> Since when did science become about predicting what will happen in the future?

The very definition of science is making testable predictions.

I 100% agree. But you're missing the point entirely. The hypothesis of the mechanics climate change have been tested and are provably true. What has not been born out and is definitely not a testable prediction is whether certain measure are enough, that particular weather events are due to climate change, that humanity is likely doomed, etc. These are emotional responses not testable predictions.

Modelling has its limitations but those are well understood by the people building the models, which is why they predict a range of outcomes and uncertainty rises with time. Most of the uncertainty in current models has to do with the complexities of cloud formation.

We've had usefully predictive models for over 50 years now. The first real paper model from 1967 successfully predicted warming up to the current day.
