A prediction for 1.1 billion years in the future:

> The Sun's luminosity has risen by 10%, causing Earth's surface temperatures to reach an average of c. 320 K (47 °C; 116 °F). The atmosphere will become a "moist greenhouse", resulting in a runaway evaporation of the oceans.[65][70] This would cause plate tectonics to stop completely, if not already stopped before this time.[71]

Would somebody be able to ELI5 the connection the Earth's average temperature and plate tectonics?

Not a geologist, but I rember reading something about this a while back, so this might be BS. I believe it's because the water being pulled down at the subduction zones (where one plate gets forced down under another) help lubricate the whole process. I think that without that water I think the mantel becomes too stiff.
