Fact of the day! One possible scenario of how life could end here on Earth. Clathrate Explosion One of the scariest threats to life on Earth lies deep below the sea, just waiting for a little warmth to free it and kill us all. Methane clathrate is a form of water ice that exists in vast amounts on the ocean floor. This ice contains a large amount of the greenhouse gas methane. As global temperatures increase, these clathrates are swelling, and when it gets warm enough the methane frozen inside them will explode, sending gas, ash and smoke up through the ocean in enormous geysers. These explosions could trigger a cascade of more clathrate release, finally sending our ecosystem over the tipping point to extinction.
