Use your intelligence to get a degree / study in the relevant earth science fields along with physical engineering study. Work towards geoengineering. Full control of all the earth's natural systems (climate, evolution, aging, lifetime of the sun...) is humanity's destiny, best get working on what we can now. Of course political activism is available, but the question then is where to push on that front. Enough people are working on awareness, probably not enough are working on amending the UN's Convention on Biological Diversity and London's Convention on Dumping of Wastes at Sea to allow and encourage geoengineering on an international scale in the first place. Something as simple as dumping lots of iron in the ocean ("iron fertilization") could be all we need to do in the short term, but there's a lot of resistance to it. If I were interested in this path I'd focus on removing that resistance politically and/or scientifically.
