Passage Summary: Computer models suggest that global warming will melt the polar ice, but surprisingly, the total amount of ice will still get bigger.

Reasoning: Models indicate that a small temperature increase would cause significant melting of the polar ice caps, yet the same models predict the total volume of those ice caps would actually increase.

Analysis: The paradox here is the tension between 'melting' and 'increasing volume,' which seems counterintuitive at first glance. To resolve this, we need a piece of information that explains how the ice caps could gain more mass than they lose to melting. For instance, if warmer temperatures lead to significantly increased snowfall in polar regions, the accumulation of new ice could outpace the loss from melting. Look for an answer that provides a mechanism for ice growth that compensates for the heat-induced melting.
