It is time to stop quivering in our boots in pointless fear of the future and just roll up our sleeves and build it.

The Two Tailed Beast

Somebody with an interest in economics, one Tyler Cowen, a.k.a. "Marginal Revolution" gets this much right:
Make of climate models what you may, there is lots of evidence that a) biodiversity is being hammered, and b) climate change will bring desertification, drought, and possibly coastal flooding to many parts of the world, among other dilemmas. I don't have a lot of faith in the exact predictive powers of climate models, or for that matter economic models, but uncertainty about outcomes should make us worry more not less. Uncertainty usually has two tails, not just one.
Interesting comments, too. Comments off here; please comment on the referenced article.
