Coal ash, red mud, and mine tailings are usually treated as major waste problems. Yet these enormous waste streams also contain valuable materials, including silica, rare earth elements, and other critical minerals. A research team led by Worcester Polytechnic Institute (WPI) has received a $3.3 million award from the National Science Foundation’s Growing Convergence Research […]

Arctic sea ice does not always move the way wind alone would predict. New research led by UC Riverside suggests that a simple but overlooked process may help explain the difference: individual pieces of ice repeatedly collide with one another. The findings could eventually help scientists improve forecasts of how sea ice moves across the […]

A powerful eruption at Indonesia’s Anak Krakatau sent ash high into the atmosphere, disrupting thousands of flights and worsening air quality across parts of the country. Anak Krakatau is a small but highly active volcano located between the Indonesian islands of Java and Sumatra. Its eruptions are often relatively modest, but the volcano is also […]

New research from Colorado State University suggests that irrigating U.S. crops may deliver a surprisingly large climate benefit by allowing farmers to produce more food without converting additional natural land into agriculture. Irrigation increases crop yields, which means the same amount of food can be grown on a smaller area. According to the researchers, if […]

When Hunga Tonga-Hunga Ha’apai erupted beneath the South Pacific in January 2022, the explosion ranked among the most powerful volcanic events of the modern era. But researchers have now uncovered an unexpected consequence of that eruption: the enormous volcanic cloud appears to have helped destroy some of the methane pollution produced by the volcano itself.
