The predictions of doom that are driving the public policy changes being demanded by climate change alarmists do. And the models are wrong.

This is because the climate has gone through major changes before, and we can see how much of an initial push it took, and what happened afterwards.

Trending to a local minimum or maximum in modeling can be caused by small changes at certain points dependent on time and be completely negligible at other points. Without understanding the model: 1. We can't even pretend to understand causality 2. We can't infer the complex state at an individual time or even the magnitude of a push.

This is not correct. There is plenty of data in climate science. There just isn't a good enough understanding of the underlying mechanisms to make predictions that are accurate enough to drive multi-trillion-dollar public policy decisions.
