Abstract of Lecture
The geological record demonstrates that the level of the sea has repeatedly risen and fallen over time. There are two main mechanisms: reduction of the ocean basins by increased heatflow, which causes seawater to spill out of the ocean basin onto land of low elevation (very slow – over hundreds of thousands of years) and melting or freezing of ice sheets on continents – very fast, occurring over decades. In this talk I will look at both and examine the consequences of one, two, five, and ten meters of sea-level rise on civilization and its future agriculture, geography, and economics.
