Holy sheet-a-roni, F6, that's exceptionally alarming. Even if they're off by a factor of 2, there's only 20 years left for the U.S. the E.U., China, Japan, and India (let's face it, they're among the few countries that can collectively make a meaningful difference in what may well be a trend that is unreversible) to halt this global catastrophe from occurring.
The ice sample evidence cited (I'm going to try to track down the study itself to further review it) appear to be both objective, compelling and catastrophic.
Given the glacial rate (no pun intended) it takes to effect a significant change in global politics and policies, this does not bode well.
After all, how long did it take to get the International Whaling Commission established and then, to adopt meaningful policies, monitoring and enforcement mechanisms. And, how long did it take Japan to figure out how to circumvent them? And the survival of whales is just a minor footnote when compared to the worldwide catastrophic effects of global warming.
God help our children. You can run, but you can't hide.
