You think the evidence for human induced climate change is 'not incontrovertible' - which is a stupid standard since there is no science anywhere in the universe that has ever or will ever meet that standard.
On the other hand though - the evidence for any other theory is completely and utterly non-existent.

Massive amounts of physical evidence from hundreds of different scientific disciplines all supporting the most intensively tested theory in the entire history of science - versus... squat, zilch, nada.

There is no such thing as incontrovertible evidence in science. There is such a thing as strong evidence- and the evidence for man-made climate change is overwhelmingly strong, indeed it's the best supported theory in the entire history of science itself - since never before has this much money been spent to try and disprove a theory, all to no avail. In fact, the studies created to disprove it have all been either easily shown to be bad science, or ended up confirming it.
