The National Oceanic and Atmospheric Administration says the levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces. Friday’s NOAA calculations show carbon dioxide, the most important and abundant of the human-caused greenhouse gases, rose in 2023 by the third highest amount in 65 years of record keeping. Scientists are also worried about the rapid rise in atmospheric levels of methane, a shorter-lived but more potent heat-trapping gas. Both jumped 5.5% over the past decade of souped-up climate change. The third biggest human-caused greenhouse gas, nitrous oxide, also spiked to a record high.
