NOAA has invested in 23 small businesses developing innovative technologies in technical areas including climate adaptation and mitigation, weather-ready nation, healthy oceans, and resilient coastal communities and economies.
Multidecadal variability of Atlantic Meridional Overturning Circulation (AMOC) has been reconstructed by proxies, simulated in climate models, and linked to Arctic salinity variability. Still, some aspects of the AMOC have eluded understanding from a theoretical perspective. A new model may help.
Methane ice, or methane hydrates, represent vast reserves of natural gas, which can play a part in global carbon cycling and climate change. Methane hydrates have eerie inhabitants, and a new paper describes the worms’ microbial diversity for the first time.
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.
