Is groundwater heating up?
Researchers modeled groundwater temperature trends from 2000 to 2100. They estimated that groundwater could warm by up to 3.5°C over the…
A new treasure trove of Cambrian fossils
Paleontologists discovered a new set of fossils from the ancient ancestors of animals in rocks from China.
Melting glaciers release methane
Geologists studied gas fluxes from groundwater springs uncovered by melting Arctic glaciers. They estimated that these springs release over…
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
New way to find geothermal energy
Scientists used an exploration approach developed by the oil industry to track down geothermal energy sources.
Methane-munching microbes modify the seafloor
Researchers showed that methane-eating bacteria acidify their surroundings and dissolve carbonate rocks on the seafloor.
Most river water comes from the ground
Hydrologists incorporated ground and surface water flow data into Earth System models. They used these models to estimate that nearly 60% of…
Natural materials to support green energy
Scientists recycled discarded eggshells to capture rare earth elements used in green energy technology.
How did Venus’s Ishtar highlands form?
Researchers modeled tectonic and magmatic processes on Venus. They determined that its highlands formed when molten rock rose, melting its…
