      Haha. It has nothing to do with global warming. Humans will be long gone by then(800 million years). By 600 million years, the Sun’s increasing luminosity begins to disrupt the carbonate–silicate cycle; higher luminosity increases weathering of surface rocks, which traps carbon dioxide in the ground as carbonate. As water evaporates from the Earth’s surface, rocks harden, causing plate tectonics to slow and eventually stop. Without volcanoes to recycle carbon into the Earth’s atmosphere, carbon dioxide levels begin to fall. By 800 million years, CO2 levels fall to the point that no photosynthesis will be possible.
