I still wonder how a mind works that would prefer to believe in a discredited theory rather than letting go of it so it isn’t getting in the way of gathering obervations to form a new theory!!

“One of the main reasons for persistent skepticism is that people look at the evidence and find it wanting, they look at the AGW proponents and find misrepresentation of the alternative arguments, and they look at the emotional appeals and see bias. When people of science like RealClimate start worrying that their lack of results is due to being ‘unlikable’ and ‘poor communicators’, its my experience that the real problem is the use of subjective vehicles to back up inconclusive science. Skepticism is healthy, and the way for AGW proponents to further their work is through greater openness and objectivity, not stronger emotional appeals.”

He is a Malthusian which is one of the dumbest philosophical positions one can take about humans because it only looks at natural limitations; the history of humanity is a history of circumventing natural limitations by technology; it is that technology which has enabled nature to be kept at bay and for the relative prosperity of the last century to be achieved. By disavowing that technology in a way which goes far beyond any sword of damocles moderation of technological application it is fairly clear that Holdren is a misanthrope who thinks he is better than other people.
