Well, one year ago today was the day a chill was cast on the subject of man made global warming, with the release on the Internet of a collection of e-mails and documents that became known as "Climategate".
Even before then, the view among scientists and the public was far from the "consensus" portrayed by much of the Media. A couple of good sources of information are Climate Debate Daily, which features articles from proponents and skeptics, and Climate Depot, a site with a definitely skeptical point of view which culls many articles from various sources.
As I've said before, climate science is a complex field that certainly merits vigorous research and monitoring, but is far from being "settled" so as to justify drastic upheavals to economic and social policy. National, security, economic growth and general environmental stewardship are all good reasons to be more efficient in use of resources and to develop new energy sources, but those can be done in a way consistent with respecting life and liberty.
