Climate Change May Make Us Tiny
We know that during major climate change events,warming ocean waters cause cracks in the ocean floor to open up and release large quantities of methane gas into the air. Methane is an extremely powerful greenhouse gas, which results in even more devastating heat retention and dramatic climate change. But now it turns out that methane causes even more problems than thought.
During a great climate change event 55 million years ago, the excess of methane in the atmosphere had an unexpected side-effect. Large species–animals our size and larger–either died out or evolved into much smaller forms.
