NOAA Report Finds 2021 GHGs Trapped 49% More Heat Than 1990
NOAA Report Finds 2021 GHGs Trapped 49% More Heat Than 1990
NOAA’s Annual Greenhouse Gas Index (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 single number that can easily be compared to previous years and tracks the rate of change. NOAA scientists released the first AGGI in 2006 as a way to help policymakers, educators, and the public understand the cumulative impact of greenhouse gases on climate over time.
