Researchers have shown that over the past two thousand years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change.
Titan is Saturn's largest moon. Its cloudy appearance comes from an atmosphere mixed with gaseous nitrogen and hydrocarbons. Credit: NASA Jet Propulsion Laboratory/ Cassini Orbiter The lakes of liquid methane on Saturn's moon, Titan, are perfect for paddling but not for...
Earth has experienced five major mass extinction events over the past 500 million years. Massive volcanic eruptions have been identified as the major driver of the environmental changes that precipitated at least three of these extinction events....
A University of Wyoming researcher contributed to a paper that demonstrated, for the first time, direct observation of cloud seeding -- from the growth of the ice crystals through the processes that occur in the clouds to the eventual...
An artist's depiction of an ice-covered planet in a distant solar system resembles what the early Earth might have looked like if a mysterious mix of greenhouse gases had not warmed the climate.Credit: European Southern Observatory (ESO) For at least...
Chemical signatures recently found in rock formations are providing critical insight for understanding the formation of Earth, according to scientists. An international research team analyzed kimberlites—a type of rock formed by cooling magma that...
Stanford researchers discovered that in agricultural areas of Costa Rica, increased tree cover corresponds with increases in biodiversity. (Image credit: David Spangenburg) Scientists used tree cover maps and on-the-ground observations to measure biodiversity in Costa Rica. The results generated a...
Around four billion years ago, the Moon had a magnetic field that was about as strong as Earth's magnetic field is today. How the Moon, with a much smaller core than Earth's, could have had such a strong magnetic...
In recent decades, scientists have noted a surge in Arctic plant growth as a symptom of climate change. But without observations showing exactly when and where vegetation has bloomed as the world's coldest areas warm, it's difficult to predict...
Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to the moment ancient nomadic people first settled down and started cultivating crops. A large...
In 2019, the National Weather Service in Alaska reported spotting the first-known lightning strikes within 300 miles of the North Pole. Lightning strikes are almost unheard of above the Arctic Circle, but scientists led by researchers...
