Just seen on the "ill considered" blog: NSIDC and NASA have announced that the Arctic sea ice has reached its minimum extent for this year, which is the second lowest after last year's record. The announcement may be a bit early but probably it's ok. Anyway the conclusion was already clear for a while: The rapidly declining trend is confirmed.
In my opinion (though I am not really an expert on this), the decline of the Arctic sea ice is not only a visible sign of climate change but possibly the most important example of an amplifying feedback that is kicking in and may be impossible to reverse. So it's worthwile to follow the development.

I think the only way out of this would be a fairly big vertical volcanic eruption in the northern hemisphere. The cure is often as bad or maybe worse than the problem
