Without taking a position either way, my understanding of the skepticism is not that warming is not occuring, but rather the degree to which things that humanity can control influence that warming (0% to 100%).
That's a fairly recent goalpost move as "warming is not occurring" has become an untenable position.
First it was: it's not happening.
Then: but how much?
Now: but can we affect it?
Soon it'll be: are we sure it's a bad thing?
Then it'll be: it's bad but it's that other guy's fault.
Contrarianism is a mouse wheel, not a ladder.

Clarification edit: Meaning I think there is a better argument in the polemic (I'm not suggesting the answer)
It's not a question of evidence at this point, it's a question of the limitless realms of ignorance.
