guys,
I read a recent article somewhere on net that stated thus "Possibility of an Ice Free Arctic this summer is very high"...
How plausible this scenario is?

The article was in The Independent. I suppose the plausibility would depend on what you define as the Arctic. The article meant the North Pole, I think, and said it was extremely plausible.

Good to see your answer.... but there are conflicting views stating that the melting of sea ice may not result in considerable increase in the sea level...it surely will reduce the earth's albedo effect...but any idea about its probability of causing a catastrophe.....

It's pretty plausible - Someone made the north west passage in a fishing trawler in about 2 weeks a couple of years back.
The Canadians are pretty twitchy about it because sooner or later people are going to start using it as a shipping route and then it's just a matter of time before they get calls from cargo ships and oil tankers who've left it a bit late and get caught in the winter ice

thats a nice answer jake-the-peg...people are pretty oppurtunistic in this regard as opening of north west passage seems a blessing in disguise for those cargo ships that would otherwise go around the Panama Canal.....

never heard about him...what prompt you to ask me this question suddenly and what resemblence does it have to our current thread on Global Warming

The article you read most likely said that the ice cover had shrunk to its lowest level since the first satellite images were observed.
Reports like this tend to be seized upon and broadcast loud and wide by the global warming brigade
What the article probably didn't mention was that the ice grew back last winter at its fastest rate ever recorded, and that there are presently 700,000 more square kilometers of ice today than there were at this time last year.
This is the sort of additional report that the global warming brigade don't want you to hear about.

This is typical Global Warming Skeptic behaviour.
No sources, take something out of context and hint to a concept of some sort of liberal conspiracy.
L:ets leave it with the US National Snow and Ice Data Center shall we:
http://nsidc.org/arcticseaicenews/index.html
Arctic sea ice has declined dramatically over at least the past thirty years, with the most extreme decline seen in the summer melt season...
Arctic sea ice extent for June 2008 is close to that for 2007, which went on to reach the lowest minimum since at least 1979. More notably, however, satellite data indicate that melt began significantly earlier than last year over most of the Arctic Ocean

Hi Jake. One of the problems on AB is keeping answers short, and avoiding rambling on..
There is a website that specialises in detailing polar ice cover, and has no axe to grind, here.
If you click on the first graphic thumbnail, you'll see the source for my previous answer.

Again we need to understand whether that article tells us about Arctic Sea ice or Land ice as both exhibit different behaviour.....is it not heathfield?

And if you click on this link
http://arctic.atmos.uiuc.edu/cryosphere/sea.ic e.minimum.2007.html
On the very same site
you'll see that same graph (which is over a year) below a much more revealing one that shows how the summer minimum has been declining over the last 30 years.
None of this of course tells us anything about the human contribution.
But there are very few people around these days who seriously argue that there is no climate change going on at all - it gets hard to explain where all the glaciers are going, and why there's less polar ice each summer

Not plausible. Not a wind up as such, but taking a few liberties with eco warming and people's worry levels.

Ridiculously implausible, as I would have answered last January, when ye posted yer Question. It is now mid-August.
No shortage of Ice yet!
