Environmental Rat-Holes, Part 2

Alright, let's have a little fun with this. The predicted global warming (according to the IPCC) over the coming decade is .17 degree C. For the world to somehow be able to stop that (extrapolating from the previous post to include all countries and to actually achieve this goal), the total cost would be approximately $540 trillion, or 80% of global GDP. Does anybody out there really think that this constitutes a good investment?.....................................................................P.S. And, yes, I ask you to compare that to the cost of doing nothing now and adapting to global warming if necessary. The Stern Report (a rabidly pro-AGW document) - according to this analysis, the cost of climate change would run anywhere from 1-3% of global GDP. So, even if we take the higher end of this projected cost, that would only be approximately $20 trillion, 96% less (or, if you prefer a ratio, 27:1), 96% LESS!!! I mean, are you starting to see the craziness here?
