But don’t the climate scientists’ computer models prove that carbon dioxide emissions from burning fossil fuels are causing climate change? No. First, no computer model can ever prove anything (see the definition of “science” given above). Second, we do not have the capability to model a system as complex as the earth.It has been said repeatedly, and I agree, that one huge problem that the pro-global warming people have is the tendency to use computer model results as if they are data. They are NOT! Something resulting from a computer model does not dictate that that same thing will be observed in nature. And guess what? Predicted rises in global temperature have not occurred in the last 10 years.
