Every single scientific society states AGW is a fact. Every single National Academy of Science states the same. Every single major university likewise. Irregardless of the nation or political form of government, there is an internationaly overwhelming consensus among scientists that AGW is a fact.
I think it's reasonable to say that the idea that there has been a warming trend recently has been established as a fact. But the issue I addressed in starting this thread is that of cause and effect.
Whoever authored Chapter 9 of the IPCC Physical Science Basis conceded that unequivocal attribution would require experiments that are impossible to conduct. I think it's pretty darned reasonable to say that's conceding that a cause and effect relationship between a warming trend and human activity has not been established as fact. I think that if something is established as fact, it can be stated unequivocally.
Not that I'd agree with them if they did say the cause and effect relationship had been unequivocably demonstrated. But I'm grateful that whoever authored that chapter had enough integrity to state that it hasn't been.
