Eventually climate and weather modelers would like to merge increased resolution and added complexity and run the most complete models at 10 to 20 km resolution with the most accurate parameterization schemes.

There are still biases in models. There will always be biases in models. But the models are grounded in basic physics and they're tested against multiple data sets of observations, in terms of both the mean and the variability. Thirty years ago atmosphere-only models were run with prescribed sea surface temperatures. Now we're running fully coupled Earth system models for thousands of years, and the models keep getting better.
