If you're looking to experience a "climate change" simulator, kind of, the game Oxygen Not Included is an interesting chemistry sandbox where you need to balance things like O2, heat, food, etc in a "terrarium" of sorts. The parallels to climate change are similar to real life--most of the game ending problems you encounter are from short sighted thinking earlier on/kicking the can down the road.

If you're near Lake Powell, you could also visit it right now and compare it to what you remember. Not a simulator, just a pretty scary real thing.

Gotta love the cycle 200 heat death

I found Half-Earth Socialism: The Game[1] to be fun for quite a few playthroughs.
