The radiative heat forcing of  today's atmospheric GHGs (above) commits the world to a global warming of 1.5C by 2030-2040 (IPCC AR5 WG1 Figure 11.6)  and full equilibrium warming of 2.0C.

'The current RF(radiative forcing) from GHGs maintained indefinitely (i.e., the commitment from constant greenhouse gas concentrations) would correspond to approximately 2°C warming.'  ​(IPCC AR5 WG1

UK MET Office March 2017 The reviewed 2015 atmospheric CO2 increase was 3.39 ppm. With no El Nino the 2017 forecast is 2.46 ppm still much higher than the 10 yr average of 2.1 ppm/yr
