Dear Ts,
Global warming is not just a theory. It’s a statistical model. And it’s been ironclad for almost two centuries. Even super-computers have not found an improvement over the mathematical formula. The warming part has been observed over the last thirty plus years. That is a factual observation, not a theory. As Ujm mentioned how much warming has actually been observed, is in dispute. And what the cause is, can fairly be called just theory. And nobody intelligent is saying that the world will blow up.
