I understood their point to be that that based on our understanding of basic physics and chemistry, the energy balance is such that the Earth system is gaining energy, and that this will lead to increased temperatures among other things. Certainly there are all kinds of complexities about how that energy will be distributed and what the effects will be, but just in terms of a simple energy balance model based on well understood physics, it would be difficult to make the case that warming won't happen.

There are lots more effects. When lots of volcanoes erupt, we also see more CO2, but we see the climate cool down.

That's because the effect of the CO2 is outweighed by other factors. But exactly that there are lots of factors is my point.

Not in the long run. If CO2 levels are increasing and the energy balance into the Earth system is positive, then the basic physics that the original poster referred to will result in warming. The net energy increase of the system will result in a higher equilibrium temperature.
