If you read just one article about climate change this week, make it Dave Roberts' piece on the climate science vs. climate economics. Climate scientists are becoming increasingly worried as the evidence mounts that our current emissions path is leading us to some of the worst-case scenarios that climate models project -- sea level rise, increased precipitation, more severe storms, and crippling droughts. Meanwhile, economists' models show a world growing more prosperous, with economies slightly inconvenienced by the fact they'll eventually have to adapt to climate change. Is something askew in this picture? Methinks so.
