Models have overestimated atmospheric levels of hydroxyl radicals, which break down methane. A new discovery shows that water vapor reduces sunlight's availability to make hydroxyl radicals, slowing methane’s atmospheric breakdown rate.
Researchers long thought the Deep Western Boundary Current was the main pathway for deep water movement in the North Atlantic. A new study identifies another significant route, the Eastern Pathway east of the Mid-Atlantic Ridge.
Drought is one of the costliest and deadliest climate-related disasters in the United States. NOAA’s National Integrated Drought Information System and the University of Nebraska Medical Center have led the development of the first comprehensive assessment of drought and health.

The CPO-led National Integrated Drought Information System (NIDIS), has launched a redesigned U.S. Drought Portal to better serve stakeholders, decisionmakers, the media, and the public.
NOAA-funded scientists found that warmer than normal ocean temperatures, rather than air temperatures, cause periods of rapid ice sheet calving known as Heinrich events. For decades, Heinrich events…
Combustion-related emissions (from motor vehicles) have historically dominated urban-center pollution. But recent air-quality research shows that those emissions are falling while non-combustion-related emissions (from solvents, paints, and hygiene products) are rising. A new field campaign in the Greater New York City Metropolitan Area aims to gather real-time data.
A special issue of the open access journal Earth System Science Data showcases results and datasets from a month-long field campaign in Barbados in 2020.
A new fire emissions inventory, providing publicly available data on trace gases and aerosols from global fires for the years 2002 through 2021, add improvements to previous inventory.
