There’s an interesting line in the book “Lucifer’s Hammer”. The astronauts are circling the earth, discussing how we’re probably entering a new ice age versus global warming.
One astronaut says the pollution and heat pollution are probably the only reason we aren’t in an ice age then, when the other says “But we’re running out of oil!”
Their main objective is to get the nuclear plant online and connected to the grid? I’ve been thinking about that recently.
