The rate of mass loss from the Greenland Ice Sheet (GrIS) has tripled over the last 20 years, reflecting strong climate warming over the region. Here I will present a review of some of the Greenland mass-balance evaluations that I have been involved with over the last 15 years. We will also review other recent estimates of GrIS mass change, including some very recent observational updates from satellite data, noting the impacts on global sea-level rise. I will then focus on some current key challenges in modelling the meteorologically-driven surface mass balance component (SMB = snow accumulation minus surface melt-water runoff), and highlight what future work is needed to address remaining gaps in our knowledge and understanding of GrIS mass balance changes and climate interactions.

The guest lecture is held in connection with the RISES Strategic projects under Bjerknes Centre for Climate Research, Bergen, Norway.
