Team 3694 Page 4 of 37 Model overview a deeper understanding of ice sheet melting would provide valuable insight into sea level rise. By creating a framework that incorporates the contributions of ice sheet melting and hermal expansion, we can estimate global mean sea level over a 50-year time period The model achieves several important objectives 1) Accurately fits past sea level rise data 2) Provide enough generality to predict sea level rise over a 50-year span 3)Compute sea level increases for Florida as a function of solely global temperature and time Ultimately, the model predicts consequences to human populations. In particular, we analyze the impact of sea level rise on the state of Florida, which many conside particularly vulnerable due to its generally low elevation and proximity to the Atlantic Ocean. From this analysis, we assess possible strategies to minimize damage as a result of sea level rise due to global warming Assumptions In order to streamline our model we have made several key assumptions 1) The sea level rise is primarily due to two factors, the balance of accumulation/ablation of the greenland Ice Sheet and the thermal expansion of the ocean. This ignores the contribution of processes such as calving and direct human intervention, which are difficult to model accurately and have minimal effect on sea level rise 2) The air is the only heat source for melting the ice. Greenland's land is permafrost, and because of large amounts of ice on its surface it is assumed at a relatively constant temperature. This allows us to use convection as a mode of heat transferTeam # 3694 Page 4 of 37 Model Overview A deeper understanding of ice sheet melting would provide valuable insight into sea level rise.
