So instead, I'm going to take you to Peter Watts and he shall set you straight.
I will add two things. One, it's not called "global warming" anymore for several reasons (one of which is that people, particularly in Canada, tend to think that'd be a good thing and two, the globe is not uniformly, or even entirely predictably, warming). The second thing I'll add is that even if you're inclined to dismiss the findings of scientists all over the planet, replicated over and over and over again, all you have to do is head north to see climate change in action. Ask some Inuit. Their oral histories cover off quite a period, and they're seeing unprecedented things of late.
Look, we can argue amongst ourselves as to what degree we're at fault for this climate change. And we can perhaps quibble with the models, most of which predict data so far in the future that their creators will be safely dead. But we dare not dispute the evidence in our very faces.
Human beings are nothing if not adaptable. But, to paraphrase the motto of LifeAfterTheOilCrash.net, we need to deal with reality before reality deals with us.
