Burp.

A new article in Nature warns that "the costs of a melting Arctic will be huge", thanks in part to the likely release of "a 50-gigatonne (Gt) reservoir of methane, stored in the form of hydrates" beneath the East Siberian Arctic Shelf, "either steadily over 50 years or suddenly". An abrupt release is "highly possible at any time", says Natalia Shakhova of the University of Alaska at Fairbanks, who has observed plumes of methane up to a kilometre wide bubbling to the surface in the area.

"all gone by 2015"

While the 2007 IPCC report showed Arctic sea-ice still present in 2100, it is now an unfolding "global disaster" according to Cambridge Professor Peter Wadhams. Climate Code Red summarizes the science, saying the sea-ice is "in a 'death spiral' and likely to be gone in summer within a few years" ... "The sea-ice volume is now down to just one-fifth of what it was in 1979", and paints a newly emerging, rapidly worsening climate picture, urging climate scientists to sound the alarm on new data showing a world on the brink of dramatic tipping points, far sooner than anyone anticipated

Summer ice in the Arctic to disappear

Several measures of Arctic ice cover have hit record lows. Melting usually continues into September, so this year’s minimum should be below the 2007 record. The rate of melting far exceeds that predicted by most models. Predictions of when the Arctic might be entirely ice-free at the summer minimum are being brought sharply forwards.

The Arctic is failing.

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 icemelt unambiguous evidence

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]

Blogging from the top of the world

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."

Impermafrost

"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]

Bye Hoboken, as you drown in climate-changed caused floods

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?

September 2007 polar sea ice anomaly

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]

The Polar Slush Cap?

"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."

That forest is such a lush...

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.

polar husky

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

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.

gulf stream

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

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.
