Wasn't it just a week ago we discovered that widely used models were significantly underestimating CO2 absorption by plants?

The models may be perfect or imperfect, either way the temperature is still going up.

- "Models say X is happening."

- "Well, isn't there this specific problem with the model?"

- "It doesn't matter, because X is happening"

Not sure the line of logic follows there.

your argument has an invalid premise: "Models say X is happening." It's not the models that are saying X (temp goes up) is happening, it's empirical data.

A better argument is:

- We observe X is happening

- create a model of X happening

- use model of X to predict X in the future

- model of X might be or might not be flawed

- meanwhile, X is still happening in the real world

It’s also interesting that this site has been having a collective orgasm over models that frequently give wrong answers for at least a year now. When climate is involved it’s suddenly a big problem.
