Yep. I'm just old enough to remember when "global cooling" was the enviro-scare of the day. Just like now, it was attributed to human factors: we were pouring so much crap into the atmosphere, see, it was raising the Earth's albedo and causing it to reflect more sunlight. Clearly government intervention was called for.
Fool me twice, shame on me... but what does it say when somebody gets fooled hundreds of times and comes back for more?
The USSR tried spreading soot on the winter snow to melt it and lengthen the wheat growing season.
Absolutely!
I recall reading some leftist turd's comment that the cooling effect was caused by global warming. Apparently that is the "missing link" in the evolutionary chain of scare tactics from the 60s-70s to now...
It says, "vote Democrat!"
