Climate economics is stuck in an alternative universe where societies do not adapt. That's not useful, I explain @WSJOpinion. Come for the part where Mongolian incomes surge past American ones, stay for the Michelle Pfeiffer reference. https://t.co/sKb8wq8b1J— Oren Cass (@oren_cass) March 12, 2018
Excerpt:
This has nothing to do with the soundness of climate science. The games begin when economists get their hands on scientific projections and try to translate temperatures into human impacts. They conduct statistical analyses of the effects that small year-to-year temperature variations have on things like mortality and economic growth, and try to extrapolate to the effect of very large, slow shifts in underlying climate. This creates absurd estimates that ignore human society’s capacity for adaptation. This is the latest iteration of the same mistake environmental catastrophists seem insistent on making in every generation.
The best illustration lies deep in a 2015 paper published in Nature by professors from Stanford and the University of California, Berkeley. They found that warm countries tended to experience lower economic growth in abnormally warm years, while cold countries experienced higher growth in such years. Applying that relationship to a much warmer world of the future, they concluded that unmitigated climate change would likely reduce global GDP by more than 20% from what it otherwise would reach by century’s end.
