A clear-eyed explanation of the impact of ice on Earth, its climate, and its residents.   Much has been written about global warming, but the crucial relationship between people and ice has received little focus, until now – and there is a fierce urgency as the problem accelerates. With clarity and insight, geophysicist and a co-winner of the 2007 Nobel Peace Prize, 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.   Whether sculpting mountains, regulating temperatures, influencing ocean currents, or defining the limits of human settlement, ice has shaped – and continues to shape – the world we live in. This important and increasingly relevant book traces the effect of mountain glaciers on supplies of drinking water and agricultural irrigation, as well as the current results of melting permafrost and shrinking Arctic sea ice – a situation that has degraded the habitat of numerous animals and sparked an international race for seabed oil and minerals. Catastrophic possibilities loom, including rising sea levels and subsequent flooding of low-lying regions worldwide.   A World Without Ice explains why ice matters, and lays out the urgent actions we can take to restore Earth’s delicate climate balance.
