What will Earth be like in 1 billion years?
In about one billion years, the solar luminosity will be 10% higher, causing the atmosphere to become a “moist greenhouse”, resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics and the entire carbon cycle will end.

How long do humans have left?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
