Abstract

Results of modeling the flow and temperature within the ice showed that the critical thicknesses need to produce shear-heating instability and catastrophic surging are not much larger than the present value of the thickness of the Antarctic ice dome. The waxing and waning of ice sheets redistributes mass on the Earth's surface and as a result causes changes in both the geographical location of the rotation pole and the length of the day. Such trends in the motion of the rotation pole can have a profound influence on the future course of ice ages. -from Current Antarctic Literature
