About 56 million years ago, volcanoes quickly dumped massive amounts of carbon dioxide into the atmosphere, heating the Earth rapidly. This time period — called the Paleocene-Eocene Thermal Maximum, or PETM — is often used as a historic parallel for our own future under climate change, since humans have also rapidly poured carbon dioxide into … Read more
