I'm quite convinced which of the two forces: Nature or Mankind, wins in the end. I think a key to this dilemma is to really understand that it is us and our children that will loose, not Nature. And in a way, declining weather is quite good to build that understanding.
I read in Scientific American a few years ago that actually, the Co2 problem isn't really a "long-term problem" for Nature. The excess Co2 will be absorbed by the oceans, the only small problem is that it takes a couple of hundred thousand years. (Poor humans.)
