Freeman Dyson: Getting Warmed Up

Here are a couple of Youtube videos with Freeman Dyson talking about Global Warming mania.

He starts out in the first video (on the left) talking about vegetation. He says you can't do good science without good data. He notes that the data on vegetation is sparse (as in almost totally non-existant). The money went into computer models instead of data gathering. It figures. Computers are sexy. Electronic wind vanes and anemometers are not. He also notes that the carbon in vegetation dwarfs the carbon in the atmosphere.

In the second video he says the real problem is not CO2 induced global warming, but CO2 induced stratosphere cooling which may lead to bigger ozone holes.

He ends with the fact that the lowest cost way to control CO2 in the atmosphere is not by controlling energy production and use, but by planting or cutting down plants. He suggests more irrigation. For that we are going to need cheap fresh water. Here is one way we might get it: Bussard Fusion Reactor.
