A study in National Science Review quantified “safe nitrogen boundaries” across 2,847 counties in China. It found that a cross-system management strategy could nearly halve total nitrogen pollution, bring atmospheric emissions within safe limits in most regions, and deliver benefits 2.5 times the investment required. Yet water pollution would remain above safe limits in more than half of the counties, highlighting the need for broader socioeconomic changes.

Research published in "early online" format in journals of the American Meteorological society discusses how gender affects flood mortality, U.S. ranchers and climate change, underestimations of Southern Ocean carbon uptake, terrain and tornadoes, increasing atmospheric rivers, and the future of Mississippi River water.

The American Meteorological Society has submitted an official response to the National Science Foundation’s Dear Colleague Letter about restructuring science and observing facilities associated with the National Center for Atmospheric Research, which the Trump Administration has proposed to “dismantle.”

New research published in Weather assessed the energy consumption, and therefore the carbon footprint, of AI-powered weather forecasting models.

Climate change is lengthening our days because rising sea levels slow Earth's rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length — 1.33 milliseconds per century— is unprecedented in the past 3.6 million years. The team reconstructed ancient day-length fluctuations using the fossil remains of single-celled marine organisms known as benthic foraminifera. The study has just been published in the Journal of Geophysical Research: Solid Earth.
