Huan Yi's quote was somewhat misleading as an overall representation of the article. The lead sentence of the article read, "For the first time in recorded history, the North Pole may be free of ice this summer, according to a published report Friday." I must agree with both Grinch and Balladeer that the quote they are discussing is not representative of that lead. They are correct to criticize, especially if the quote is complete and accurate.
The point of the article was, however, as I understand it, that the speed of the warming had been startling, not that the warming had happened at all, which the models had apparently predicted. The speed was the surprise. To environmentalists, who have been talking about this sort of thing since at least 1970, when I started following the whole sorry mess, this is not very much of a shock.
[Other environment predictions, such as the effects of population growth, have not come to pass, in part because they may have been partly wrong and in part because large parts of the world have tried to respond to the predictions in a sensible way. Also because new agricultural avenues have opened up which may or may not be of long term help. I include this here because I try to be fair as best I can. I put it in brackets because it seems a side discussion.]
Furthermore, it appears that the story that Huan Yi linked us to reports no particular connection between the fascinating vulcanism reported in Nature and the rise in oceanic temperature. I believe he would like to conclude that the rise in sea temperature was from local vulcanism and not from an unprecedented speed in a pattern of global warming due to emissions of green house gasses and use of fossil fuels and changes in oceanic ecology, among other preventable causal factors.
Since I am so clearly exercising an unwarranted level of mind reading here, I depend on the corrective powers of Huan Yi himself to set me straight on any incorrect attributions I have accidently laid at his feet. Sorry in advance.
