Jonathan Chait discusses how the arguments of the Climate Change deniers have had to change. It used to be they insisted the climate was not changing. Now, they kinda have to argue that it is changing but nothing human beings can do can stop it.
Here's my question: If nothing can be done to stop it, shouldn't we now be spending tons o' dough to relocate homes, build dams and levees, install new drain systems, etc.? Hurricane Katrina caused over $100 billion in damages. If you'd known it was coming, might it not have been prudent to prepare better for it?
