This creates a false dichotomy between climate science and physics. Researchers studying the climate use physical models to do so. And their accuracy is not bad--100 years ago they predicted that burning fossil fuels would warm the climate, and that matches what we measure today.

The precision is low, though. That is a result of the chaos created by the immense complexity of the systems involved. We can't predict the precise path of an individual electron through a bar of copper either.

I know people that denie carbon dioxide traps heat and wish that basic science is a conspiracy.
