This new booklet, compiled by some of the finest climate scientists and economists, undermines this comfortable conceit. Stressing anew the total uncertainty of climate change science, the authors challenge the key antinomy at the heart of Kyoto – namely that climate is one of the most complex systems known, yet we claim we can manage it by trying to control a small set of factors, namely greenhouse gas emissions. The dangers of such a viewpoint for public policy are made abundantly apparent.
