Models show that a rise in global temperatures would melt the ice caps considerably, but the models also preduct that the ice caps would increase in total volume.
The correct answer will be a hypothesis that explains how something that considerably melts the polar ice caps can also increase their volume. This explanation must result in the ice caps' growth outweighing their shrinkage from melting, and provide some mechanism for how this growth occurs.
