This is right. Nor is there going to be any such system. The climate is a complex system, meaning it's fundamentally not amenable to simulation. All the models are toys compared to the reality. None of them even attempt to actually simulate what's going on. Not only is it impossible because we don't even know what the phenomena are, it's extra impossible because there's not enough computational power. I doubt humanity is capable of accurately simulating the sugar in a stirred cup of coffee, much less figuring out what's going to be happening with the atmosphere tomorrow, much less 30 years from now.

The models are (unavoidably, necessarily) just toys. They don't predict the future. Anyone who tells you that they are predicting the future with them is malicious or extremely naive. The models just masquerade as science to support political goals.

What political goals? Source would be appreciated as well.

Yes, not screwing up the biome on which we all depend to live (and countless other species) is definitely a political motive.

Is there a problem with that? Don't think so.
