It will be really interesting from a Western perspective to see if the rest of the world, the part that actually makes up the bulk of the population of humanity, and the portion of the population who will be most impacted by climate change, take unilateral actions to geoengineer or design systems to alter the climate.

I can't picture the US and EU doing anything other than posturing and use the idea of manipulating nature as a political tool to promote or attack and make people scared so some asshole or another can claim power for a day. But nations like China and India who have the most at stake are fully capable of taking action without a unified alliance.
