The Earth rotates on an inclination of 23.5 degrees, which causes the seasons. But if the planet bowed more, up to 90 degrees, the world would be plunged into chaos. The northern hemisphere would experience a six-month winter that would devastate the ecosystem and destroy crops, then a six-month summer that would melt ice caps, raise sea levels and flood coastal cities.
