Global Warming is a seven-volume set that describes the most critical issues concerning this timely subject and explains in up-to-date detail the scientific principles involved. Each volume reviews the cause-and-effect relationships that impact the environment worldwide on daily, annual, and even longer time bases. Designed to complement science curricula, the books cover the spectrum of important climatic issues, helping the reader to build a solid foundation of knowledge with which to approach important topics related to global warming.

Global Warming Cycles: Ice Ages and Glacial Retreat focuses on the mechanisms that triggered past climate changes that repeatedly put Earth in and out of ice ages. The book compares "natural" cycles with today's global warming and presents the many physical factors that shape the Earth's climate. The book looks at how climatologists use landform clues from the past to assess global warming and how they apply that knowledge to help prepare current and future society for what is to come. Citing actual examples and multinational statistics, figures, and case studies, sidebars in the book enhance fundamental concepts and give the reader a sense of the urgency and enormity of the issue.

The volume includes information on

abrupt changes in climate

climate research

the cryosphere and isotasy

glacial retreat

hurricans and global warming

ice ages

ocean currents and climate

rising sea levels

tornado and thunderstorm research

water resources and global warming

The book contains more than 40 color photographs and line illustrations, sidebars, a chronology, an appendix of global warming information sites, a glossary, a detailedlist of print and Internet resources, and an index. Global Warming is essential for high school students, teachers, and general readers who wish to learn about important climatic issues and their impact on the environment and society worldwide.
