The Gingrich development is particularly interesting. I guess he decided that the climate change debate was more political than scientific in nature.
Or it could be that climate is on the backburner due to a crap economy, idiotic current energy policy, and the GOP base isn’t champing at the bit to implement carbon taxes. IOW addressing climate comes after fixing energy policy, which is a reflection of what can be realistically addressed and in what order. Pragmatism rules.
Claiming that re-ordering the priority list indicates a rejection of science is simply dishonest.
