The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater—one of many circular depressions in the landscape left ...
At one of the world's largest emission fields of non-volcanic carbon dioxide in southern Italy, researchers have detected a complex variety of seismic tremor signals, captured by a seismic array deployed in the region in ...
Volcanoes draw plenty of attention when they erupt. But new research led by the University of Washington shows that volcanoes leak a surprisingly high amount of their atmosphere- and climate-changing gases in their quiet ...
Earth is about 29% land and 71% oceans. How significant is that mix for habitability? What does it tell us about exoplanet habitability?
For hundreds of millions of years, Earth's climate has warmed and cooled with natural fluctuations in the level of carbon dioxide (CO₂) in the atmosphere. Over the past century, humans have pushed CO₂ levels to their ...
As the scientific community searches for worlds orbiting nearby stars that could potentially harbor life, new Southwest Research Institute-led research suggests that younger rocky exoplanets are more likely to support temperate, ...
Severe environmental crises led to a series of large-scale extinction events in the Jurassic period 178-186 million years (myr) ago. The turmoil has been ascribed to the abundant release of volcanic gases, but the temporal ...
Thirty years ago, on the flanks of a volcano in California's Sierra Nevada range, trees began to die en masse, suffocated at their roots by carbon dioxide seeping up from the mountain's depths after a swarm of small earthquakes.
Around the world, between 40 and 50 volcanoes are currently erupting or in states of unrest, and hundreds of millions of people are at risk of hazards posed by these potentially active volcanos. Yet, despite the profound ...
The rapid development of fauna 540 million years ago has permanently changed the Earth—deep into its lower mantle. A team led by ETH researcher Andrea Giuliani found traces of this development in rocks from this zone.
