Via the BBC: Arctic sea ice set to hit record low
Arctic sea ice looks set to hit a record low by the end of the month, according to satellite data.
Scientists at the US National Snow and Ice Data Center said data showed that the sea ice extent was tracking below the previous record low, set in 2007.

One of the positive feedbacks we were warned about twenty years ago.
And one of the great fears is that all melting, and the subsquent infusion of massive amounts of fresh water into the Atlantic, will affect the North Atlantic/Gulf Stream currents — and not in a good way.
And Greenland is getting darker, which will only make it’s melting problem worse.
Good thing climate change is a hoax and we don’t need to do anything about it.
The GOP flat-out rejects the science, while the Democrats are scared of mentioning it.
Can we get an Amen?
AMEN!

Actually it’s a proposed state-wide statute. To my knowledge it has yet to pass (or even come up for a vote):

I heard an interview with a corn farmer. He rejected global warming, and took the drought which killed his crop as natural variation. I found that sad.
(Bad weather is a gamble, a game of odds. Climate change does not make the weather in any given year or any given place a sure thing but it does load the dice. It makes extremes more likely.)

It’s a *possible* cause, but still not a conclusive one last time I checked. Right now the sample time is far too short to tell.
Trying to link climate change and weather is still a pretty tricky thing to talk about for a variety of reasons. Some of the linkages are tenuous at best. In other cases the measures we’ve used in the past may not work — i.e. my understanding is that the average intensity of hurricanes (measured traditional in terms of wind speed) has not greatly increased, nor necessarily have their sheer number, however the amount of average rainfall in hurricanes has as they appear to be taking on greater amounts of water due to a warmer climate.
The ‘northwest passage’ is now fairly regularly used for commercial shipping. Couldn’t find a link quickly but not too long ago saw an estimate of the tonnage carried through there in the summer of ’11 and it was surprising to me how large the number was. And of interest, the Canadian gov’t claims the passage as it’s ‘internal waterway’. Think what changes we’d be experiencing if there actually WAS anthropogenic global warming!
