 Already committed  ​future warming  ​
 and climate change

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 12.5.4.2)

Accelerating atmospheric CO2 at a 3-5 million year high, has been  increasing at a rate over "the past 70 years of nearly 100 times larger than that at the end of the last ice age ... such abrupt changes in the atmospheric levels of CO2 have never before been seen".
