In his June 4 letter to the editor "Scientists Agree on Climate Change Causes," Chris Mullin makes some rather broad and seemingly profound statements regarding climate change, apparently arrived at by his reading of a book by James Hoggan. To provide perspective, it should be acknowledged that Mr. Hoggan has absolutely no scientific credentials and was "trained" by Al Gore (per Mr. Hoggan's web biography) to further pollute the climate-change debate. To purport that peer-reviewed scientific authors support, by the preposterous "score" of 928-0, the thesis that climate change is (solely) man-made reflects a serious misreading or lack of understanding of the technical literature, a tendentious summary by the author, sheer hubris by the writer or some combination of these factors.
Climate change is real. It reflects the combined effects of natural changes and an added contribution by mankind, owing largely to the burning of fossil fuels. However, despite the absurd statement that only those in bed with the oil and coal industries refute the author's claim, there are indeed many credentialed atmospheric scientists who argue, from a thorough examination of the Earth's historic record, that all climate change is not due to anthropogenic sources.
The referred scientific literature abounds with such analyses, despite the misguided allegations by Mr. Mullin. The subject is a very important one; it is not well-served by blatant misrepresentations of the facts and the historical record. If requested, I can provide hundreds of peer-reviewed citations to prove the point.
