Apparently caused by an incompatibility between matplotlib 3.3.0 and cartopy 0.17.0 -- see SciTools/cartopy#1615 . Trying to upgrade cartopy to 0.18.0 results in an unsolveable conda environment whose root cause I haven't been able to track down. Somewhere we apparently have a transitive dependency which isn't compatible with cartopy 0.18.0.
