<!-- Turn Carbon isotopes on for clm6_0 physics with BGC on with CRUJRA or CAM7 forcing and for historical period-->
<!-- NOTE: Have Carbon isotopes off for older physics as those earlier versions were run that way.
They can only be on for BGC compsets (NOT SP or FATES).
Also, we configured the defaults the following ways:
- On only for CRUJRA2024, CRUJRA2024b, or CAM7 forcing because that is how the CESM3.0 clm6_0 simulations were run
- In contrast to above, it's turned off for other forcing options as we haven't run simulations with those configurations
- It's also only turned on for Historical periods and NOT future scenarios because we don't have CMIP7 data for them -->
