Visiting Professor Skeptical On Global Warming

This evening, Professor Aynsley Kellow, Head of the School of Government at the University of Tasmania, gave an Open Lecture on "The Environmental Debate: Climate Change in the 21st Century". He was returning as a graduate of Otago University, and has published a book on this subject.
Professor Kellow expressed concern at the politicization and extremism of the Global Warming proponents, and pointed out much evidence which raises doubts about the theory. Skepticism should be the proper attitude of Science, and not used as an insulting term.
Several "Greenies' in the audience walked out, showing their intolerance of differing viewpoints.
I think that the tide is turning on the Global Warming debate. There is also a skeptical article in this week's student magazine, "Critic", something unlikely to have happened in the past.
As global temperatures fail to increase as predicted, the theory is becoming increasingly in doubt.
