Intuitively, I would expect a trend towards small 'clumps' of ice scattered over a wider area to be an indicator that polar ice is not freezing as well as it has in the past.
In short, we are seeing a slushy forming, not an ice cube.
Albedo effect
The Arctic is warming up three times more quickly than the rest of the Earth, in part because of the reflectivity, or the albedo feedback effect, of ice.
As more and more ice melts, larger expanses of darker sea water are exposed. These absorb more sunlight than the ice and cause the water to heat up more quickly, thereby melting more ice.
Barber says the ice is now being melted both by rays from the sun as well as from below by the warmer water.
Scientists are also seeing more cyclones, which pick up force as they absorb heat from the warmer water. The cyclones help generate waves that break up ice sheets and also dump large amounts of snow, which has an insulating effect and prevents the ice sheets from thickening.
After a long search, Barber's ice breaker finally found a 16 kilometre wide floe of multiyear ice that was around six to eight metres thick. But as the crew watched, the floe was hit by a series of waves, and disintegrated in five minutes.
"The Arctic is an early indicator of what we can expect at the global scale as we move through the next few decades ... So we should be paying attention to this very carefully," Barber says.

Honestly, they should just change their title to Global Climate Destabilization (is GCD really so hard?) to make themselves more relevant.
oh, and whoever said "This jackass almost became our president" or whatever:
You liked W Bush and his dishonest way of winning an election? LOLOLOLOLZZZZZZZZZ
From my perspective: There's a chance that Gore may be sensationalizing this data but on the other hand, they recently had a great deal of trouble with those e-mails being taken out of context. I want to think that they wouldn't do something as stupid as outwardly lie after a fiasco that has people who know nothing about the weather saying "case closed".
goddamn glenn beck
Please tell me how you have come to the conclusion that the emails were taken out of context? Any links? Did you actually look at the emails??

such dogmatic positioning does not aide understanding and reason

true, this is closer to being an opinion because it hasn't been officially proven. However, do you really think we can just keep being as wasteful and inefficient as we are and absolutely nothing is going to happen?

I hate Al Gore saying the debate is over as much as I hate Glenn Beck for saying the debate is over (among other things)
I kind of just see it like this:
people=totally F%*#)% stupid
Telling them that there is no global warming leads to things like, complete disregard for dumping and littering.
extreme example but somehow, TOTALLY feasible.
Rubbish.
The latest 2 (and only the latest) were the roman warm period, and the medievil warm period.
Both of which were warmer than now.

Rubbish squared.
Both these events were LOCAL, REGIONAL events, NOT GLOBAL. The current discussion is about GLOBAL events.
Excellent discussion here about the MWP.

I am talking on behalf of the UK and I am pretty sure these are steps towards the one world Government. The message certainly is not hidden, it's a slap in the face if people really look behind the scenes and think.
"While that may seem to contradict the idea of global warming, it has long been known that carbon dioxide causes warming in the lowest part of the atmosphere and cooling in the upper layers of the atmosphere"
And rubbish cubed, because as we have seen, some parts of the globe cool, while other parts of the globe allegedly warm, which is why they changed the name from "Global Warming" to "Climate Change"
For global warming to occur, the whole globe has to warm, and that just hasn't been the case.
The AGW proponents will try and use an average rise to convince us, but that doesn't work either.
In fact the average rise was greater during both the MWP and RWP.
Please try and do some research and make sure of your facts.
