They will be remarkably incurious about whether anything was actually changed.

It isn't that the ecowackos will be remarkably incurious about whether anything changed, they don't care. In fact if their policies actually solved the "problem" they would be out of work, so "solutions" that don't actually fix the problem are to be preferred. Then they can come up with new solutions, which won't fix the "problem" either.
The objective is to have something further to advocate, more laws, more restrictions of individual rights, more power to be assumed by the government, which they, of course, will control.

You're right about the ecowackos. Global warming is just the latest social myth they've created to drive their agenda. The myth of depleting resources was becoming less effective; as all of the doomsday predictions were proven dramatically wrong.

Interestingly enough, many of the doom-sayers still hold to the scarce resources myth; as well as the global warming myth. Lately, when confronted with a global warming true-believer; I remark on the high price of oil, and ask whether the world is running out of fossil fuels. "Of course we are" is the usual response. My rejoinder is to say something like: "well that should solve the greenhouse gas problem". Then, I like to stand back and watch the smoke rise from their ears.
