Large-scale reforestation could lead to slight reduction in global warming

Planting new forests could contribute more to the mitigation of climate change than previously thought, according to a new study in Geophysical Research Letters.

Dormant volcano near Rome is waking up

A long-dormant volcano outside Italy’s capital is entering a new eruptive cycle, finds a new study in Geophysical Research Letters.

Climate tipping points: What do they mean for society?

In a new study in Earth’s Future, scientists lay out strategy for investigating societal consequences.

Future astronauts might not be able to use water on Mars, study suggests

Last year, scientists made a splash with the news that dark streaks on the Martian surface were signs of flowing liquid water. So far, they have been unable to determine where the water is coming from, but a new study in the Journal of Geophysical Research: Planets eliminates some of the possibilities.

How do the deep waters of the Antarctic form?

In a new study in the Journal of Geophysical Research: Oceans, researchers uncover new insights into the life cycle of water in the Antarctic region by measuring noble gas concentrations.

Carbon dioxide frost may keep Martian soil dusty

Temperature readings acquired from orbit show that Mars’s surface gets cold enough at night to allow layers of solid carbon dioxide frost up to several hundred micrometers thick to build up near the equator, finds a new study in the Journal of Geophysical Research: Planets.

A new tool to better forecast volcanic unrest

In a retrospective study of volcanic unrest at Indonesia’s Kawah Ijen, a new model published in Geochemistry, Geophysics, Geosystems was able to pick up on the rising probability of eruption 2 months before authorities were aware of the risk.
