Natural gas leaks are a significant source of methane emissions in cities, but it can be hard to pinpoint exactly where and why they happen. And methane, a potent greenhouse gas that is the main chemical component of natural gas, has been historically undercounted or omitted in emissions estimates, according to a team of atmospheric and climate science researchers in the Penn State College of Earth and Mineral Sciences.

How life on Earth experiences climate change
Climate change can look very different at the scale of a forest, field or hillside. A new review shows how changes in vegetation and atmospheric conditions can cause local microclimates to warm at very different rates from the regional climate—and why this matters for understandi

A massive asteroid slammed into the North Sea and unleashed a 330-foot tsunami
A decades-long mystery beneath the North Sea has finally been solved. Scientists have confirmed that the Silverpit Crater, buried 700 meters below the seabed, was created when a 160-meter-wide asteroid struck Earth roughly 43 to 46 million years ago. The violent collision blasted
