Presented by Ben Marzeion, Institute of Meteorology and Geophysics, University of Innsbruck, Austria, at the ESA-CliC Earth Observation and Arctic Science Priorities Meeting, Norway, 2015

In this presentation, we will review recent estimates of the mass change of glaciers and ice caps (GICs). On the global scale, methodological advances and better data availability have lead to a reconciliation of mass loss estimates for the recent past. These estimates include the results of models that are used to reconstruct century-scale mass change of GICs based on climate records and glacier length changes, thus increasing the confidence in these long-term estimates. There is also good agreement between different models used for projecting future GIC mass change on the global scale.

However, on the regional scale, great differences become apparent between different methods for reconstruction, and different models for projections. These inconsistencies are particularly pronounced in the Arctic. We will identify the likely error sources, and infer improvements that can be realized by (i) better data coverage, (ii) better usage of existing data, and (iii) better modeling strategies.

The atmosphere-ocean boundary layer in which sea ice resides includes many complex processes that require a more realistic treatment in GCMs, particularly as models move toward full earth system descriptions. The primary purpose of the workshop was to define and discuss such coupled processes...
