"This book sets two goals for itself: it reviews the basic cycling of elements in natural waters and the atmosphere, and documents how humans have altered these cycles. Appropriate for undergraduates with little science background, and including chapters that would fit in a first-year graduate class, this new edition of Global Environment provides a solid starting point for understanding geochemistry's role in the modern debates over global climate change."--Jess Adkins, California Institute of Technology

"This book provides a clear, up-to-date summary of geochemical processes across most areas of low-temperature geochemistry, from the point of view of key geochemical cycles. It is detailed and advanced enough to be useful for researchers while offering in-depth knowledge for advanced students."--Michael Krom, University of Leeds

"Describing water and element cycles within a global context, this newly edited and improved textbook contains valuable additional detail and information but also remains true to the strengths of its original scope."--James Bishop, University of California, Berkeley and Lawrence Berkeley National Laboratory
