A University of Massachusetts Amherst-led research team has discovered that weaker rock in mountain landscapes erodes three times faster than harder rock—even on gentler slopes—and is one of the main attributes governing mountain erosion. The finding also challenges our current understanding of the relationship between erosion and the release of carbon dioxide, and suggests that geologists and atmospheric scientists may be underestimating the CO₂ contributions coming from the Earth's rocky places.

Scientists discover a hidden 100-million-year-old volcanic system

Scientists have uncovered a long-lost volcanic system in Iran that dates back roughly 100 million years, revealing a hidden chapter in Earth's tectonic history. The discovery sheds new light on the disappearance of an ancient ocean and the powerful geological forces that reshaped

A decade of carbon dioxide data from space gets an upgrade

Every day, two NASA space instruments known as the Orbiting Carbon Observatory-2 and -3 (OCO-2 and OCO-3) capture more than a million observations of sunlight reflecting off Earth's surface. Using the physics of how light travels through the air, an algorithm converts these raw d
