Acidifying Seas Are Wearing Away at Underwater Archaeology
Marble, limestone, and other carbonate rocks used throughout antiquity could start dissolving as oceans soak up more carbon dioxide.
COVID-19 Shutdowns Saw Human Emissions Slow, but Atmospheric Methane Surged
An uptick in wetland emissions, as well as a scarcity of atmospheric OH radicals, contributed to the counterintuitive methane spike.
Senate Committee Approves Bill to Expand NOAA Capabilities
The markup meeting, to discuss the NASA Transition Authorization Act of 2026 and the Weather Research and Forecasting Innovation Reauthorization Act of 2026, lasted less than 20 minutes.
When the Snow Melts, Microbes Bloom
A new study illuminates a complex and changing world of microbes and nitrogen cycling that occurs during the winter.
Bacteria Decide the Ocean’s Dissolved Organic Carbon Abundance
Dissolved organic carbon prevalence follows from how many bacteria are around to eat it, modeling suggests.
Antarctic Ice Sheet Has Lost a Connecticut-Sized Amount of Ice Over the Past 30 Years
A new study of Antarctica has found that since 1996, its ice sheet has lost 12,820 square kilometers (nearly 5,000 square miles) of ice—nearly enough to cover the state of Connecticut, or 10 cities the size of Greater Los Angeles.
Greenland Dust Delivers Nutrients to Ice-Melting Algae
Researchers scrutinized aerosols above and within the ice sheet, finding phosphorus and other mineral particles.
Marine Heat Waves Can Increase Coastal Rainfall
Unusually warm ocean waters can amplify extreme rainfall in downwind areas, leaving coastal communities—especially those in developing countries—at risk.
Understanding Aerosol-Cloud Interactions is Pivotal for Improving Climate Predictions
Global cooperation and knowledge sharing are essential to improve our understanding of cloud formation and evolution through aerosol-cloud interaction.
