Carbon cycle models quantify relationships between emission scenarios and resulting atmospheric concentrations, but are the projections credible? New analyses find grounds for both hope and concern.
A rare whole-lake experiment suggests that in some cases, low-oxygen conditions may have a smaller impact on methane release to the atmosphere than previously thought.
A new study provides a sample of shallow cumulus clouds simulated in domains 150-kilometers wide, enabling investigations of their structure and organization.
A new baseline of volcanic contributions to the global mercury cycle reveals how drastically human activities have increased the element’s concentration in the atmosphere.
A new textbook serves as an initial course in scientific data analysis and hypothesis testing designed for students in all science, technology, engineering, and mathematics disciplines.
Location, location, location. Surface temperature patterns play a fundamental role in Earth’s energy budget.
Amateur radio operators who study space physics and the upper atmosphere probed the ionosphere’s response to the 2023 annular solar eclipse using shortwave transmissions.
An improved representation for black carbon microphysical and optical properties alleviates overestimations of aerosol absorption efficiency in global climate models.
Minerals formed in short-lived hydrothermal systems set off by a meteor impact in France preserved information about noble gases in the ancient atmosphere.
Wildfires and soil microbes are releasing more nitrogen oxides in California as the climate gets warmer and drier.
