I question the 90% chance assumption. No we should not bury our heads. Nor should we require mandatory federal inspections of homes and cars for energy effiiciency. Nor should we have utility companies control thermostats in the homes of private citizens.
The only point I would make is that the science is not there yet. Not enough to base life changing public policy on. We are not short of government or private funds for continued research. With the right methods and transparency, we can come to the right understanding and then consider our options. This will certainly tak place before Dornoch goes under.
