Glaciers & Ice Caps: The Melting
The question, according to interviewed experts in this survey of ice cap melting, is how much and how fast ice caps are melting, not if melting will occur. Scientists in the Arctic and Antarctica show how the world's great ice sheets and polar caps are disappearing, while computer graphics help illustrate concepts, demonstrating how overall warming is affecting ocean levels, movement of currents, and ice caps. Scholars explain that thawing of the permafrost releases additional trapped carbon, which speeds up melting. This cycle continues accelerating and seems unstoppable. An experiment using mounds of ice melting on asphalt illustrates how glaciers shift as they melt.. this title makes the topic most accessible for students.
