The sea ice minimum in the 1970s was 5.5 million square kilometers. Then in the 1980s it was 5.0 million square kilometers. Then in the 1990s it reached 4.5 million square kilometers. Then by 2005 we touched 4.01 million square kilometers as the prior record.

Then comes 2007. Oh my, does 2007 come roaring by! On August 9, 2007 we set a new record low of 3.98 million square kilometers! But just 19 days later we set a new minimum of 2.99 million square kilometers.
Did you get that yet? We lost one million square kilometers of sea ice in 19 days.

The more ice free sea there is , the more heat is absorbed - which leads to more ice melting and more ice free sea, and so on. It's a "positive feedback loop", the melting is not linear.
I don't know if global warming is all our fault but I think this is significant news.

I did not post do dispute global warming, I cannot say what causes it. I just posted about the massive melting of the ice - it's not something you see every day, I do not care the reason

If floating ice melts ,the sea level does not rise. Only if land ice melts the sea level rises. Just a 1 meter rise is enough to cause problems for Bangladesh.
Greenland and the Antarctic peninsula are the areas that could melt, each would add 6 meters to the sea level.
But with ice melting at the North Pole the Gulf Stream could stop and a new ice age could begin before serious melting occurs
What I think : the ice free sea will heat up and the gulf stream stopping will not cause an ice age. The Gulf Stream heats the northern Europe, but if the North Pole will be free of ice, it will be heating up by itself

The ice cap over the Arctic Ocean is melting, due partially to our use of fossil fuels. The melt has revealed a new potential oil area. The result? An international land grab as countries with Arctic borders vie to become the world's next big oil producer.

You know what I think is at the heart of this debate but is unspoken. Do we really CARE? I mean would it really be such a terrible thing to wipe people off the face of the earth and maybe a couple hundred survive and have to start over again? Would it really be a bad thing?

The Arctic may be loosing Ice, but the Antarctic is gaining it. The Polar Bears are going to have to move south.

Yeah, well he says a lot of things. He's probably programmed by Disney to do so.

Greenland is actually gaining ice as well.

Well, yeah if my children and grandchildren are not in that couple of hundred that survive. That would be a bad thing, to me anyway.

Maybe someone should tell them to start swimming now.

Oooh - this means the fabled "North West Passage" (e.g. a link between the Atlantic and Pacific oceans via the North Pole) might be open (again ? ). That could have quite an impact on international commerce.

question: the Victorians where MAD about the idea of the North West Passage. Was it pure speculation, or where they picking up on earlier legends of a passage ? (e.g. the North Pole had melted previously, and recently enough to have been incorporated into myth and legend ? )

Who can tell.

Not me... I'm a badly drawn Cat. I don't to Cold Weather exploration grin2.gif

I agree. Let the Earth exact it's revenge. Humans don't want to learn any lessons anyway. It's consume, consume, consume, and history has yet to teach us any lessons.

The Northwest Passage is one of the most fabled sea routes in the world - a short cut from Europe to Asia through the high Arctic.

Recent years have seen a marked shrinkage in its ice cover, but this year it was extreme, Esa says.

It says this made the passage "fully navigable" for the first time since monitoring began in 1978.
