Yes, I did read it. It is a guest column on some "free press" site written by Tom Harris who is a "mechanical engineer and Ottawa Director of High Park Group, a public affairs and public policy company". Spin doctors are not exactly know for balanced, fair views, but for propagating what their clients pay them for. The article is a collection of the typical lone voices, many of them retired professors, who have a dissenting view. They do not reflect the common view among climatologists. When trying to find a more balanced view, I turn to renowned scientific journals such as Science, not to something a spin doctor collected. This should be obvious, should it not?
Here's what Science says:
The scientific consensus is clearly expressed in the reports of the Intergovernmental Panel on Climate Change (IPCC). Created in 1988 by the World Meteorological Organization and the United Nations Environmental Programme, IPCC's purpose is to evaluate the state of climate science as a basis for informed policy action, primarily on the basis of peer-reviewed and published scientific literature (3). In its most recent assessment, IPCC states unequivocally that the consensus of scientific opinion is that Earth's climate is being affected by human activities: "Human activities ... are modifying the concentration of atmospheric constituents ... that absorb or scatter radiant energy. ... [M]ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations" [p. 21 in (4)].
IPCC is not alone in its conclusions. In recent years, all major scientific bodies in the United States whose members' expertise bears directly on the matter have issued similar statements. For example, the National Academy of Sciences report, Climate Change Science: An Analysis of Some Key Questions, begins: "Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise" [p. 1 in (5)]. The report explicitly asks whether the IPCC assessment is a fair summary of professional scientific thinking, and answers yes: "The IPCC's conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue" [p. 3 in (5)].
Others agree. The American Meteorological Society (6), the American Geophysical Union (7), and the American Association for the Advancement of Science (AAAS) all have issued statements in recent years concluding that the evidence for human modification of climate is compelling (8). http://www.sciencemag.org/cgi/conten.../306/5702/1686
But what does the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science (AAAS) count, when ATM disagrees based on thin air, or a spin doctor manages to collect a few dissenting voices?
