What is a good Q factor?
What will the world look like in 1 billion years?
What will the world look like in 1 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 […]
