"By showing that the disappearance of the mammoths probably impacted climate, we get to an interesting if-then situation. If humans contributed to the disappearance of the mammoth, they impacted the climate in doing that," said a researcher on the study, Chris Field of the Carnegie Institution for Science in Stanford, California.
