Atmospheric concentration of Nitrous Oxide (ppb) Atmospheric concentration of Nitrous Oxide (ppb) The figure shows the global atmospheric concentration of nitrous oxide up to 2010.
Atmospheric concentration of Methane (ppb) Atmospheric concentration of Methane (ppb) The figure shows the global atmospheric concentration of methane up to 2010.
Contribution of the different GHGs to the overall greenhouse gas concentration in 1950, 1990 and 2010 Contribution of the different GHGs to the overall greenhouse gas concentration in 1950, 1990 and 2010 Contribution of the different GHGs as included in the Kyoto and Montreal protocol to the overall greenhouse gas concentration in 1950, 1990 and 2010.
Observed trends in total global greenhouse concentrations, considering all greenhouse gases (incl. aerosols) for 1970-2010 Observed trends in total global greenhouse concentrations, considering all greenhouse gases (incl. aerosols) for 1970-2010 The figure shows the total global concentration of Kyoto protocol Gases (KPG), gases under the Montreal Protocol (MPG) and non-protocol related gases (NPG). NPGs contribute negatively, as they have an overall cooling effect, whereas the other gases contribute positively. The threshold concentration range is based on a 50% probability of exceeding 2 degree Celsius temperature increase, given different models and scenarios.
Observed trends in total global concentration of the Kyoto gases, 1850-2010 Observed trends in total global concentration of the Kyoto gases, 1850-2010 Data expressed in CO2-equivalent (see CSI013 justification for explanation). The threshold concentration range is based on a 50% probability of exceeding 2 degree Celsius temperature increase, given different models and scenarios.
