Fifty-five million years ago, Earth’s thermostat shot up—and life dramatically changed. Here’s what history can teach us about our modern temperature surge.
Previous periods of rapid warming millions of years ago drastically altered plants and forests on Earth. Now, scientists see the beginnings of a more sudden, disruptive rearrangement of the world's flora.
Researchers have managed to simulate the climate during the Paleocene-Eocene Thermal Maximum - when Earth was 14 degrees Celsius warmer than it is now.
Decades of research have demonstrated that human activities, primarily the emission of carbon dioxide from the combustion of fossil fuels, are driving climate change.
