The Tutorial consists of 8 Lessons which are best read in order. They are intended as a very basic introduction to climate science.  No background in the physical sciences is required and they are written for high school students, college students and adults. Questions about any of this material can be sent to Ray.Climate (@ sign) charter.net and they will be responded to in the Q&A page of this website.

The Essays consist of material I am contributing which provides some background to how scientists carry out their research, but does not deal with the scientific content itself.

The Tutorial material is based upon  my reading of peer-reviewed papers in the climate science literature as well as personal visits and email exchanges I have had with many leading researchers. I am in the process of editing these Lessons in order to provide the source material on which most of these Lessons are based. This information will be found at the end of each of the Lessons.

I express my sincere thanks to the many Climate Scientists who have provided references and copies of their papers and who have answered my questions about their work. I would especially like to acknowledge Dr. Christopher Castro, Department of Atmospheric Sciences, University of Arizona; Dr. Ken Caldeira, Department of Global Ecology, Carnegie Sciences; and Drs. Lisa Sloan and Mark Snyder, Department of Earth and Planetary Sciences, U.C. Santa Cruz for generously providing PowerPoint presentations from which many of the figures in this Tutorial were taken.
