Global Warming

I would imagine its generally agreed that the earth will be warming a few degrees over the next few decades. I don’t want to get involved in the dispute about whether this is due to natural causes, is caused by us, or is some combination of the two.

But (and I’m sure someone else has done this before)… how should the average American react, from a financial perspective? Assume they can do nothing to effect a change and that global warming is coming. Assume they make the median income for the US, and have a small amount of savings. What should they be doing differently? What investments should that person make? Should that person move, and where to? What about jobs – are there jobs whose prospects are going to get better or worse as a result of global warming?

Your thoughts? (Let me throw in one ground rule – keep this relevant by sticking to what you think are feasible suggestions.)
