Wishful thinking (and an argument in favor of making efforts to actually cause some anthropogenic global warming): a new ice age would be far more catastrophic to civilization than a 4 degree celsius rise in mean global temperature.
Inasmuch as the climactic record is consistent with a sudden shift from warm conditions to ice age conditions over the timescale of a decade, I wouldn’t be entirely shocked were most of us posting here to live to see the start of the next ice age.
Should be starting anytime now!
Where I live, the ice used to be at least 1,000 feet or more thick. I would rather have to be concerned about alligators in the swamp behind my house that have this kind of ice return.
Those empty cities in China may have been outfitted with district heating sourced from peripheral power plants yet to be sited (nuclear). The Chinese may be the ultimate preppers as they have tripled or more grain imports but are not suffering any domestic production issues. U.N. analyst are puzzled. Only connected need apply.
