|a Despite major recent efforts, marine ice sheet models
aiming at predicting future mass loss from ice sheets still
suffer from uncertainties with respect to grounding line
migration. A recent model intercomparison provided tools
to test how models treat grounding line dynamics in a
three-dimensional setting. Here we use these tools to address
to what extent differences in mass loss occur according
to the approximation to the Stokes equations, describing
marine ice sheet flow, used. We find that models that
neglect components of vertical shearing in the force budget
wrongly estimate ice sheet mass loss by ˙50% over century
time scales when compared to models that solve the full
Stokes system of equations. Models that only include
horizontal stresses also misrepresent velocities and ice shelf
geometry, suggesting that interactions between the grounded
ice sheet and the ocean will also be modeled incorrectly.
Based on these findings, we strongly advise the use of
high-order models to compute reliable projections of ice
sheet contribution to sea level rise. |
