Or that it is occurring and man has much to do with it, but that it is in fact a Positive Good?

(Don't skewer me, I'm not making that assertion, but I've heard it.)

For my part, the contention is that one is looked at askance for allowing that there may be any contention at all. In the light of decades of revision, re-evaluation, recanting and recalculating -- which is after all what good science has always done and always should do -- a little humility would be reasonable. But when science gets hijacked by politics (on both sides!!) this gets replaced by the attitude that we've got it incontrovertably, inarguably by-god Right this time.

The whole conversation is so poisoned now, that I suppose we'll have to wait another 43 years to know which set of pronouncements to snicker at (if not both).
