INFORMATION Krugman and Climate Change Adaptation READ HERE
Paul Krugman has written an excellent review of his first mentor's new book. Dr. Krugman is a consistent thinker. He devotes merely two paragraphs in his long review to climate change adaptation. Below I supply it.In an urbanized world with multiple sources of food supply due to international trade in agriculture, I would like to see Dr. Nordhaus and Dr. Krugman explain which of these outcomes listed above is a "knockout blow" and how does this "knockout" occur? I would like to see these "macro economists" walk me through the micro economics of why optimizing households, firms and governments cannot adapt to these new challenges. Physical places will suffer (i.e if we evacuate Miami) but how do different households suffer? If households are expected to suffer, doesn't that create profit opportunities for those who can solve these problems? How far does human ingenuity go in offsetting Mother Nature? Are these Yale economists so pessimistic about human ingenuity? What is the point of Yale if its focus isn't to solve problems? (In this age of disclosure, I will reveal that Yale rejected my undergraduate application)."How much harm will this do? Nordhaus draws a contrast between what he calls “managed systems”—things like agriculture and public health, which are basically human activities affected by climate—and “unmanageable systems,” like sea level, ocean acidification, and species loss. Compared with some climate writers, Nordhaus is relatively sanguine about the impact of rising temperatures on the managed systems. In fact, he summarizes studies suggesting that agricultural yields will probably rise a bit thanks to one or two degrees of warming, and declares, “It is striking how this summary of the scientific evidence contrasts with the popular rhetoric.” (You see what I mean about his role as debunker—although he concedes that the costs become serious once temperatures reach levels that on current trends they are likely to hit late this century, and much more so at temperatures likely next century.) Health impacts, too, he views as modest, at least for the warming likely this century, declaring his overall assessment “similar to that for agriculture.”The bigger costs, Nordhaus argues, come from the unmanageable systems: rising seas, more powerful hurricanes, loss of species diversity, increasingly acidic oceans. The trouble is how to put a number on these costs—something he needs to do because, as I already suggested, his goal is to do cost-benefit analysis."
