Few scientists doubt the prediction that the antropogenic release of carbon dioxide in the atmosphere will lead to some warming of the earth's climate. So there is good reason to investigate the possible effects of such a warming, in dependence of geographical and social economic setting. Many bodies, governmental or not, have organized meetings and issued reports in which the carbon dioxide problem is defined, reviewed, and possible threats assessed. The rate at which such reports are produced still increases. However, while more and more people are getting involved in the 'carbon dioxide business', the number of investigators working on the basic problems grows, in our view, too slowly. Many fundamental questions are still not answered in a satisfactory way, and the carbon dioxide building rests on a few thin pillars. One such fundamental question concerns the change in sea level associated with a climatic warming of a few degrees. A number of processes can be listed that could all lead to changes of the order of tens of centimeters (e. g. thermal expansion, change in mass balance of glaciers and ice sheets). But the picture of the carbon dioxide problem has frequently be made more dramatic by suggesting that the West Antarctic Ice Sheet is unstable, implying a certain probability of a 5 m higher sea-level stand within a few centuries.

Presents calculations of how sea levels around the world would change if the west Antarctic ice sheet melted. Shows that rise would not be uniform everywhere. Calculations are reversible, should ice sheet subsequently accumulate.

The Last Interglacial (116 ka - 130 ka) is the most recent time when Earth's climate was as warm or warmer than it is today. It therefore may make a suitable proxy for understanding the impacts of modern climate change. One such impact of immediate relevance to the modern world is that of sea level rise. Global sea level is currently rising at an accelerating pace, threatening lives and economies around the world. Notably, evidence from paleoclimate data suggests global sea level during the Last Interglacial was at least 6.6 m higher than present sea level and perhaps more than 8 m higher. As the Earth adjusts to the rapid onset of modern climate change, we may expect sea level to approach that of the Last Interglacial. Noticeable changes in sea level have a number of sources, including melting glaciers, ice sheets, and ocean thermal expansion. The Antarctic Ice Sheet has been inferred to be the largest contributor to Last Interglacial sea level change, adding between 4.1 and 5.8 m to global sea level during that time. Most of this change is expected to come from the West Antarctic Ice Sheet, which is thought to be prone to marine ice sheet instability. However, uncertain basal boundary conditions and ocean forcing make it a challenge to know how the ice sheet may have lost such a large amount of mass. In this work, I seek to better constrain mass balance and sea level contributions of the Antarctic Ice Sheet during the Last Interglacial and explore evidence from inside the ice sheet itself which may reveal if and how the ice sheet sustained such a large mass balance change during the Last Interglacial. To do so, I use a transient ice sheet model to simulate reconfiguration of the Antarctic Ice Sheet under Last Interglacial conditions and find a stable configuration consistent with estimates of Antarctic contributions to Last Interglacial sea level. I then analyze englacial radar stratigraphy to study the ice dynamics by dating a series of isochronous englacial reflectors which have been mapped through the central West Antarctic Ice Sheet. For comparison to this data, I implement a steady state ice sheet model to simulate englacial isochronous surfaces with various uncertain model boundary conditions.

Climate modelling is a field in rapid development, and the fltudy of cryospheric processes has become an important part of it. On smaller time scales, the effect of snow cover and sea ice on the atmospheric circulation is of concern for long-range weather forecasting. Thinking in decades or centuries, the effect of a C02 climatic warming on the present-day ice sheets, and the resulting changes in global sea level, has drawn a lot of attention. In particular, the dynamics of marine ice sheets (ice sheets on a bed that would be below sea level after removal of ice and full isostatic rebound) is a subject of continuous research. This interest stems from the fact that the West Antarctic Ice Sheet is a marine ice sheet which, according to some workers, may be close to a complete collapse. The Pleistocene ice ages, or glacial cycles, are best characterized by total ice volume on earth, indicating that on 4 5 large time scales (10 to 10 yr) ice sheets are a dominant component of the climate system. The enormous amount of paleoclimatic information obtained from deep-sea sediments in the last few decades has led to a complete revival of iriterest in the physical aspects of the Pleistocene climatic evolution.
