Climate in Human Perspective

A tribute to Helmut E. Landsberg

The editors intend that this book conveys the remarkable variety and fundamental importance of the late Helmut E. Landsberg's many contributions to the science of climatology and its practice over a very productive 55-year career. We thank the distinguished authors for their contributions. We also thank Corinne Preston and Charlene Mann for their invaluable word-processing assistance and preparation of camera-ready copy. Finally, we thank Joshua Holland for permission to reproduce his portrait of Landsberg, and Jeanne Moody for preparation of the index. F. Baer N. L. Canfield J. M.
