The eventual cooling of the earth’s interior will cost us our magnetic field and our continents as they erode below sea level.
Our moon is also drifting away which causes other problems.
The Moon’s orbit increases as angular momentum is transferred from the Earth to the Moon until they become tidally locked with a period of perhaps 40 days for the Earth’s diurnal rotation and the Moon’s orbital period. Then the Sun’s angular momentum is transferred to the Moon, and the Moon’s orbit decreases until reaching the Roche limit close to the Earth. The Moon then breaksup, rains asteroidal destruction upon the surface of the Earth (already dead and barren), and the Earth acquires a ring of Moon debris in orbit around the Earth like the rings of Saturn.
