The number of years within which the peak concentration levels could be exceeded are indicated by the purple arrows, given the trend in total greenhouse gas concentrations over the past 10 years (based on IPCC, 2018)

Methodology:
The figure is complied using the observed concentration levels and the observed trend over the past 10 years as a starting point. IPCC 2013 and IPCC 2018 provided information on the peak and 2100 concentration levels consistent with keeping the global average temperature increase below 1.5 °C (left) and 2 °C (right), for various probability levels of achieving these temperature targets (from top to bottom). The higher the probability level the lower the peak and 2100 concentration has to be.
