Carbon dioxide released from thawing permafrost may have contributed to major global warming events about 55 million years ago, suggests a new study published in the journal Nature. The study suggests that carbon released from thawing permafrost could explain the ancient warming event known as the Paleocene-Eocene Thermal Maximum (PETM) and a series of smaller warming events that followed, between 55 and 52 million years ago.
