Treason against the planet?

I have not posted for a couple of days as I have been incredibly busy. However, Paul Krugman’s column in the New York Times on Sunday particularly amused me. The Nobel prize winning economist denounced the “deniers” who opposed the Waxman-Markey climate change bill as guilty of “treason against the planet”. It is hard to see what this means. How can someone be loyal to what is essentially a lump of rock?

It is certainly possible to be concerned about the impact of environmental degradation on humanity. But “treason against the planet” is absurd.

Krugman is undoubtedly clever but his argument on this point makes no sense.
