This book is a collection of 15 lectures presented at a summer school session, “Remote Sensing and Long-term Global Datasets for Climate Studies,” held at Dundee University, August 2–13, 1999. The lectures, each of which is covered in a chapter, have been revised and updated. Thus,they provide a nice balance between understanding and modeling global climate change while presenting the potential that remote sensing data sets have for observing global climate. Since global change has been in the media quite frequently lately with the recent Senate committee hearings, this book serves as an excellent resource. From it, readers can glean a better understanding of where the United States and other nations stand in terms of global climate change issues.
