Those are heights too…not thicknesses. Usually the 540 thickness line approximates to heights around 552, but obviously in overrunning/SWFE situations we can even go higher than that and get snow.

Typical of people to try to fix a problem by treating the symptoms rather than getting to the root of the issue. Just get the CO2 back down to where it should be. The atmosphere has the ability release excess heat out to space…trapping it in the troposphere is the problem.
