I don't think anyone disputes that the globe is getting warmer. It's the
allegation that human activity is the primary cause of global warming that

All science is disputed, all the time. That's how science works.

Science does not "prove" things; that's for mathematics. Science develops a
hypothesis, tests it against the evidence and, if the evidence supports the
hypothesis, creates a theory that must be testable, predictive and falsifiable
to be accepted as valid. But no scientific theory ever reaches a point where
it stops being modified by new data and methods of study.

The theory of anthropogenic climate change has reached a stage where it is
generally accepted among the world scientific community as valid. Research
continues over many points still in contention, such as feedback influences.
That does not mean that there is any considerable doubt in the scientific
community that ACC is real. Those wishing to "shoot the messenger" often
resort to cherry picking facts from the various mini-controversies within the
overall research to cast doubt on the theory itself.
