The Antarctic ice sheet through the Last Glacial Cycle - numerical modelling constrained by field evidence. The response of the world's largest ice mass to climate change is important because melting leads to a rise in sea level. Our ability to predict changes in ice volume and sea level under a warming climate, will be enhanced by better understanding of past ice sheet responses to changes in atmospheric carbon dioxide.

The response of the world's largest ice mass to climate change is important because melting leads to a rise in sea level. Our ability to predict changes in ice volume and sea level under a warming climate, will be enhanced by better understanding of past ice sheet responses to changes in atmospheric carbon dioxide. Improved numerical models now exist that allow realistic simulations of Antarctic ice. These models will be developed further and constrained against existing and new field evidence for the Last Glacial Cycle (last 125,000 years), the period for which we can best define past ice sheet behaviour.Read moreRead less
Understanding the drivers and impacts of long-term Antarctic ice sheet change. This project will extend historical records of change and develop an understanding of the complex linkages between the climate and Antarctic ice sheet dynamics. The results will thereby assist in identifying the mechanisms of the past and future ice sheet stability and be communicated to the general public by enhancing scientific understanding.
