Arctic Sea Ice is Cracking Under the Strain
I'm currently engaged in a debate on Twitter with @Cornishview. His avatar doesn't reveal a gender, so I'm guessing here, but it does suggest that he understands the part that coal and the latent heat of vaporisation of water played in the beginning of the industrial revolution down here in not so sunny South West England. Cornishview says over on Twitter that:
I prefer to look at facts not idealism. Fact – No link between CO2 & Climate change. Fact – Renewable energy causing Fuel Poverty.
Personally I strongly disagree with the first of those so called "facts". Here's a bit more evidence for my side of the argument. Regular readers may recall that at the end of last November the temperature in the North East of Greenland was twenty degrees Celsius above "average". As I pointed out to a somewhat sceptical commenter on that story, if that doesn't count as at least "local warming" what on Earth does?
This morning, over on the Pacific side of the Arctic for a change, comes further evidence. This is what the situation looks like from space, courtesy of an Advanced Very High Resolution Radiometer (or AVHRR for short):
As you can plainly see, if you have eyes to so do, whatever little that's left in the way of sea ice covering the Beaufort Sea north of Alaska and Canada is currently cracking at the seams. According to an expert in such matters on the Arctic Sea Ice Blog:
The mid-February breakup we're observing in the Bering and Beaufort appears to be very unusual, possibly unprecedented in recent millenia, for this time of year. In the spring of 2012, something rather similar happened but in April.
"A-Team" also kindly provided a "video" of what happened in April 2012 in the same vicinity. Here it is:
According to A-Team once again:
If taken as a simplistic predictor of the 2013 melt season, we are 51 days ahead of last season.
I'm off to Twitter now, to tell @Cornishview the good news.
