NOAA Annual Greenhouse Gas Index
This visualization of the NOAA Annual Greenhouse Gas Index shows the relative warming contribution from various greenhouse gasses (1979-2022). The donut chart shows 2022 AGGI data.
The NOAA Annual Greenhouse Gas Index (AGGI) tracks the increasing amount of heat being added to the atmosphere by human-related greenhouse gas (GHG) emissions. It is based on the highest quality measurements of GHGs in the atmosphere from sites around the world.
This visualization contains data from 1979-2022. The quantity plotted is the global radiative forcing, which is a measure of how much each component is warming the Earth. The 'other' category includes hydrofluorocarbons (HFCs), Chlorofluorocarbons (CFCs), and hydrochlorofluorocarbons (HCFCs). The donut chart shows the 2022 data.
This visualization, aimed at showing the relative contributions of each gas, leaves off the scale and units. In 2022 the total radiative forcing was 3.4 Watts per meter squared.
