Your main point on global warming, though not stated, is that there are so many factors not taken into account by the acolytes. The end of cheap oil is upon us, so no doubt we will be more diligent in using the remaining fossil fuels more carefully and integrating them with renewables where necessary. Remember, there is coal in Antartica and other places where it would seem unusual. Various forms of nitrogen cause significant plant growth and therefore would increase CO2 uptake.
Sulfur is singularly a significant plant growth nutrient.
SOx is beneficial to plants after some conversion and some forms are directly usable for significant plant use. CO2 is so highly soluble in water than rain will wash it out very quickly. A slight increase in CO2 will dramatically increase plant growth, therefore these two simple factors may very well be excellent regulating mechanisms for atmospheric pollutants. If the globe heats up, there will be more cloud formation from oceanic higher evaporation rate and the clouds will reflect the solar input heat back into space, cooling the atmosphere. These all seem to be regulating systems which balance out each other quite well and natural systems.
