The big splash seems to be coming from Kristoff's reporting Al Gore's expectation that today's youth react in some way comparably to how us boomers would have:
"I can’t understand why there aren’t rings of young people blocking bulldozers,” Mr. Gore said, “and preventing them from constructing coal-fired power plants.”It's an interesting question, but I don't think it's Kristoff's biggest contribution. I think the concluding paragraphs are especially salient. This is where I'd like to direct your attention:
Critics scoff that the scientific debate is continuing, that the consequences are uncertain — and they’re right. There is natural variability and lots of uncertainty, especially about the magnitude and timing of climate change.
In the same way, terror experts aren’t sure about the magnitude and timing of Al Qaeda’s next strike. But it would be myopic to shrug that because there’s uncertainty about the risks, we shouldn’t act vigorously to confront them — yet that’s our national policy toward climate change, and it’s a disgrace.
