How Will a Warming World Impact El Niño? 5 May 2022

How Will a Warming World Impact El Niño?

ENSO is a major source of seasonal predictability and driver of global climate and extreme events. Changes in the seasonal evolution of ENSO during its onset and decay phases have received little attention by the research community. A new study published in Nature Communications aims to better understand these changes and ENSO’s impact.

NOAA’s observations help inform U.S. greenhouse gas emissions reporting for hydrofluorocarbons 25 April 2022

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.
