Krugman on Global Warming

Krugman makes a good point, the whole country came together in the fight against terrorism, why not for global warming?

The cost of reducing carbon consumption is trivial to the cost of a single war. Yet for some reason the militarists never seem to have the slightest hesitation about spending a trillion dollars or so on a war.

Since supplies of carbon fuels are finite it is a question of when, not if, we change consumption patterns. And carbon addiction was and is the root cause of all the issues in the Middle East.
