Great Lakes ice coverage reaches historic low - NOAA Research

  2024-02-13 by in National Oceanic and Atmospheric Administration (NOAA) Research

“We’ve crossed a threshold in which we are at a historic low for ice cover for the Great Lakes as a whole,” says GLERL’s Bryan Mrockza, a physical scientist. “We have never seen ice levels this low in Mid-February on the lakes since our records began in 1973.”

Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds - Welcome to NOAA Research

  2022-05-23 (or before) in National Oceanic and Atmospheric Administration (NOAA) Research

Greenhouse gas pollution caused by  human activities trapped 49% more heat in the atmosphere in 2021 than they did in 1990, according to NOAA scientists. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of human emissions of heat-trapping gases, including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and 16 other chemicals. The AGGI converts the complex scientific computations of how much extra heat these gases capture into a...

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 - Welcome to NOAA Research

  2021-05-06 (or before) in National Oceanic and Atmospheric Administration (NOAA) Research

Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was 412.5 parts per million (ppm) in 2020, rising by 2.6 ppm during the year. The global rate of increase was the fifth-highest...
