As one of the world's leading experts on climate change, Henry Pollack provides an accessible, comprehensive survey of ice as a force of nature, and the potential consequences as we face the possibility of a world without ice. "A World Without Ice" 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 lowlying regions worldwide, and the ultimate displacement of millions of coastal residents. "A World Without Ice" answers our most urgent questions about this pending crisis, laying out the necessary steps for managing the unavoidable and avoiding the unmanageable.

Ludwig’s approach includes understanding of the time period and implications of Shakespeare’s diction as well as the invaluable lessons behind his words and stories.  Colorfully incorporating the history of Shakespearean theater and society, How to Teach Your Children Shakespeare guides readers on an informed and adventurous journey through the world in which the Bard wrote.This book’s simple process allows anyone to impart to children the wisdom of plays like A Midsummer Night’s Dream, Twelfth Night, Macbeth, and Romeo and Juliet. And there’s fun to be had along the way. Shakespeare novices and experts, and readers of all ages, will each find something delightfully irresistible in How to Teach Your Children Shakespeare.
