    At a rate never before seen in the history of the earth.  Take our 4C and stretch it over ten thousand years, NP

    Actuall, the climate has been in a stable period for the last four thosand years. The observant will notice that corresponds to the age of agriculture.

      it's been getting warmer and colder on a chaotic basis. It was warmer than it is now a thousand years ago and cold as hell two hundred years ago. Now carbon pollution isn't a GOOD thing, and if you compare the climate from a few centuries back it IS quite a bit warmer now...but...the end pleistocene climate change, and that includes the younger dryas, is a hell of a lot quicker.

      So what what climate do you want?

        Another mass extinction event doesn't sounds like a good plan does it?

        The constructions of the record from a thousand years ago out it 0.4C cooler than now

        •  That's not what I read....n/t (0+ / 0-)
          •  Here's the graph (0+ / 0-)

            wikipedia has replicated these  I'm sure there are other reconstructions.

            The point about the Younger Dryas is a good one that made me think.

            I think my answer is that unlike the Younger dryas and other catastrophes, this time, we understand what is causing the mass extinction, we understand that there are potentially disastrous consequences for civilization (humantiy itself will survive since we're ridiculously widespread primates), and we know we can prevent it.

            If it were happening and we were powerless, that's one thing.  To create such potential disasters though seems very irresponsible.

            •  Oh, THAT one.... (0+ / 0-)

              It was that one was created for Al Gore and includes a paranoid projection ending in 2040. The projection part was censored and magically became "actual data" for the current situation.

              I agree with you as to your last statement.

              Rapid climate change has had major reprocussions over history. In fact it may have STARTED history with the destruction of north africa and the creation of the sahara and arabian deserts in the 4th milleniumn BC. The extremely rapid global cooling of the fourth and fifth centuries AD may have caused the end of the Roman empire and the rise of Islam. Global warming may have ended the classic Mayan civilization and Teotauacan.

                I see.  It's all a paranoid projection

                GOtcha.
