The world famous physicist Freeman Dyson discusses Global Warming with a twist, at Classical Values.
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.
The problem for political environmentalism is that Dyson takes a broad view of the issue when a narrow, dogmatic view is necessary to advance the current policy agenda. Starting from the premises the discussion rapidly escapes the confines of the standard Global Warming narrative. That is to say it escapes from its political prison. That raises an interesting question about the prescriptive policy changes being promoted. Are they actually based on the correct model? And if they are predicated on the wrong model would they have the same effect as swallowing the wrong medicine would have for a patient? If environmentalism were about science first and politics afterward the question would be easy to answer. Alas, today we live in a world of post-normal science.
The weather is a complex and nonlinear system, and the solutions advanced to solve "Global Warming" don't seem to take that fully into account. We will inevitably learn more about the environment as time goes on, and some of the facts will probably be at variance with the Global Warming narrative. Ideally we should adjust but I'm afraid that politics will create policy rigidities which will stifle movement when a rapid decision cycle is necessary when attempting to deal with any complex system.
