    Suppose we solve the whole AGW problem tomorrow and drive CO2 concentration back down to, say, 350 ppm.

    What happens when we slip into the next Glacial period? Our interglacial time is just about up--though it could possibly still linger for up to 4000 more years.

    Not to say "no problem, no worry," as climate change (particularly, rapid climate change) can and will wreak widespread havoc. But, "death of the planet"? Hell, we could do that with a nuclear war last century.

    And God said, "Let there be light"; and with a Big Bang, there was light. And God said "Ow! Ow My eyes!" and in a flash God separated light from darkness. "Whew! Now that's better. Now where was I. Oh yea . . ."

      Natural processes have had a cooling effect for the past several thousand years, but if humans did not exist, it would still be something like 15,000 years to the next major glaciation.

      A small amount of greenhouse gases (less than what we've already emitted) would completely counter that, though.  We've already revered 6,500 years of cooling in just the past 50 years.  At this rate, we are headed back to temps 10C warmer than those in which all of civilization developed.
