The current warming of the Earth is leading to important social questions being raised: How warm will the Earth become and when? What effect will it have on human life? Should we try to slow down these trends? If so, how do we do this while balancing the economic needs of society? Global Climate Change and Human Life attempts to answer some of these questions, providing facts and theories that will help the reader formulate rational opinions and gain a new way to think about the complexities of the subject and the future of the global environment and climate. Divided into three parts, this book covers the composition of the atmosphere, the workings of the earth's climate and how the changing global climate will affect the environment and how that will affect human life. Featuring numerous questions and exercises and worked examples throughout the text, this book is intended for undergraduate students taking courses in global climate change. Based on a course that the author has given to students from a number of subject disciplines the book will appeal to all needing a well-written, unified introduction to the subject.

An important purpose of The Handbook of Environmental Chemistry is to aid the understanding of distribution and chemical reaction processes which occur in the environment. Volume 4, Part B of this series is dedicated to Air Pollution Control Equipment, Materials Damage, Peroxyacyl Nitrates, Semivolatile Compounds in the Atmosphere, and Arctic Haze.

Methane plays many important roles in the earth's environment. It is a potent "greenhouse gas" that warms the earth; controls the oxidizing capacity of the atmosphere (OH) indirectly affecting the cycles and abundances of many atmospheric trace gases; provides water vapor to the stratosphere; scavenges chlorine atoms from the stratosphere, terminating the catalytic ozone destruction by chlorine atoms, including the chlorine released from the man-made chlorofluorocarbons; produces ozone, CO, and CO2 in the troposphere; and it is an index of life on earth and so is present in greater quantities during warm interglacial epochs and dwindles to low levels during the cold of ice ages. By all measures, methane is the second only to CO2 in causing future global warming. The book presents a comprehensive account of the current understanding of atmospheric methane, and it is an end point for summarizing more than a decade of intensive research on the global sources, sinks, concentrations, and environmental role of methane.
