The book _The Environmental Record in Glaciers and Ice Sheets_ edited by Hans Oeschger and C. C. Langway, Jr., is a comprehensive overview of the environmental information stored in polar ice sheets. It serves as a valuable resource for non-specialized readers, providing insights into how ice sheets record and preserve environmental data. The book is based on the Dahlem Workshop held in Berlin in March 1988, which addressed four key issues: how glaciers record environmental processes, the anthropogenic impacts recorded in glaciers, the establishment of ice core chronologies, and the long-term implications of the ice core record for global environmental changes. The volume includes background papers and summary group reports, offering both a general review and novel ideas, such as the gravitational separation of atmospheric gases in ice. It highlights the interdisciplinary nature of the field, linking glaciology with concerns like acid rain, heavy metal pollution, and the Greenhouse effect. Overall, the book is well-structured and provides thought-provoking content for scientists and students interested in the environmental record over the past few hundred thousand years.The book _The Environmental Record in Glaciers and Ice Sheets_ edited by Hans Oeschger and C.
