A new study has suggested that the disappearance of mammoths 13,000 years ago could have cooled the planet.
The study is based on the notion that mammoth flatulence would have contributed to the warming of the planet and that when mammoths started to disappear this in turn lead to a global cooling effect.
When mammoths and other Ice Age "megafauna" disappeared from the Americas about 12,800 years ago, the animals took with them their planet-warming burps—spurring the mysterious cooling period known as the Younger Dryas, a new study says.
