Tests Said to Tie Deal on Uranium to North Korea

1) What if a limited number of nuclear attacks could slow/stop/reverse global warming? Perhaps the limited destruction of industrialization and reduction of population very very quickly would actually save the planet (well, of a while, of course).
2) Will an asteroid hit hit us before global warming? What if preparing for asteroid defense is linked to global warming :-)
Ah, I have constructed problems I cannot possibly solve, let alone influence. Time to relax and play.
