Freeman Dyson on Climate Science

Since climate "science" has devolved into a political issue, let's first identify Dyson's politics:

An Obama supporter who describes himself as "100 per cent Democrat," Dyson says he is disappointed that the President "chose the wrong side." Increasing CO₂ in the atmosphere does more good than harm, he argues, but it is not an insurmountable crisis. Climate change, he tells us, "is not a scientific mystery but a human mystery. How does it happen that a whole generation of scientific experts is blind to obvious facts?"

Since he disagrees with Obama he's obviously a racist, right, lefties?  Or do you have another reason to discount him?  And you're going to have to disagree with him:

He pours scorn on "the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models".

"I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry, and the biology of fields and farms and forests," writes Dyson...

"Many of the basic processes of planetary ecology are poorly understood. They must be better understood before we can reach an accurate diagnosis of the present condition of our planet," he says.

The models are primitive.  Many don't even account for water vapor (our largest so-called greenhouse gas), and none of them has predicted our current 17-year lack of warming.  Much like the "young earthers", who think the earth is 6000 years old, there's enough evidence here to question the orthodoxy.
