Nuclear Winter technically a bigger threat to civilization than Global Warming?

That’s the impression one gets from reading recent research about the potential effects of a much smaller nuclear exchange than usually envisioned during the Cold War between the U.S. and the USSR … together with the continuing emphasis the Doomsday Clock guys put on nukes vs. GW.

(I have to note the irony that the scientists who GAVE us nukes and dangerous technology are the ones who now demand that THE REST OF US DO SOMETHING to save them, er, the world, from catastrophe!  ‘Stop us before we kill again….’  They could stand more self-restraint, less hubris, better ethical training, themselves.  But like Republicans with Reaganite financial deregulation, many of these folks seem to think the solution to the problems of technology is MORE TECHNOLOGY.  Another funny thing: For most of my life, I thought the expression “mad scientist” indicated anger.  It’s only recently that I realized it means they’re crazy, just like in Mad Cow Disease! [No, I didn’t just learn that mad can still sometimes mean crazy; just that it did in those two particular uses.])
