That is not a good comparison. Scientists that disagree with climate change are like a couple percent at max. Meanwhile nearly every economic topic, including price controls, would have double digits of economists disagreeing with it. Economics is not a hard science where you can take anything in absolutes.
Disagree. Climate science and economics are quite similar in this context, in that both an economy and a global environment are so massive and massively complex that neither can be isolated and studied in a controlled environment.
In such cases, when there does exist a consensus, it's probably correct.
