NOAA’s observations help inform U.S. greenhouse gas emissions reporting for hydrofluorocarbons

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.

New Global Forecasts of Marine Heatwaves Foretell Ecological and Economic Impacts 20 April 2022

New Global Forecasts of Marine Heatwaves Foretell Ecological and Economic Impacts

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.

Climate mitigation policies for cities must consider air quality impacts 14 April 2022

Climate mitigation policies for cities must consider air quality impacts

These urban mitigation policies aimed at reducing CO2 emissions can worsen air quality and cause premature deaths if coemitted pollutants are not accounted for.

Solid aerosols in Arctic atmosphere could impact cloud formation and climate 14 April 2022

Solid aerosols in Arctic atmosphere could impact cloud formation and climate

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.
