I have the impression that climate scientists have stopped trying to falsify their theories, mainly because you don't get funding for that in the current political climate (pun intended). And after all, 98% of climate scientists believe they should get funding and tenure.

Real science would be busy trying to falsify what "everybody" sees as facts:
Is there climate change beyond what has happened in the past? If so:
Is the increase in greenhouse gases the main or only cause of this? If so:
Are the CO₂ emissions by human activity the main or only cause?

If everybody really wants to "do something" about it, it would be nice to have some degree of certainty about what to do; we could be reducing CO₂ emissions while we should be telling our cows to fart less or be complaining to the sun about its activity.

Next, if everybody really wants to "do something" about CO₂ emissions, then there are plenty engineering solutions out there to do it, most of which have a worst-case scenario of "money lost, but no harm done". The fact that these available solutions aren't being implemented everywhere shows that few actually want to act even while being very loud about the need to act.

Follow the money.
