Following on from our last report, the rapid disappearance of the Arctic's ice cover finally seems to have ceased. The NSIDC reports that, based on the 5 day moving average that they use, the minimum ice coverage occured about the 16th September. (Note that they do point out that at this time of year it is still possible for some additional ice loss to occur.)
On this date the ice extent coverage was 4.13 million square kilometers (1.59 million square miles) which appears to be the 2007 minimum. The five-day 2005 minimum (the previous record low) was 5.32 million square kilometers (2.05 million square miles) in 2005, which has been shattered by 1.19 million square kilometers (460,000 square miles). That's an area of ice less than before that is roughly the size of Texas and California combined, or nearly five United Kingdoms.
On top of that, the fabled North West passage has been largely navigable for just over 5 weeks, something that has not occurred in recorded human history. Even the North-East passage has only been blocked by a few kilometres of ice this year.
Whichever side of the climate change debate you fall on (man-made, natural or man enhanced natural), the evidence that the planet is warming significantly and rapidly is now almost unarguable.
What on earth will the next few decades bring about for the Arctic? The Costa Del Greenland perhaps?

I believe in freedom of speech. But I also don't like bullies on blogs, even verbal ones, as they can drive away those with something valid to say... or offer.
Subjective is fine, but well argued and substantiated is even better. Calm and polite tops. Anything that crosses my personal line will not go up. There may be reasons given, but not guaranteed.
I'm not too keen on 'Anon' as a handle (and the content usually explains why), so if that's what you opt for it may not make it. Sorry.
