An annual assessment released Monday by a U.S. agency underscored the need to dramatically cut planet-warming pollution with a notable revelation about heat-trapping gases over the past three decades.<\/p>\n
Greenhouse gas (GHG) pollution from human activities trapped 49% more heat in the atmosphere in 2021 than in 1990, according to<\/a> the National Oceanic and Atmospheric Administration (NOAA).<\/p>\n NOAA announced that finding in its update of the Annual Greenhouse Gas Index (AGGI), which converts the warming influence of carbon dioxide \u2014 or CO2, the most common GHG \u2014 as well as methane, nitrous oxide, chlorofluorocarbons, and 16 other chemicals into one number that can be compared to previous years, as the agency explained in a statement.<\/p>\n “The AGGI tells us the rate at which we are driving global warming,” said Ariel Stein, acting director of NOAA’s Global Monitoring Laboratory (GML).<\/p>\n “Our measurements show the primary gases responsible for climate change continue rising rapidly, even as the damage caused by climate change becomes more and more clear,” she added. “The scientific conclusion that humans are responsible for their increase is irrefutable.”<\/p>\n NOAA’s yearly update of the Annual Greenhouse Gas Index, or AGGI, is out. Our actions and emissions are heating our planet. https:\/\/t.co\/OKFmerqR85<\/a><\/p>\n \u2014 NOAA Climate.gov (@NOAAClimate) May 23, 2022<\/a><\/p><\/blockquote>\n\n
