Uncertainty Abounds in Seeding the Sky to Fight Climate Change
Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
Thunderquakes Map the Subsurface
Researchers have figured out how rumbling thunder turns to seismic waves and how this shaking could be used to reveal subsurface geology.
Mapping Mars: Deep Learning Could Help Identify Jezero Crater Landing Site
Researchers used new techniques to more precisely estimate ground elevations on Mars, producing a refined resolution map for rover landings.
Carbon Dioxide’s Effect on Mountain Climate Systems
Greenhouse gases are rising in the atmosphere. But how will precipitation patterns change as climate systems rise over mountain chains?
How Wildfires and Weather Affect Portugal’s Public Health
Researchers dug into data to examine the effects of wildfires, pollutants, and meteorological factors on mortality and cardiovascular health in the Iberian country.
How You Make Money Matters When It Comes to Carbon Emissions
Investment income is associated with more carbon emissions in the United States.
Optimizing Carbonate Classification on Mars
Combining data from several of the Perseverance rover’s spectroscopic sensors offers a more accurate means to classify carbonate minerals that may hold hints of ancient life.
When It’s Too Hot for Fans
Electric fans keep vulnerable people cool in a warming world. But new research shows there are increasing numbers of hours when—and places where—using fans may be dangerous.
Mapping Beaver Dams with Machine Learning
A new model deploys a neural network to spot beavers’ engineering exploits in aerial and satellite imagery, an approach that should aid studies of ecosystem and landscape change.
