A new study adds to evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that forms lakes and rivers under the ice sheet. Although the heat source isn't a new or increasing…
Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of…
Using hundreds of satellite radar images the team, working with Geomatic Ventures Limited (GVL), an innovative University spin-out company, created a complete map of mainland Scotland. The map covers a two-year period from 2015 to 2017 and was created using…
East Asian summer monsoon (EASM) is one of the most dominant climate systems in East Asia. The anomalous EASM can cause extremely high temperatures, floods or drought. And the El Niño-Southern Oscillation (ENSO), the dominating mode in the tropical Pacific,…
Long Valley, California, has long defined the "super-eruption." About 765 000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 km3 (182 mi3) of lava and ash spewed out in the kind of volcanic cataclysm we hope never…
Researchers from several European institutions found that northern high-latitude cooling played a role in triggering the rapid termination of the African Humid Period 5500 years ago. It is one of the driest regions of the Earth, yet, in a cave in the Egyptian…
500 000 people in Latin America and the Caribbean are at high risk from coastal hazards, according to a new study by researchers at UC Santa Cruz and the University of Cantabria, Spain. The catastrophic 2017 hurricane season provided ample demonstrations of the…
The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the…
A tsunami that struck Hawaii in 2011 and caused a temporary halt to boat traffic has provided scientists a rare glimpse into what the bays might sound like without human activities. The tsunami, triggered by the same earthquake that caused the Fukushima nuclear…
Astronomer Gregory Rudnick sees the universe crisscrossed by something like an interstellar superhighway system. Filaments — the strands of aggregated matter that stretch millions of light years across the universe to connect galaxy clusters — are the…
