For the first time, the U.S. Environmental Protection Agency (EPA) has included a comparison of NOAA’s atmospheric emission estimates of four hydrofluorocarbons (HFCs) to its own inventory-based estimates in the just-released U.S. Inventory of Greenhouse Gas Emissions and Sinks, based on results first reported in the 2017 Geophysical Research Letters study by a team of NOAA, CIRES, and EPA scientists.
Researchers have developed global forecasts that can provide up to a year's advance notice of marine heatwaves, sudden and pronounced increases in ocean temperatures that can dramatically affect ocean ecosystems.
These urban mitigation policies aimed at reducing CO2 emissions can worsen air quality and cause premature deaths if coemitted pollutants are not accounted for.
New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.
In March 2022, NOAA Climate Program Office (CPO) and NOAA Research held an interview campaign that highlighted CPO staff scientists and CPO-funded scientists for Women’s History Month.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather.
