Didn't mean to be too challenging, but you can imagine how frustrating it can be to hear the real insider talk and then hear non-experts discuss it.

There is definitely a chance that there is a natural component to warming. However, there is little clear evidence of that. There is, however, a much clearer correlation with human activity. All aspects of the phenomenon are unprecedented in the geological record when the time scale is taken into account. No natural phenomenon has happened so quickly barring things like comet strikes which, of course, are far faster. The rate of change is staggering and it matches very closely human activity.

My point is not to convince you of what you are largely already convinced of, but to point out that natural phenomena don't behave this way...though SOME natural component can't be ruled out. But the human caused aspect seems dominant. I wrote something about how unprecedented things are and how well correlated they are with human activities here.

I don't argue that we need to adapt. But many things we do to adapt would also help mitigate warming. Also, without mitigating what we are doing, our adaption will have to be running to keep ahead of an accelerating process (acording to most, though not all, models). Also, many things we can do to EITHER adapt or mitigate could be done in a way that our economy benefits. The right wing myth of "economy or environment" has been one of the most desructive myths they have come up with. We need to stop thinking in those terms and think economy AND environment.

By the way, if you want to see what the real scientists are saying, they discuss all this on Real Climate.
