Roy Spencer, Ph.D. Meteorology: Given current technologies, it makes no sense to destroy $100 Trillion in wealth this century for an unmeasurable reduction in warming. As a lukewarmist I believe (but can’t prove) that humans are probably responsible for some of the recent warming (which has been mostly benign). But until some new energy technology comes along we are stuck with fossil fuels for the foreseeable future. The oil industry’s use of fracking has already reduced carbon dioxide emissions — through a switch from coal to natural gas.
