It might suprise you, but I would agree with about everything you stated
But I am not convinced that global warming of a few degrees over the next centurey and a half will lead to a global catastrophy.
It is "the sky is falling!!!" part of the argument that loses me. It smacks too much of E.P. Grondine's arguments visa via Cometary impactors...
I'm not ruling it out entirely, I just am saying that the predictions of gloom and doom are based on some pretty weak assumptions about the environment, and more importantly, the ability of ecosystems to adapt to changes of one or two degrees averaged over a period of decades.
