What are those other solution ? Nuclear, in my opinion, is the only solution that doesn't require the developed world to lower it's standard of living.
The "ultra-rich" and their "pocket puppet" politicians and corporate entities (who cause the "Lion's share" of the problem are the ones who most (and most immediately) need to "lower their standard of living" to combat this particular problem. They ain't gonna do it. Period. Anyone who thinks they will is just as insane as they are… Thus, we're pretty much screwed no matter what the rest of us do. Those who can improve the situation will absolutely not do it. It would cut into their "infinite profits from a finite planet" fantasy.
