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!


I'm all for a reduction of the human population back down to a billion
or less. But ideally by attrition, not cataclysm. And the whole
collapse of civilization thing would be nice to avoid!

(This is likely to happen in any case, but by our own making, not some
mysterious adjustment of Earth's axis.)

Today's high tech , consumption based economies rely on massive populations to sell more goods!
