That Time It Rained for Two Million Years
Climate change is nothing new. The Earth's weather has gone through different periods of hot, cold, dry, and wet over its lifetime. Nearly 234 million years ago, the planet went through one of these stages. At the time, the world was one big supercontinent known as Pangea. The entire surface was flat and extremely dry. That is, until one day it started raining, and it kept on raining for the next two million years.
