Forecast: The Consequences of Climate Change, from the Amazon to the Arctic, from Darfur to Napa Valley by Stephan Faris. Faris takes as a starting point the scenario that the world can find policies that limit global warming to about 3.5 degrees Fahrenheit, which appears to be something that humans and most other living things can adapt to without devastating economic consequences. I think you will find Ron's perspective interesting and his writing to be clever and pointed.
