Eruption Now Unlikely Near Icelandic Town
Scientists and local authorities had been tracking the eruption’s precursors for weeks and evacuated residents. Then the magma stalled.
Spacecraft Are Sprinkling the Stratosphere with Metal
Metals from spacecraft reentry don’t simply vaporize and vanish. Scientists found them in the stratosphere.
Temperature Extremes Hit Lower- and Middle-Income Countries Hardest
Smaller cities in these regions are less likely to have infrastructure to deal with extreme climates.
Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
Landfast Sea Ice: The Most Important Ice You’ve Never Heard Of
Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.
More Than Half the World’s Ocean Surface Is Getting Greener
Advances in data analysis help researchers spot shifting ocean colors, which could be associated with climate change.
Using Bayesian Estimation to Improve Methane Inventories
A Bayesian, optimal estimation evaluation of state-of-the-art methane inventory with satellite-based emissions from 2009 to 2018 finds substantial differences for livestock, rice, and coal emissions.
Precisely Synced Clocks Pave the Way for New Science
Researchers working on Hawaiian mountain tops precisely synchronized two clocks with unprecedented efficiency, demonstrating the potential to create networks of such clocks for geodesy and more.
Lightning-Caused Wildfires are 80 Percent More Likely Under Dry Vegetation
Mimicking a randomized control trial of wildfires, scientists use satellites to uncover the key role of vegetation dryness in wildfire risk, aiding wildfire management and preparedness in California.
