GHGs.

The Arctic Ice Could Soon Be a Seasonal Feature

The Arctic Sea Ice, which has been a permanent feature for at least 100,000 years, is now so thin that almost all of it will disappear in about a decade. It will become seasonal, forming only during the winter.
