Here's a look at the current LabSea freeze over in 78b:

[PeterHjortLauritzen]

@adamrher Thanks!

As discussed in the CAM7 meeting, I think we will need to stop the current ECS runs although we have not reached 150 years! (this tentative decision will be discussed at tomorrows CESM projects meeting)

Reasons:

• It is highly likely that for this intermediate version of CESM3 we have shown that ECS is lower than CESM2 despite not getting to 150 years
• We will be switching to a new CESM tag in the coming weeks (answer changing!) and turn on RRTMG-P as well as possibly adopt new tunings ...

I want to confirm that the 78b series (#497, #498, and #499) had also been stopped and I had confirmed with Dave it was to stop them before stopping them.
