Global Climate Change Links

This page provides links to web pages that we at CDIAC feel do a responsible job of presenting information and discussion pertinent to the science behind the global climate change ("global warming") debate. These sites include those on both sides of the debate; some asserting that global warming is a clear and present danger, and others that might be labeled global warming "skeptics." Some of these sites don't take a position per se; they exist to offer the public objective scientific information and results on our present understanding of the climate system. The list is not intended to be comprehensive, by any means. We hope it will be especially helpful for those who may be just beginning their research into global climate change issues.

These links will take you outside of CDIAC's web server. Many will lead you to other valuable links pages. Please feel free to email Dale Kaiser at CDIAC regarding any broken links on this page, or with the addresses of quality links you think might improve this list (although we intend to keep the list manageable in size). Thank you.
