A chill factor is needed for the Iranians, who in all likelihood will drop a nuke on Israel, from Syria.
Then the Faisel will hit the fan. So we need to know how to survive a nuclear winter, the way the Clovis Pointers did but Red Stoner did not. Maybe the Clovis people invented long johns or something......central heating in log homes??
A nuke won’t do it. A thousand nukes have been detonated with no noticeable effect on the climate.
