Arctic Hothouse Turns UK, Europe, Eastern North America into an Icebox

It remains shockingly warm in much of the eastern Arctic (See my previous post that explains what is happening Arctic Hothouse Turns Europe into an Icebox )

Iqaluit one of the most northern communities in Canada is +2.1.C  (Jan 6) — a whopping 20C above normal as it has been for weeks. Normal night temps are -30C. This winter heat wave is creating havoc with rain instead of snow throughout much of the eastern Arctic.

Part of the reason is the heat stored in the Arctic ocean from this summer’s ice melt has delayed the annual freeze up. Here is the very latest satellite measurements which show the Arctic sea ice extent for December as the lowest on record.

This is affecting winter weather in many places such as Britain which had its coldest Dec in 100 years. And yes, climate change is a major player in all this.

Here’s a temperature map from mid December illustrating the super warm Arctic region and the icy cold Europe in the mid-latitudes. [[ see also temp anomaly chart showing Hudson Bay to Greenland is 18C above normal this week]]

And here is the Arctic sea ice extent – lowest ever for December.

As of Jan 2 Canada’s Hudson Bay is still not completely frozen over – likely the latest freeze up in a very long time. (10,000s of years?)

Last year’s cold and snowy winter directly connected to warmer Arctic new research reveals

By Stephen Leahy

OSLO, 15 June 2010 (IPS)

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, researchers concluded at the International Polar Year Oslo Science Conference in Norway in June.

Climate change has warmed the entire Arctic region, melting 2.5 million square kilometres of sea ice, and that, paradoxically, is producing colder and snowier winters for Europe, Asia and parts of North America.

“The exceptional cold and snowy winter of 2009-2010 in Europe, eastern Asia and eastern North America is connected to unique physical processes in the Arctic,” said James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States.

“In future, cold and snowy winters will be the rule rather than the exception” in these regions, Overland told IPS.

[[UPDATE Dec 29 2010 – Winter of 2010-11 appears to follow same pattern, see new post with northern hemisphere temp map for 20 Dec:  Arctic Hothouse Turns Europe into an Icebox]]

Scientists have been surprised by the rapid warming of the Arctic, where annual temperatures have increased two to three times faster than the global average. In one part of the Arctic, over the Barents and Karas Seas north of Scandinavia, average annual temperatures are now 10 degrees C higher than they were in 1990.

Overland explains the warming of the Arctic as the result of a combination of climate change, natural variability, loss of sea ice reflectivity, ocean heat storage and changing wind patterns, which has disrupted the stability of the Arctic climate system. In just 30 years, all that extra heat has shrunk the Arctic’s thick blanket of ice by 2.5 million square kilometres – an area equivalent to more than one quarter the size of the continental U.S.

The changes in the Arctic are now irreversible, he said. Continue reading →

Ice, Polar Bears & the Arctic Melt Down That’s Changing the World

The Arctic — The Earth’s Freezer — Is Defrosting With Dire Results

The rapidly warming Arctic region is destabilising Earth’s climate in ways science is just beginning to comprehend.

Arctic Ice Gone in 5 Years – First Time in One Million Years –– “We’re going to see huge changes in the Arctic ecosystem”

Things Happen Much Faster in the Arctic — “Things are happening much faster in the Arctic. I think it will be summer ice-free by 2015,” said David Barber, an Arctic climatologist at the University of Manitoba.

Arctic Is the Canary in the Coalmine — The Arctic is “ground zero” for climate change, with temperatures rising far faster than anywhere else on the planet.

Arctic Oil and Gas Rush Alarms Scientists — As greenhouse gas pollution destroys Arctic ecosystems, countries like Canada are spending millions not to halt the destruction but to exploit it.

Oh yeah, and about those polar bears:

Polar Bears Go Hungry as Icy Habitat Melts Away — The iconic animal of the frozen north, the polar bear, is starving to death because climate change is melting the Arctic Ocean sea ice.

Oil vs Polar Bears in Alaska — A coalition of environmental groups sued the George W. Bush administration Monday for delaying a decision to protect polar bears threatened with extinction

Polar Bears’ Future Bleak in Melting Arctic — “Without taking serious and urgent action to stabilize the climate, there is no future for polar bears” says Andrew Derocher, Chair of the World Conservation Union (IUCN), Polar Bear Specialist Group.

Climate Change: ‘Things Happen Much Faster in the Arctic’ – Summer Sea Ice Could be Gone Soon

“We’re going to see huge changes in the Arctic ecosystem“

QUEBEC CITY, Canada, Dec 13 2008 (IPS)

In just a few summers from now, the Arctic Ocean will lose its protective cover of ice for the first time in a million years, according to some experts attending the International Arctic Change conference here.

A summer ice-free Arctic wasn’t due for another 50 to 70 years under the worst-case climate change scenarios examined by the Intergovernmental Panel on Climate Change (IPCC).

“Things are happening much faster in the Arctic. I think it will be summer ice-free by 2015,” said David Barber, an Arctic climatologist at the University of Manitoba.

Such a “dramatic and serious loss of sea ice will affect everyone on the planet,” Barber told IPS. Continue reading →
