To make a further clarification about ice caps...ice caps are dome-shaped masses of ice of < 50K sq. km. Ice sheets are >50K sq km. Ice caps and ice sheets exist in Canada, Greenland, and Antarctica. Sea ice is water from the sea that freezes. Sea ice is not the same thing as icebergs. The term "polar ice cap" can include ice caps, ice sheets, and sea ice, although technically, it is only the sea ice portion.

The northern polar ice cap = ~100% floating...

Which ones are growing?
