• Monthly temperature
• Monthly precipitation
Step 2: Extrapolation of model
parameters to all glaciers in
Iceland and Scandinavia
• Gridded climate variables
Step 3: Future projections until
2100 for each glacier:
- run mass-balance model
- Volume-area scaling

Figure 1. Scenario building for AWM in Horsens Fjord
To estimate of the adaptation strategy (Table 2) we will use back-casting approach. The assessments
of the productivity of this approach are based on main big strategies which need to have an attention.
