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.
