But it's not just snow we see in the results - oh no.
☔Rain is also falling at sub-zero temperatures over the ice shelves and even over the ice streams of Thwaites and Pine Island.
Rain (dark blue contours) falls above the melt line (dashed) in this figure, showing a transect through PIG.

Hi-res really helps here, and it's all we've got to go on because there are no observations of rainfall in this region - this really should change!

The slopes also drive warming near the surface, and ramp up the production of snow via a phenomenon called the seeder-feeder effect.
