More information


The global concentration and forcing from different greenhouse gases and other agents have been taken from literature/data sources. They have been added by using Radiative forcing (see methodology section), and that back to ppm CO2e by the the forcing of CO2.


ppm CO2e (parts per million CO2 equivalent)
