Mars' Emitted Energy and Seasonal Energy Imbalance

Seasonal imbalance between the solar energy absorbed and released by the planet Mars could be a cause of the Red Planet's dust storms, according to new research. Understanding how the system ...

Hunga Volcano Eruption Provides an Explosion of Data

The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also ...

More Difficult Than Expected for Glaciers to Recover from Climate Warming

Ice shelves are floating extensions of glaciers. If Greenland's second largest ice shelf breaks up, it may not recover unless Earth's future climate cools ...

Newly Discovered Lake May Hold Secret to Antarctic Ice Sheet's Rise and Fall

Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might answer questions about what Antarctica was like ...

Ice-Capped Volcanoes Slower to Erupt, Study Finds

The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- ...

Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for ...

Failed Eruptions Are at the Origin of Copper Deposits

Copper is one of the most widely used metals on the planet today due to its electrical and thermal conduction properties. The greatest natural resources of this metal are the so-called ...

Major 2020 Alaska Quake Triggered Neighboring 2021 Temblor

A study of two powerful earthquakes in adjacent areas off the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade ...

Landslides Can Have a Major Impact on Glacier Melt and Movement

Using satellite imagery to study the effects of a 2019 landslide on the Amalia Glacier in Patagonia, a research team found the landslide helped stabilize the glacier and caused it to grow by about ...

Carbon, Climate Change and Ocean Anoxia in an Ancient Icehouse World

A new study describes a period of rapid global climate change in an ice-capped world much like the present -- but 304 million years ago. Within about 300,000 years, atmospheric carbon dioxide levels ...
