Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there’s more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it’s vital to find ways to curb those emissions.

NATIONAL HARBOR, Md. — The U.S. Naval Research Laboratory (NRL) highlighted its latest advancements in defense technology at the Sea-Air-Space Conference and Exposition, held April 7-9, 2025, at the Gaylord National Resort & Convention Center. As the premier maritime exposition in the United States, Sea-Air-Space provided an ideal platform for NRL to demonstrate its innovative contributions to national defense.

Colder temperatures are linked with increased risk of diarrhea among Rohingya refugees in Bangladesh, emphasizing the need for climate-sensitive health strategies in refugee settings.

In a paper published in National Science Review, a Chinese team of scientists conducted an analysis on how changes in Arctic snow and ice cover affect cloud short-wave radiative effects, using satellite observations and climate model data. The study found that even under conditions where cloud properties remain unchanged, the melting of snow and ice can trigger an enhanced clouds’ short-wave cooling effect. The enhanced cooling effect can partially slow down the melting process, while it cannot reverse the overall decreasing trend of ice and snow.

The American Meteorological Society (AMS), in partnership with the National Weather Association (NWA), today released a statement regarding the proposed elimination of NOAA Research. It reads in part, "If enacted, [the administration's 2026 budget passback plan] would close all of NOAA’s weather, climate, and ocean Laboratories and Cooperative Institutes. ... In effect, the scientific backbone and workforce needed to keep weather forecasts, alerts, and warnings accurate and effective will be drastically undercut, with unknown — yet almost certainly disastrous — consequences for public safety and economic health."
