Via the utterly irreplaceable Charlie Pierce, this video is spectacularly childish but also about as funny as something can be when it focuses on the upcoming destruction of human civilisation.
Some of the comments below the video are just as hilarious:
"They would take over the free world with this hoax if everyone was as gullible as their converts."
"They didn't have the consensus to back Global Cooling so they literally just changed the name."
"Would you care to explain what caused the end of the ice age and melting of glaciers? No man, no power plants, no autos, etc."
"If you reduce CO2 in the atmosphere, what will take its place? Something must and you're just hoping it is good."
Every day it becomes more clear to me that our planet is nothing but a sitcom for other, less insane sentients to watch in fits of hysterics. 'Sit down and be quiet, podlings! "Earth vs Earthlings" is about to start, and this is Sweeps Week, so they're bound to obliterate some low-lying Pacific islands at the very least!'
