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.

Additional information
The figure covers the world-wide observed concentration.
Data expressed in CO2-equivalents (see CSI013 justification for explanation). Note that the trend in the figure is much shorter with respect to the one for Kyoto gases, due to the unavailability of long-term data for aerosols and ozone.
