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.
