Funny Christopher Hitchens a hard leftest is slamming Global Warming as total myth... and now Alexander Cockburn who in so far left he makes Hitchens look, politicaly, like Rush ...
I chalk it up to Cognitive Dissonance.
The old left has spent the last 40 years opposing nuclear energy because it was a lower cost option to fuel capitalism. But since the neo left and assorted opportunistic political hacks have completely jumped the shark on this global warming crap, the old left has no response other than the obvious --- freeze to death in the dark.
That's not a good sales pitch.
