A lucky and resilient few of us, with good advance planning and community outreach, will probably survive the climate predicament. But WW III? A self-accelerating nuclear exchange would engulf the entire planet. If there were any survivors left, they would envy the dead. No thanks! I'll happily put a plastic bag over my head and seal it with Duct tape if WWIII breaks out. Maybe a handful of sleeping pills in advance, just to hasten the process of recycling myself!
