How to arrange global warming is a complex problem.I agree to Dave Robert's some view that we should not only action to reduce greenhouse gas even it is most important issue.
They will mostly wonder how we could not see that adding more and more greenhouse gases could only warm the Earth.
Voigt et al (2016) «Warming of subarctic tundra increases emissions of all three important greenhouse gases — carbon dioxide, methane, and nitrous oxide» The research (now reported fully bar the detailed experimenting in Voigt 2018) applies only to peatlands and concludes that N2O emissions as an issue requiring reappraisal.
Only if this is wrong, and the true value is lower, can we escape the fact that unabated emissions of greenhouse gases will lead to the warming projected by the IPCC.
The disagreement comes only over Berkeley Earth's use of a simple model fitting the temperature record for the past 250 years to human CO2 emissions and volcanoes to conclude that the best explanation for the observed warming is greenhouse gas emissions.
It would seem to be required that very drastic warming of the deep ocean is the only way that this source of Methane would be released and trigger a «runaway» greenhouse warming.

2) The committed warming: effectively the greenhouse gas increase from pre-industrial to now has committed the planet to a surface warming of 2.4 °C (using IPCCs central value for climate sensitivity), and only about 0.6 °C of this has been realized thus far.
Words only have meaning in context and while it may be true that water vapor is a greenhouse gas in the sense that more of it in the atmosphere will absorb more infrared radiation and warm the climate, it is not a greenhouse gas in the sense that it is a gas we need to seriously worry about adding directly to the atmosphere.
