Krugman on Climate

Paul Krugman has a great column on climate change today.  This leapt out at me.

“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.”

And, not parenthetically:

“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.”
