If you state that:
since 1990 4,000 papers expressed an opinion on the cause of recent global warming. Of these, 97% agree, explicitly or implicitly, that global warming is happening and is human-caused.
I will agree with you. However, that is all it means. That does not prove anything, not that 97% of scientists agree with it or that global warming is a calamity or it is a problem.
There are real scientist with prestigious credentials that disagree with global warming.
