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)

2017 fossil fuel CO2 emissions rising again
IEA ​ March 2018

Evidence from the top of the atmosphere to the depths of the oceans, tells an unambiguous story: the planet is warming, and this warming has been driven primarily by human activity—predominantly the burning of fossil fuels.

The rate of increase of atmospheric carbon dioxide (CO2) over the past 70 years is 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.
