Stupid.

We're going into a global cooling event because of lowered solar activity, and The Messiah is contemplating shooting pollution into the atmosphere to block solar radiation and cool the earth's air.

Idiot. Yes, the sea ice is retreating. Yes, the oceans are warming. That does not mean that we are about to have catastrophic, planet-destroying global warming. Look back at the geological evidence around the prehistoric ice ages. Yes, there was a lot of ice--but it was in glaciers. On land.

Evidence suggests that the oceans were warmer then than they are today. Evidence suggests that warmer oceans were the only variable that prevented a mass human die-back: warmer ocean currents kept the coasts livable when continental interiors were ice-locked. Warmer ocean currents allowed for the hunter-gatherer societies to find food enough to keep a breeding population alive and healthy.

Warmer oceans with limited sea ice is not a sign of cataclysmic global warming. It's a sign we're in for a cold, cold time, coming up.

If you'd like to read a good explanation of how that model works, even if it is in a work of fiction, read John Ringo's The Last Centurion. And curse, because rather than the socialist fuck-up Ringo envisioned, we've got a national socialist fuck-up who happens to be stupid as well as malicious.
