There are in the form of simulations. You can measure many effects like light absorption directly and put it in a simulation.

Discrepancies to reality can be investigated and used to make the model better.

You can then use the model to see how things would be with more or less CO2-emissions.

Whether a model predicts the outcome of a simulation has no bearing in determining whether either correspond to a future reality.

Running a simulation might be useful for directing scientific research, but it is not science.
