This isn't exactly what you're looking for, but climate change is probably a solvable problem with the right technology. My personal favorite idea is a giant set of solar shades [1]. I guess for that you should be watching for starship news at something like [2]. Other examples of relevant technology would include things include like fusion, superconductors (which are really a subset of fusion ;)), co2 extraction (which only makes sense if you have excess energy), and so on.
