Extinctions during the early Triassic period left Earth a virtual wasteland, largely because life literally couldn’t take the heat, a new study suggests.
Between 247 to 252 million years ago, Earth was reeling from a mass extinction called the end-Permian event. The die-off had wiped out most life on Earth, including most land plants. The planet was baking, and life at the Equator struggled to survive.
Plants gobble up carbon dioxide, which warms the planet. So without them, Earth became like a runaway greenhouse, it started to get out of control.
