What would happen if the Earth's tilt would shift to 45 deg suddenly or in a short period of time?
Would we survive?


Humans are as adaptable as rats and cockroaches. But I imagine a few
billion would die, and all our civilization and social structures
would collapse.

(It is likely that our Moon is what has kept the tilt of the Earth's
axis so stable. Mars, for instance, has seen much wider swings.)


Well, 500 years ago, earth's population was around 500 million, now 7 billion!
200 years ago , industrialization caused the exponential population growth!
Going back to 1/2 billion would be a normal thing, I think!
