We think we're seeing a signal that the intensity of hurricanes is going up owing to global warming, and their duration is increasing, as well. And this has us worried. In terms of the influence of this on the rest of the world, I think it can't be stressed enough that in the United States we have been enormously successful in reducing the loss of life. As horrible as Katrina has been - and it is horrible, sort of a worst-case scenario - so our problem is economic. That's our big problem. But in the rest of the world, in the developing world, the problem is loss of life.
