According to the report, “the global annual average atmospheric carbon dioxide concentration was 414.7 parts per million (ppm) … which was 2.3 ppm greater than 2020 amounts and was the highest in both the modern 63-year record as well as the highest in the last million years.” Scientists also observed respective records for methane and nitrous oxide concentrations. These three gases comprise the major atmospheric greenhouse gas concentrations that contribute to global warming.
