Hi Bizi,
I don't buy into global warming insofar as panicking about the ozone layer. I am against pollution just on principle, but I suspect there are larger forces at work, natural ones, responsible for the climatic changes.
Before we were around to pollute it, the Earth went through a few ice ages. When each ice age ended, what would you call what happened? I'd say "global warming" might be an apt term.
I do think the earth's weather is likely to undergo variations that take longer than one of our lifespans. So sure, I buy into the idea that we may be in for warmer weather... it certainly seems to be that way. Not that I really want to be reminded...
