There is no other way though. Climate change is not a technical problem, it's political. We've had the tech to fix climate change for long time, we know how to do it, that part is quite easy and obvious, we are just not doing it.
You can't say "other way" when you're comparing to something that isn't a way in the first place.
Climate change absolutely is a technical problem and not a political one. It's about the cause and effect patterns of actual weather phenomena, and has nothing to do with conflict resolution within human societies, or anthropocentric psychosocial rituals.
We don't really have the technology to purposefully engineer macro-scale climate patterns, and we absolutely do not have the technology to secure wide-scale cooperation among vast numbers of people with different value systems and incentive structures. We've never had that.
