Water vapor is a vastly more effective green-house gas than is carbon-dioxide. But the feedback effects are very complex. For example, water vapor should have a green-house effect, but it also condenses, forming clouds, which give an earth-shading effect, and water freezes to form snow, which is another great reflector. These processes swamp any CO2 effect. It is clear that the models cannot handle this complexity accurately, and that the predictive value of the models for several decades has been unimpressive to useless, and certainly not sufficient for making policy decisions.
The final reason for abandoning the global warming hysteria is that the countries of the world will not obey a regimen which, at tremendous cost to themselves, will yield a barely noticeable result. Beijing, capital of the country which soon will have the biggest economy in the world, will not even clean up its own air pollution!
Will countries which stumble when trying to control obvious problems like malaria, Ebola, the Russians, restraint of Islamic terrorism, merely balancing national budgets — will these countries, I say, suddenly unite to fight a dubious climate problem? We are speaking of governments which are largely corrupt, cannot control crime, cannot protect their borders, are either threatening or threatened by their neighbors, &c., &c., are they going to be competent to control the thermostat of the Earth’s climate? Even presuming that they knew what they were doing?
Of course not.
No argument from me.
Countries, and individuals, are blithe about dismissing the costs of “controlling global warming,” or anything else for that matter, up to the point they suddenly realize the cost, or a lot of it, will be paid by them.
Suddenly their POV changes. People are always insouciant about spending what they think of as other people’s money.
