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)
