Have you actually looked at it before you replied, or are you just assuming it?
Fortran is terrible for the scale of those projects, and it shows.
I can give you concrete examples straight from GitHub. Accuracy isn't relative it's absolute. You're not comparing accuracy to other models, you compare it vs reality.
It is a known fact the results of different climate models diverge. There's ongoing research as to why this is happening, lookup CMIP6. Many models also required flux adjustment to stay stable over many years of simulation (although at least that problem is improving).
It's really hard to test these models on the scale of the effects climate change.

- machina_ex_deus 4y agoYou still didn't answer me whether you've thoroughly reviewed their code before dismissing my comments. Did you? You can approach it as an insider researcher "on their side" and try to correct it, but the problem is just so big you're not going to get flawless models without time, and they have already shrugged serious problems in the past with "flux adjustment". You'll get endless errata and retractions but you'll never get a narrative shift. Or you can try to approach it from the outside like countless scientists have done and get called oil companies shill, climate denier and what not. The academic "climate" around it is very "hot". So eventually you just go and forget it and do something productive with your life instead of literally fighting windmills. (And I did mean literally as a joke about renewable energy).
