The effects of global warming on the polar ice caps have been studied with computer models.
Background
If global warming raises the global temperature by as little as 2 degrees Celsius, the seawater will rise and melt the ice caps considerably.
Surprising Claim
But in that same scenario, the volume of the ice caps would increase.
Evaluate / Goal
Given That Rising seawater from a warmer planet would melt the ice caps considerably,
How Can We Say That The ice caps would grow in volume?
