Climate Debate Daily is intended to deepen our understanding of disputes over climate change and the human contribution to it. The site links to scientific articles, news stories, economic studies, polemics, historical articles, PR releases, editorials, feature commentaries, and blog entries. The main column on the left includes arguments and evidence generally in support of the IPCC position on the reality of signficant anthropogenic global warming. The right-hand column includes material skeptical of the IPCC position and the notion that anthropogenic global warming represents a genuine threat to humanity.

Many sites on the Internet, including some of those listed at the far left of the page, take firm views for or against the threat of anthropogenic global warming. As a matter of editorial policy, Climate Debate Daily maintains a studied neutrality, allowing each side to present its most powerful and persuasive case. Our object is to allow readers to form their own judgments based on the best available information.

Climate Debate Daily offers new material at the tops of its main columns six days a week. Many links, especially those to news periodicals, have limited shelf life, and we urge readers to save or print out contributions they regard as important. Although links are eventually transferred to our Archive pages, we retain no copies of material linked to here.

Items removed from Climate Debate Daily last year can be found in our 2008 Archive. Items trimmed off the page so far in 2009 can be found in our 2009 Archive.

Douglas Campbell is currently completing a Ph.D in philosophy at the University of Arizona while teaching philosophy at the University of Canterbury in New Zealand. He has degrees in computer science and biology, and has worked as a wildlife ranger with endangered species. His areas of philosophical expertise include logic and the philosophy of science. He is impressed by the breadth and depth of the scientific evidence supporting the theory of anthropogenic global warming, and thinks that to the extent that the science remains uncertain the Precautionary Principle still justifies even relatively costly mitigation measures. Like Prof. Dutton, he is, however, open to being led by logic and good evidence to whatever the truth may be. His optimistic hope is that Climate Debate Daily will help focus minds on the very best arguments from both sides of the debate and help put the poor arguments (of which there are many!) to rest.

Denis Dutton is Professor of Philosophy at the University of Canterbury in New Zealand. He founded and edits the Johns Hopkins University Press journal, Philosophy and Literature, and the well-known website, Arts & Letters Daily. At the University of Canterbury he has introduced a new course on the distinction between science and pseudoscience. Prof. Dutton is skeptical about the degree to which human activity has contributed to the general warming trend that began in the 1880s. He adds, however, "Working at the university where Karl Popper taught in the 1930s and 40s, I am more than a little aware of the way that good scientific hypotheses must always be open to falsification. The best way for science and public policy to proceed is to keep assessing evidence pro and con for anthropogenic global warming. That is the idea behind Climate Debate Daily." Denis Dutton's personal website is here.

Climate Debate Daily is an independent website which began its life on the internet on January 1, 2008. It has no financial or institutional connection with the University of Canterbury, Arts & Letters Daily, or Philosophy and Literature. Climate Debate Daily is generously supported by a grant from Dr. Peter Farrell of ResMed Corp. (www.resmed.com). Like Denis Dutton, Dr. Farrell is skeptical of the threat of anthropogenic global warming. But he also says, "Let the best argument win."
