Global Warming: Yes, it happens. The usual result, at least in the civilized worlds, is massive technofixes, from the brute force (say, giant orbiting sunshades with solar panels on the back) to the subtle and ecological; usually coupled with an extensive program to move industries off-world, into orbit at the very least.
These tend to be the preferred methods because people are perfectly aware that anything you do to atmospheric composition is the relatively easy version of this problem to solve. But at least visible from that point on most tracks of technological development is the second heat crisis which is about literal waste heat being discharged into your atmohydrosphere, and the Second Law of Thermodynamics says there’s bugger all you can do about that, short of moving the work being done elsewhere, or giving up on this whole technological-civilization thing altogether.
And competent societies can at least try to think more than a decade or two ahead.
