When thinking about drought and heatwaves, it is natural to focus on the western contiguous United States. But an ongoing drought has also struck the Northeast. A new study examines how climate change may affect droughts in that region.
An international team has collected a high-resolution bathymetric and hydrothermal plume survey of the post-eruption caldera. Employing an uncrewed surface vessel, the survey was conducted by scientists and engineers across the globe.
In 2022, mid-latitude ozone-depleting gases fell halfway back to their 1980 levels. The reduction marks a major milestone because ozone depletion was not significant prior to 1980.
Black carbon, or soot, affects climate as well as human health. A new study shows the results of using machine learning to to improve black carbon prediction and ultimately replace traditional models for predicting black carbon.
The Western Water Assessment has just released a dashboard to complement the recently published Utah Hazard Planning Tool. The dashboard provides resources about the historical incidence, current risk, and future projections of natural hazards in Utah.
Aerosols—microscopic solid or liquid particles suspended in air—significantly affect the Earth’s weather, air quality, and climate. NOAA has just released an updated factsheet on aerosols and climate.
Hurricane Andrew made landfall near Homestead, Florida, on August 24, 1992. NOAA scientists recount the powerful hurricane and the progress in hurricane research over the last 30 years.
Climate models forecast declines in Mediterranean winter precipitation, thanks to a weakened Atlantic Meridional Overturning Circulation. Simulations suggest the Mediterranean may dry even with substantial reductions in greenhouse gas emissions after 2040.
A new study investigates wildfire contributions to atmospheric nitrous acid in the western United States. The study finds that direct emissions from wildfire smoke are not the only—or even the most important—source of nitrous acid.
Atmospheric rivers generate most of the economic losses associated with flooding in the western United States. A new3 study find these damages could increase by over a billion dollars by the 2090s.
