Short summary

The prognostic experiments conducted with the reference mass balance show that the grounding line would retreat by about 10 km in the three ice streams over a time period of 500 years. In the experiments, the ice flow velocities in the ice streams decreased with time. These trends in the ice flow velocities diminished the overall ice flux. The modeled evolution of the ice streams is in agreement with observations of ice mass loss in Severnaya Zemlya archipelago (Moholdt et al., 2012).
