Cassandras of Climate

Today's column by Paul Krugman is great:

For three decades the dominant political ideology in America has extolled private enterprise and denigrated government, but climate change is a problem that can only be addressed through government action. And rather than concede the limits of their philosophy, many on the right have chosen to deny that the problem exists.

So here we are, with the greatest challenge facing mankind on the back burner, at best, as a policy issue. I’m not, by the way, saying that the Obama administration was wrong to push health care first. It was necessary to show voters a tangible achievement before next November. But climate change legislation had better be next.

And as I pointed out in my last column, we can afford to do this. Even as climate modelers have been reaching consensus on the view that the threat is worse than we realized, economic modelers have been reaching consensus on the view that the costs of emission control are lower than many feared.
