Gotcha, I see. You're not wrong that a combination of scientific illiteracy and political orthodoxy can give terrible outcomes. So some default skepticism is quite wise.
If you want to understand the effect of the trace gases from first principles, you can read more about it under "Effective temperature of the Earth" at https://en.m.wikipedia.org/wiki/Stefan%E2%80%93Boltzmann_law . It also links to the Wikipedia page about the greenhouse effect, which you'll appreciate more after reading about the Stefan Boltzmann law first.
OK, will read, much appreciated. Just have to deal with my fence that blew down in the high winds we had in the UK yesterday - climate change no doubt (joke). Thank you.
