Anthropogenic Greenhouse Gas Emissions
 |
Global anthropogenic emissions of Greenhouse gases (CO2, CH4, N2O and F-gases) continue to be emitted at an annual rate that is not yet significantly decreasing. The global warming potential of each of the greenhouse gases and their long residence time in the atmosphere are causing increased surface temperature and climate change. The scientific community illustrated with inverse models and data assimilation how consistent the reported inventories and the atmospheric observations are, which is taken up also in few national inventory reports (e.g. UK, Switzerland, Australia). |

(*) Goal (G): an ideal requirement above which further improvements are not necessary. Breakthrough (B): an intermediate level between threshold and goal which, if achieved, would result in a significant improvement for the targeted application. The breakthrough value may also indicate the level at which specified uses within climate monitoring become possible. It may be appropriate to have different breakthrough values for different uses. Threshold (T): the minimum requirement to be met to ensure that data are useful.
