The Talking Dog has a little post about how the nastyness of global warming could possibly be extreme and could possibly happen sooner and not later. Nobody can really guess the likelihood of such doomsday scenarios, but there are plenty of important climate regulators, such as the Gulf Stream, which could conceivably reach their "tipping point" rather soon and have diastrous effects.
There are three basic issues. 1) Is global warming "real?" 2) Is it caused by human activity? and 3) If the answer to 1) is yes, no matter what the answer to 2) is, is there anything we can do about it?
The position of the Right seems to be 1) until you throw enough science at them, and then they retreat slightly and say the answers to both 2) and 3) are no.
But, anyway, if the excrement really hits the fan I'm sure, as is always the case, the mea culpas will be loud... (not)
