 Already committed  ​future warming  ​and climate change

The radiative heat forcing of  today's atmospheric GHGs commits the world to a global warming of 1.5C by 2030-2040 (IPCC AR5 WG1 Figure 11.6)  and full equilibrium warming over 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 12.5.4.2)
