The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
A pair of Earth scientists, one with the University of Calgary, in Canada, the other from the University of Cambridge in the U.K., has found that studying rocks found in Duluth, Minnesota, might help us understand how Mars ...
Life on Earth began in the oceans. In the search for life on other planets, the potential for liquid water is therefore a key ingredient. To find it, scientists have traditionally looked for planets similar to our own. Yet, ...
