Mean atmospheric greenhouse gases July 2020 CO2 414.38 ppm CH4 1880 ppb N2O 332 ppb
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". WMO Oct 2017
