An appeal to physicists (or the Similarly Inclined)

After being subjected to the two hours of the mindblowingly silly blonde ditzy-ness that is Legally Blonde II, my sluggish brain cells, on the verge of suicide by the end of the movie, were prodded curtly into action by a Brain Teaser. What happens to the sea level when the ice caps melt as a result of global warming? I shan't bore you to tears with my own convoluted ruminations on the topic, which have failed magnificently thus far to provide me with a satisfactory answer ("rise" or "fall"), but do feel free to share your infinitely superior knowledge.

No, economists, I will not take "it depends" for an answer.

(Unless you tell me what it depends on).

When sudden, overwhelming emotional realizations launch themselves at your sensibilities, resulting inevitably in Deep, Poignant Feelings of Utter Emptiness, such is a time for ridiculous movies, unbelievably good ice-cream, silly cartoons, side-splitting laughter-till-you-cry craziness, and an amazing girl friend with whom to undertake this endeavour with.

Throw in a side portion of profound discussions on the behaviour of ice and water molecules, complete with mathematical diagrams and lemmas, and any remaining vestiges of loneliness and sadness are either pure self-pity, or habit.
