Melting Arctic Sea Ice Causing Cold, Snowy Winters

SustainableBusiness.com News

While it may be tempting to conclude the biting cold and endless snow characterizing this winter in the Northern US and Europe is just a random weather event, scientists say it's a result of very rapid climate change.

The warming and melting of the Arctic is happening much faster than expected. Some experts expect the summer Arctic ice cover to be essentially gone in as little as five years. Just a few years ago, no one thought a summer ice-free Arctic could happen before 2060.

Arctic temperatures have been 21 degrees C above normal for over a month. New data reveals that huge volumes of warmer water from the North Atlantic are flowing into and warming the Arctic Ocean, researchers reported in the journal Science.

"Boats were still in the water during the first week of January," said David Phillips, a senior climatologist with Environment Canada, referring to southern Baffin Island, some 2,000 km north of Montreal. This is a region that receives just four or five hours of weak sunlight during the long winter. Temperatures normally range from -25 to -35 degrees C but were above zero on some days in January.

An international team of researchers analysed marine sediments and found that temperatures of the northward inflowing Atlantic water varied by just a few tenths of a degree Celsius during the past 2,000 years. However, in the last hundred years temperatures have shot up by two degrees C.

The Arctic and Antarctic regions are key drivers of Earth's climate. The snow and cold in the eastern US and Europe during last year's winter is being repeated this year - likely the result of the loss of Arctic sea ice.

Over 90% of excess heat trapped in the atmosphere from burning fossil fuels is going into the oceans.

As more and more sea ice melts, there is more open water to absorb the summer sun's heat. A day of 24-hour summer sun in the Arctic puts more heat on the surface of the ocean than a day in the tropics, James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States told Inter Press Service .

That extra heat in the ocean is gradually released into the lower atmosphere from October to January as the region slowly re-freezes months later than normal. This is a fundamental change - a large part of the Arctic Ocean is radiating heat instead of being cold and ice-covered. That has disrupted wind circulation patterns in the northern hemisphere, reported Overland and other researchers at the International Polar Year Oslo Science Conference in Norway last June.

The result: the Arctic stays warm and mid-latitude regions become colder and receive more snow for much of the winter. Last December was the coldest south Florida has experienced in more than a century of record-keeping.

Most of Britain suffered through its coldest December ever. Up in the Arctic, Coral Harbour on the northwest corner of Hudson Bay was above zero degrees C for two days in early January for the first time in history. Much of the eastern Arctic centred around Baffin Island averaged +21C above normal between Dec. 17 and Jan. 15 this year.

This looks to be the new normal since Arctic experts agree the melting sea ice is now locked into a death spiral.

"In future, cold and snowy winters will be the rule rather than the exception" in the eastern United States and Europe, Overland previously told IPS.

This week the U.S. northeast suffered through its sixth major snowstorm this winter, breaking all snowfall records.

I have prime real estate in Tokyo for sale too - real cheap.. Look at the history of these lunatics. It's this, it's that, no no we were wrong it was this, it was that.. Follow the money - the new Green Investments by large firms is what is driving this hogwash.

What a crock of BS. It colder because it is warmer. Why are people so determined to keep promoting the lie. Money, yes Money. How do these "scientists" get grants if there is no problem? So they fake the data and conclusions. Pitiful

The effects described in the article have long been predicted--for the past twenty years at least. When predictions generated by modeling are borne out by actual events, that is not BS--that is science at work. If it's all BS your cell phone would be a Dick Tracy toy, not an essential part of your life. The scientific method, with its cycle of hypothesis, experimentation, results, and further questioning has given us the comfortable, convenient life we very much enjoy. To mock it is to mock the foundations of modern American prosperity and society.

So, why aren't we building nuclear power plants and hydro power plants as fast as humanly possible - http://www.euronuclear.org/1-expert/hsc-position-papers.htm and taxing the bejesus out of gas guzzlers?

Ice is was off this year in Baffin Island, was late to form in Hudson Bay and the Gulf of St. Lawerence is not fozen on 2-16-11 and normally is. On the other hand Ice in the Bering Sea is up, the Barrents Sea is normal and was down last year, and the Arctic above Siberia froze close to normal The Antarctic Sea Ice has been above normal for years and is growing. Of course there is barely any data before 1979 when the first satelite went up. I wish we would hear about all the data. http://nsidc.org/data/seaice_index/images/daily_images/N_daily_extent_hires.png

Colder because it's warmer...seriously. Is there anything that can happen that these people can't link in some ridiculous way to global warming? Man I have never seen so many people willing to "go down with the ship" on a theory like this. Is it money, brainwashing, people needing something to cling to, lack of any other thing scary enough to get people to stop polluting?
