If other events were being triggered, wouldn't CO2 levels be going down or at least staying the same? The truth is that they've been going up since the advent of the Industrial Revolution. Can you explain why? While you're at it, also explain what's happening to the energy absorbed by that CO2, given the Law of Conservation of Energy. It has to be doing something, considering that at least half of the reflected energy it absorbs should be re-emitted back towards earth.No attempt to find if such increases do or don't trigger other events that might absorb or use up more of those gases (more plants growing or oceans absorbing or whatever). Etc. etc.
