Between 1978 to1987, satellite-borne microwave radiometer data indicated that arctic ice decreased by 3. 5%, while antara ice showed no statistically significant changes. Cavalieri et al projected minimal melting the Antarctic over the next 50 years. For this reason, only the Greenland Ice Sheet is considered in the model Several models already exist for mass balance and for thermal expansion. However, these models are very complex with respect to many variables, and often disagree with each other(see for example and). We wish to develop a model based processes, as solely a function of temperature and time. In this way the analysis of the effects of the warming is simplified, and the dependence of sea level rise on temperature becomes evident. Furthermore, we develop a model that can be extended to several different temperature forcings, allowing us to compare firsthand the effect of carbon emissions on sea level riseTeam # 3694 Page 3 of 37 The density of seawater is approximately 1024.8 kg/m3 ; the mass of the Arctic sea ice is approximately 2 x 1013 kg .
