The Basics

A few older documents (1995 & 1997) that still provide good, quick, basic overviews of the science:

• Common Questions about Climate Change.  By the United Nations Environment Programme and the World Meteorological Organization, October 1997.

• Climate Change.  State of Knowledge.  From the Environmental division, Office of Science and Technology Policy, Executive Office of the President, Washington, DC, March 1995.
