IPCC list of greenhouse gases

rdf:langString IPCC list of greenhouse gases

rdf:langString This is a list of the most influential long-lived, well-mixed greenhouse gases, along with their tropospheric concentrations and direct radiative forcings, as identified by the Intergovernmental Panel on Climate Change (IPCC). Abundances of these trace gases are regularly measured by atmospheric scientists from samples collected throughout the world. Since the 1980s, their forcing contributions (relative to year 1750) are also estimated with high accuracy using IPCC-recommended expressions derived from radiative transfer models. This list excludes: * water vapor which is responsible overall for about half of all atmospheric gas forcing. Water vapor and clouds are more dynamic atmospheric constituents and contribute strong climate change feedback influences. * other short-lived gases (e.g. carbon monoxide, NOx) and aerosols (e.g. mineral dust, black carbon) that also vary more strongly over location and time. Ozone has warming influences comparable to nitrous oxide and CFCs, and is longer lived and more abundant in the stratosphere than in the troposphere. * many refrigerants and other halogenated gases that have been mass-produced in smaller quantities. Most are long-lived and well-mixed. Some are also listed in Appendix 8A of the 2013 IPCC Assessment Report. and Annex III of the 2021 IPCC WG1 Report * oxygen, nitrogen, argon, and other gases that are less influenced by human activity and interact relatively little with Earth's thermal radiation.
