How could two teams of scientists come to such obviously contradictory conclusions on seemingly every point that matters in the debate over global warming? There are many reasons why scientists disagree, the subject, by the way, of an excellent book a couple years ago titled Wrong by David H. Freedman. A big reason is IPCC is producing what academics call "post-normal science" while NIPCC is producing old-fashioned "real science.

The scientists Heartland works with demanded we host a ninth conference this year to foster a much-needed frank, honest, and open discussion of the current state of climate science and we just couldn't refuse. The public, the press, and the scientific community will all benefit from learning about the latest research and observational data that indicate climate science is anything but 'settled.

The benefits of a modest warming would outweigh the costs - by $8.4 billion a year in 1990 dollars by the year 2060, according to Robert Mendelsohn at Yale University - thanks to longer growing seasons, more wood fiber production, lower construction costs, lower mortality rates, and lower rates of morbidity (illness).

The IPCC - and all the mainstream media and environmental extremists who cite it uncritically - really have become a joke in the scientific community.
