What will life be like in a billion years?

In about one billion years, the solar luminosity will be 10\% higher than at present. This will cause the atmosphere to become a “moist greenhouse”, resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end, and with them the entire carbon cycle.

How long have humans been in the Americas?
