Where does fossil fuel C end up, and how does that change with changing parameters?

Cosmetic stuff

Reorder sources facet figure from high to low?
Start tracking figures at 1800 to not show tracking artifacts?
Haewon: make figure 5 wide, not tall?

Analysis changes to consider

Steve: constrain with historical ocean heat uptake/content and/or temperature?
Haewon: maybe use an extreme one to tell the storyline? Steve: careful about 8.5
Trevor: careful about beta - we haven't seen 2x CO2
Kalyn: LUC emissions - are they varying?
Kalyn: Could we calibrate Hector specifically for this study?
With Kalyn we realized that NO 'calibrated Hector' won't help us vis-à-vis observational record

Potential discussion notes

Turnover / carbon cycling - why soil contribution is so much higher to atmosphere fraction (vegetation cycles faster back and forth)
Steve: secular trend (increase) in ocean in figure 5?
Trevor: note this comment on van Marle et al.: https://arxiv.org/abs/2204.11651

For the future (not this study)

Trevor: two-pool soil model?

Calibration

Option 1 - use what we're using for parameters; use CMIP6 for history/future and CO2/tas - a run has to pass all four criteria to qualify
Option 2 - we could calibrate Hector to observational record; that's fine and produces good performance
Option 3 - model constraint

We're saying Option 1.

Ocean heat diffusivity?
