The National Oceanic and Atmospheric Administration has released its 2011 Arctic Report Card. Persistent warming has caused dramatic changes in the Arctic Ocean and the ecosystem it supports. Ocean changes include reduced sea ice and freshening of the upper ocean, and impacts such as increased biological productivity at the base of the food chain and loss of habit for walrus and polar bears.

Arctic Melt update: Scientists now have unambiguous evidence that the theorized phenomenon known as "polar amplification" has in fact been occurring for the past 5 years. It was not expected to be seen for at least another 10 or 15 years. "We're in a vicious positive feedback loop." [more inside]

Dispatches from Polar Scientists -- A compilation of blogs "in celebration of the International Polar Year (2007-08), [giving] you an up-close-and-personal look at research in extreme environments through the thoughts and experiences of the scientists working there. We’ll post their photos, videos, and blogs on this site."

"We badly underestimated the degree of damages and the risks of climate change," said Lord Stern in a speech in London yesterday. "All of the links in the chain are on average worse than we thought (pdf) a couple of years ago." [more inside]

New Jersey is drowning , or rather it would if the the future as predicted by David Spratty & Philip Sutton in climate code red comes true. Philip Sutton said in an interview that "within five years the Arctic ice in the summertime will be all gone.". With all the ice melting, the waterlevels rise - will your house be under water?

Video (8MB, MPEG) of arctic sea ice extent, recorded from January to September 2007. [other formats] This summer a dramatic decrease compared to previous years in the extent of the north pole ice cap was observed. Scientists are freaked out [bugmenot]. This summer, the Northwest Passage was open for a few weeks, allowing three ships to traverse it. [more inside]

"In an average August between 1979 and 2000, the Arctic Ocean was covered with about 3 million square miles of sea ice, according to the National Snow and Ice Data Center. By Labor Day this year, the total had shrunk to a little more than half that, shattering the previous record low set in 2005."

With global warming trends melting permafrost throughout the arctic circle, we may be seeing more and more of this phenomenon: Drunken Forests. An artist responds.

An Educational Exploration of Nunavut. "Setting out to document arctic climate change we will dogsled the territory of Nunavut, meeting Inuit Elders and students, to explore traditional ecological knowledge in the remote communities visited along the trail while gathering scientific data daily from the field for NASA and Environment Canada." - a cool expedition to bring some attention to what many are describing as the greatest threat to mankind today.

another canary tips over
as the administration (more specifically the white house council on environmental quality and its head james l. connaughton) continue to ignore and bury the warnings of the effects global warming from their own scientists.

The warm water ocean currents of the Gulf Stream are why London rarely gets snow yet Boston is fridged despite London being as far north as Montreal, Canada. New weather modeling research from Columbia University may turn this long-held belief on its head; London can thank the Rocky Mountains for its mild winters. Good news for the rest of Europe too in case the Gulf Stream stops due to Arctic melting.

Artic Ice Cap is now perfect for slushballs and snowmen
Once the North Pole was covered in that kind of hard, dry, icy snow that you couldn't pack. Now sping is here! Robin red-breast and the Easter Bunny can't be far behind. Let's pelt each other with snowballs and build a fort before it all melts away, and the long summer of human-made Armageddon melts us all. What a world, what a world. Not that we haven't seen it coming.
