Aurora Australis from Space (Photo and Video of the Day)

For many of us, we’re never going to see an aurora. We simply live too far away from the poles. We might be able to make do with photos people have taken from the ground, but even that doesn’t match up with the video and image below, which show the aurora australis over Antarctica on September 11, 2005.

Weddell Sea Covered in Ice

Scientists working with NASA’s Operation IceBridge airborne research campaign started their third year of survey flights and captured this image of the sea ice covering the Weddell Sea.

Thawing Arctic Permafrost Likely to Release Large Amounts of Carbon

New research which contradicts 2007’s Intergovernmental Panel on Climate Change’s assessment suggests that billions of tons of carbon dioxide trapped in high-latitude permafrost may be released into the atmosphere by the end of this century if the temperatures continue to rise apace, which in turn will only further and quicken global warming.

Russian Arctic Ice Cover Nearing 2007 Record Low

A statement from the Russian environmental monitoring agency on Thursday says that the melting in the polar ice cap is nearing the 2007 record minimum levels, and in some instances is 50% smaller than the average.

Icy Ponds Mottle Arctic Ice {Photo of the Day}

Researchers on the NASA-funded ICESCAPE mission—Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment—have been examining melt ponds and the ice around them as seen in the image below.

West Antarctic Ice Sheet More Stable than Previously Thought

In many climate models and scientists’ theories the West Antarctic ice sheet is expected to melt over the coming hundreds of years and raise the sea levels. Much of this is based on the theory that during the last interglacial period the ice sheet must have melted in order to raise the sea levels as much as they had been. However new research suggests that the West Antarctic ice sheet may be more stable than had been previously realised.
