I'm going by what he said. He said he would rather drown than live in a more crowded area. Which is patently absurd.Chalnoth, don't be stupid. Few if any people will die in the developed world from AGW, and the cost of saving those that do by CO2 reduction will be >100x more than the cost of saving people dying from other causes.
Anyway, it is true that there won't be that many deaths in the developed world. You'll get a few more due to additional extreme weather events, such as heat waves, floods, and fires, but not all that many. Deaths aren't that significant of a reason to pursue AGW mitigation.
Yes, I know this is your schtick. It's still as wrong-headed as it was when you first posted it. Every ounce of CO2 we emit today sticks around for hundreds of years. Plus, we know that the Earth undergoes dramatic changes in climate at specific tipping points, but we don't know precisely where those tipping points are. Running into such a tipping point would be an absolute disaster, and should be avoided at all costs.We're not going to avert this cost with GHG reduction. At best, we can reduce AGW by a few percent by spending trillions of dollars (at today's non-nuclear green energy prices). Marginal benefit does not come within an order of magnitude of marginal cost right now.
So we should most definitely do everything we can (within reason) to reduce CO2 emissions now. Obviously we won't be able to do tremendous amounts. But spending a couple percent GDP is well within reason.
