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.

I thought draining Lake Agasiz due to failure of ice dams caused the Younger Dryas event. I gotta stop getting science fron Al Gore.

Burps? I heard it was the other end. Is NatGeo getting prissy?
