I used to post more about global warming/climate change in the earlier days of Attytood (yes, it's been around so long that there are now "earlier days.") The issue never went away -- in fact the crisis has grown more dire, as highlighted this time last year when carbon dioxide passed the no-turning-back 400 ppm threshold. But writing about it seemed like a zero-sum game -- the near unanimity of the world's climatologists on the reality of man-made global warming never changed or wavered, nor did the reaction of blog commenters who cite whatever the latest ExxonMobil- or Koch-Brothers-sponsored research is (as you'll surely read tonight, in the comments below.)
But sometimes, it's necessary to remind people, and this seems to be one of those times:
The collapse of large parts of the ice sheet in West Antarctica appears to have begun and is almost certainly unstoppable, with global warming accelerating the pace of the disintegration, two groups of scientists reported Monday.
The finding, which had been feared by some scientists for decades, means that a rise in global sea level of at least 10 feet may now be inevitable. The rise may continue to be relatively slow for at least the next century or so, the scientists said, but sometime after that it will probably speed up so sharply as to become a crisis.
