Correct, however for those who do the maths, energy captured due to CO2 absorption (all else ignored) has a T^3 factor. Blackbody radiation (the heat emitted to space) has a T^4 component. When you do the maths, temperature rise is logrithmic with CO2 proportion. Basically, temperature rise is quoted for a doubling in CO2. Say 1.2 degrees - to get another 1.2 degrees, you need to double again etc.
Now to try to make it scarier, you can introduce feedback - so the hotter it gets, the rate of increase get faster to offset the logrithmic CO2/T. The trouble is that whilst the temperature increase due to CO2 has been tested time and again, and uses sound physics principles, the feedback is more or less guess work. Models are tweaked with new feedback terms until they match previous years...
You were doing so well then you just sailed right off the tracks. On what basis do you claim that feedback is more or less guesswork? Models are not tweaked to match previous years. Any adjustments are made on the basis of better understanding of the physics involved.
