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 can be found in our 2008 Archive, our 2009 Archive, our 2010 Archive, our 2011 Archive, our 2012 Archive, our 2013 Archive, our 2014 Archive and in our 2015 Archive.

We welcome reader suggestions for links to include on Climate Debate Daily. Please send them here. On questions of what ultimately goes onto the page, the editors' decisions are final.

The editors are keen to be informed when readers notice errors or dud links on the page. Please let us know here.

Patrick Whittle is completing a PhD in political philosophy at the University of Canterbury in New Zealand. His research into the social and political implications of Darwinian theory touches upon many disciplines, including anthropology, biology, human history and pre-history, economics and psychology, as well as social and political theory. (His latest paper, "Health, Inequality and the Politics of Genes", in the New Zealand Medical Journal, indicates the range of his academic interests.) Before returning to academia, initially gaining a Masters degree in linguistics, Patrick was an officer in the New Zealand Army. He has lived and worked as a teacher in the Middle East, and as a newspaper journalist and a sub-editor in New Zealand. Patrick accepts that there is solid evidence for anthropogenic global warming, but is skeptical of many of the political proposals for remedying its possible impact. While he is a keen mountain runner and a passionate cycle commuter, Patrick does acknowledge that there is a place in the world for cars. It's called the garage!

Douglas Campbell has a PhD in philosophy from the University of Arizona and is a lecturer in 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 in New Zealand. 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 Patrick Whittle 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.

Climate Debate Daily is an independent website which began its life on the internet on January 1, 2008. It came into being after Doug Campbell and the University of Canterbury's Professor Denis Dutton had a spirited but friendly argument about climate change in the philosophy department's tea room, which resulted in a decision to set up a site dedicated to fairly presenting both sides of the issue. Professor Dutton, who was skeptical about the degree to which human activity has contributed to the general warming trend that began in the 1880s, remained an active editor of Climate Debate Daily until late 2010. Climate Debate Daily has no financial or institutional connection with the University of Canterbury. It is generously supported by a grant from Dr. Peter Farrell of ResMed Corp. (www.resmed.com). Dr. Farrell is skeptical of the threat of anthropogenic global warming. But he also says, "Let the best argument win."
