"This is a book about ice and people--the impact of ice on Earth, its climate, and its human residents, as well as the reciprocal impact that people are now having on ice and the climate. With clarity and insight, geophysicist Henry Pollack paints a compelling portrait of the delicate geological balance between Earth and its ice, and shows why the current rapid loss of ice portends serious consequences in our not-so-distant future." -- cover.
