This is the first book to present the science and instruments of NASA’S MESSENGER space mission. The articles, written by the experts in each area of the MESSENGER mission, describe the mission, spacecraft, scientific objectives, and payload. The book is of interest to all potential users of the data returned by the mission, to those studying the nature of Mercury, and by all those interested in the design and implementation of planetary exploration missions.

Water is fundamental to all life. From the Dust Bowl of the 1930s, to the extreme water shortages that have struck California in recent years, modern societies often take its abundance for granted until it unexpectedly becomes scarce. Drought is one of the many problems anthropogenic climate change may exacerbate, but it is also a complex phenomenon at the intersection of a range of scientific disciplines and public policy issues. In this innovative book, Benjamin I. Cook brings together climate science, hydrology, and ecology to provide a synthetic overview of drought and its environmental and social consequences. Cook introduces readers to the hydroclimate and its components, explaining the global water cycle, the earth’s climate system, and the distribution of water resources. He discusses drought dynamics and variability over time, the climatological context and ecological effects, and environmental issues such as desertification, land degradation, and groundwater depletion. He also considers the socioeconomic impacts of drought and the role of drought risk management policy, especially in light of how climate change is expected to affect drought risk and severity. Cook gives special attention to paleoclimate and the role of drought in the crises of ancient civilizations. A scientifically comprehensive and approachable overview of water issues throughout the world, Drought is a critical interdisciplinary text that will be essential reading for a broad range of students in earth science and environmental and sustainability studies.
