Flight simulators can be real world tested to see if they match the flight dynamics of real aircraft.
And, yet, they never are 100% accurate. Flight dynamics precision improves, over time. Sometimes genuine bugs are found in the code: both fundamental flaws and graphics glitches. Sometimes control layouts will be subtly different enough that the trainer's own muscle memory causes them to be used erroneously.
Should we dismiss flight simulation technology as useless, simply because it is never 100% accurate?
If we assume (for argument's sake) that all the flaws in the papers you linked to, were indeed genuine flaws in the models we are using: Guess what?
We can change the models to correct for them! And, thus, the models would be even more accurate.
Even if they never reach 100% accuracy, they are still useful.
You cannot build a planet to test your climate model.
But, we can test their predictions on the planet we are living in, now:
* We can see if the model accurately extrapolates data from the more-recent-past using only data from the distant past.
* We can see how accurately the model makes predictions at several points in the future. If there is an increasing error rate, over time, we can investigate what is causing that. And, by doing so, we make new discoveries about things that affect the climate.
The models are all based on well-understood principals in climate dynamics, and the laws of physics. Accuracy ranges, in each of the principals used, are generally well understood by the scientists that use them.
Climate models are not magical "black boxes" that make simple assumptions. They are basically computer models of climatology concepts.
No flight simulators have no relation to computer climate models nor the results being achieved by using them.
So, in principal, this is wrong. The opposite is true, from the perspective of computer science: Climate models are models of the climate, just like flight sims. are models of flying.
And, I remind you that it is those computer scientists are continuing to make progress in problem solving. You know what does
not make progress in problem solving? Something that is not a model.
Besides, if we did ditch the climate models,
what would you replace them with?! What alternative tools are climatologists supposed to use to conduct their studies effectively and efficiently?!
You wouldn't ask pilots to train in cardboard boxes, would you?!
