a part of the problem is likely the changes in subgrid topography in
Greenland. Here is a snippet from an email from Julio to the CESM
"126 with enhanced surface roughness around Greenland could be colder in
the Labrador sea. Marcus L. has seen cooling there in our F2000 cases.
Let's see what it does to Lab sea ice."
My understanding is that the Lab Sea is still behaving fairly well in the
B-case they are currently running. Note, however, that this assessment is
only based on a few decades worth of data so it could change in a longer
