"Even when discussing a subject which seems capable of objective treatment, one can scarcely expect to escape charges of writing with political bias. These charges have now taken on such ingenious forms that they are hard to refute. No longer is the primitive objection made, that a statement is contrary to the truth; it is old-fashioned to say that an opponent is mistaken, though subjectively honest. Nowaday's the opponent's point of view is accepted as a point of view, but is dismissed on the grounds that the person concerned is not in a position to argue objectively by reason of his belonging to a certain social class, or because he has grown up in a certain milieu."

(If you see the connection, you might also like this quote:
"Karl Marx omitted to discuss the question of how the socialist state would work in practice, and [he] kept others from doing so. Those of his disciples who went into the question were derided and stamped as "unscientific", the most awful malediction to which members of "the scientific school" could be exposed." (p. 4))

Climate Audit is run by my coauthor Steve McIntyre. He works at trying to verify the results in published paleoclimatic papers, and much of the blog documents his attempts to get the data and methodology. Which turns out to be surprisingly difficult.

Climate Science is excellent-quality commentary by atmospheric scientist Roger Pielke Sr. Visit daily.

The Science and Public Policy Institute among other things features the work of Christopher Monckton, Viscount of Brenchley, who has emerged as a skilled and determined opponent of climate alarmism. Be sure to check out his movie, which presents his recent lecture at Cambridge. I think that if Churchill were still around he would walk past a roomful of MPs to shake Monckton's hand.

CO2Science is an on-line library put together by two Arizona-based plant biologists. You can search the scientific literature on any climate-change related topic and find ample contrarion research. They provide the citations and summaries of the study and results. There is especially detailed information about the effects of climate change on plants. They also publish editorials each week.

The Friends of Science . A group of sensible people out west have begun to do what Environment Canada ought to have done long ago--compile some on-line information so that people can read up on some unsettled issues on this interesting topic.

The Competitive Enterprise Institue. This small think tank in Washington runs on a shoestring, yet has had a huge impact on international climate policy.

Real Climate. Set up by Michael Mann and Gavin Schmidt, it presents the orthodox take on climate science. Papers of interest are usually discussed here and at Climate Audit simultaneously so it's worth comparing approaches.

Government of Canada Climate Change Web Site Hope you enjoy it--you paid for it. See what a billion dollars will buy you. It reports on all the deep thinking in Ottawa concerning climate change.

The David Suzuki Foundation. Canada's tireless environmental gadfly has been warning about the imminent dangers of climate change for over a decade. This is one of the prettiest web sites on the Internet--it must have cost a fortune.

The Worldwatch Institute. They have published an annual State of the World report for decades, and generally are worried about a lot of things, including climate change.

The Heat is On. Based on a book by journalist Ross Gelbspan this site exposes the vast international conspiracy by big industry to destroy the planet and make fun of the author.

Global Warming: Early Warning Signs. Sponsored by a host of green groups this map digs up evidence of global warming, or at least of warm weather, in literally tens of places around the world. It also shows where global warming has caused precipitation to increase, except for the places where global warming has caused precipitation to decrease.

The Intergovernmental Panel on Climate Change . Oops, can't forget the folks who got the game started.
