Why is it hard to predict the future of ice sheets?

Ice sheet retreat, hypotheses of instability could be missing important processes that limit the rate or extent of retreat, or conversely, Ice sheet behavior is strongly influenced by processes at its margin and base. Observations of rapid changes at these boundaries are helping modelers to improve...

Description
Summary:Ice sheet retreat, hypotheses of instability could be missing important processes that limit the rate or extent of retreat, or conversely, Ice sheet behavior is strongly influenced by processes at its margin and base. Observations of rapid changes at these boundaries are helping modelers to improve predictions of future changes.
