"I think theory switched to fact in the last few years. "
Theories do not become facts. Facts are observable phenomenon which are interpreted within a philosophical framework to produce a theory. If more and more people agree, it does not become a fact. If more and more facts are interpreted to give weight to the theory, it does not become a fact. Man-made global warming is not a fact. Climate fluctuations have been recorded in places over a relatively short period of time. Those temperatures are the facts. Gathering more temperature recordings does not reveal the cause of those changes.
