ice caps

Using my handy slide rule and easy-to-find calculations of the volume of the land-based icecaps, I came up with a 70-metre sea level rise if the Greenland and Antarctic sheets melted. I did not factor in the density of H2O in different states at various temperatures, nor did I include the...

Could anyone fill me in on the model and explanation of runaway global warming? What are the positive feedback cycles that would cause increased temperature? Ice cap loss screwing with albedo, methane release from clathrate deposits, what else? How much difference would negative feedback...
