Ice flow, fractures, and damage
Ice sheet models assume a flow law for solid ice. However, damaged/crevassed ice may will effectively be less viscous than undamaged ice. We need a better way to handle this in ice flow models.

Ice streams and ice sheet sensitivity
Ice streams can display oscillatory and even chaotic behaviour. How does the state of ice streams influence the predictability of the ice sheet response to anthropogenic forcing?
