The Climates of Earth’s Next Supercontinent: Effects of Tectonics, Rotation Rate, and Insolation
Abstract We explore two possible Earth climate scenarios, 200 and 250 million years into the future, using projections of the evolution of plate tectonics, solar luminosity, and rotation rate. In one scenario, a supercontinent forms at low latitudes, whereas in the other it forms at high northern la...
