CAM6 Climate sensitivity

We are trying to undertsand the difference between the climate sensivitity in CESM1 and CESM2.

125 had a climate sensivity similar to CESM1.
CESM2 has a much larger climate sensitivity. In the 4xCO experiments, it seems that the behavior changes sometimes between 125 and 202.

In the following we revert some of the features between 125 and 202. The experiments are done with cesm2.0 tag (this is the 297)
