Mountain glaciers and ice caps will melt and locally disappear due to climate warming. Projecting the impact on sea level rise, water resources and the living world requires an inventory of the current volume and distribution of glacier ice on earth. My PhD project aims to provide this information by using novel inverse modelling algorithms which yield ice thickness maps (and thus ice volume) for all >200000 glaciers in the world. After developing the methodology last year, this year will focus on applications. To start with, all glaciers in Scandinavia will be modelled. At a later stage, the method will be refined and upscaled to all glaciers in the world.
