It wouldn’t change that if what you claim were a fact. But if it were a fact:
1. The weather patterns almost certainly wouldn’t have radically changed in exactly the ways the scientists forecast;
2. We would need to radically revise physics and chemistry to explain why heat, gases, black-body radiation, molecules, and many more things don’t work they way they seem to.
3. We would have to have an alternative explanation for the tremendous heating of the Earth in the last several decades, and one consistent with the known facts.
