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…
Microbes make different greenhouse gases during wetland drainage
Researchers found that soil microbes release less methane but more carbon dioxide and nitrous oxide in draining peatlands.
How complex plants reshaped the oceans
Researchers found that when complex plants evolved, they increased ocean oxygen and massively restructured the marine ecosystem.
Rising soil temperatures could stop forests spreading
Researchers found higher soil surface temperatures prevented seedling survival and forest expansion in low-elevation forests.
Geologists identify a new way copper ore forms
Researchers found that massive copper ore deposits in central Arizona formed from melted crust rather than melted mantle.
City waste could support urban farming
Researchers found that adding city waste products to local farms promoted a healthy soil microbiome and improved how tomatoes taste.
Global warming could impact bumblebees’ senses
Researchers showed that rising temperatures make it harder for bumblebees to detect their sugary food sources.
