To read what is published by most of the popular media, which have jumped on the Global Warming bandwagon almost en masse, one would likely conclude that the matter is settled -- indeed, that is presently the chief claim intended to squelch all argument on the matter. Hardly a day goes by that one interested in the question doesn't hear claims that practically all scientists agree that Global Warming is upon us and that mankind's technological overreach, especially in adding CO2 to the atmosphere, is the primary cause. (And we are seldom reminded of the fact that climate change, often of far greater magnitudes than anything human beings have seen, has been taking place throughout not only all of human history but virtually all of Earth history -- which goes back not mere millions but billions of years before the first humans trod the Earth.)
Lawrence Solomon of Canada's National Post newspaper ably puts the present-day picture into perspective; he focuses on several dozen top-tier scientists in relevant fields from around the world and very readably describes their reasons for doubt on these matters, and never forgets to summarize the scientific facts behind them. While I myself don't yet have a copy of the book, I've essentially read all of it online during the course of last year on the National Post website, in which a new article appeared every week or two. Though Solomon at first set out to write only a few articles on a handful of these "deniers," the more he looked the more world-class research scientists he discovered among their ranks, and somewhat to his own surprise found these were hardly a fringe element but on the contrary at or near the pinnacles of their professions worldwide -- notwithstanding being virtually ignored by much of the media and, importantly, by the United Nations' Intergovernmental Panel on Climate Change (IPCC). But let Solomon speak on this in his own words:
"More than six months ago, I began writing this series, The Deniers. When I began, I accepted the prevailing view that scientists overwhelmingly believe that climate change threatens the planet. I doubted only claims that the dissenters were either kooks on the margins of science or sell-outs in the pockets of the oil companies.
"My series set out to profile the dissenters -- those who deny that the science is settled on climate change -- and to have their views heard. To demonstrate that dissent is credible, I chose high-ranking scientists at the world's premier scientific establishments. I considered stopping after writing six profiles, thinking I had made my point, but continued the series due to feedback from readers. I next planned to stop writing after 10 profiles, then 12, but the feedback increased. Now, after profiling more than 20 deniers [38 at last count], I do not know when I will stop -- the list of distinguished scientists who question the IPCC grows daily, as does the number of emails I receive, many from scientists who express gratitude for my series.
"Somewhere along the way, I stopped believing that a scientific consensus exists on climate change. Certainly there is no consensus at the very top echelons of scientists -- the ranks from which I have been drawing my subjects -- and certainly there is no consensus among astrophysicists and other solar scientists, several of whom I have profiled. If anything, the majority view among these subsets of the scientific community may run in the opposite direction." ...
"Most of the deniers I have written about have suffered for their scientific findings -- some have been forced from their positions, others lost funding grants or been publicly criticized. In writing about these ... , I have inadvertently added to their anguish. None among [them] welcome the term "denier" -- a hateful word that I used ironically, but perhaps illadvisedly. ... The word "denier," of course, is employed to tar scientists who dissent from IPCC convention. In other disciplines, dissent is part of what's called 'the scientific method' and lauded."
In summary, one has to read Solomon's profiles one by one to fully appreciate his fact-based approach, each succinctly and very readably expressed. After finishing the chapters -- which can easily be read either serially or separately in one's own chosen sequence depending on particular preferences or interest -- one will be left wondering how much of the media hype one hears is believable and how much may be gauze either inadvertently or deliberately pulled over one's eyes. At the very least it should stimulate the reader to think about these matters to which many may not have given much attention beyond a bland acceptance of the usual commentary one hears in so much of the media.
