Solar and Celestial Causes of Global Warming
Donald W. Miller, Jr., MD
An estimated one billion people watched former Vice President Al Gore receive an Oscar for An Inconvenient Truth. In this film about global warming, Gore uses slides from lectures he gives on this subject, personal anecdotes, and footage of collapsing Antarctic ice shelves, receding glaciers, and marooned polar bears to warn us that human-made greenhouse gases are heating the planet to dangerous levels. The principal greenhouse gas that humans make, burning coal, oil, and natural gas for energy, is carbon dioxide (CO2). (In 1750, at the beginning of the Industrial Era, the earth’s atmospheric CO2 concentration was 280 parts per million by volume. In 1960 it had risen to 315 ppmv, and it is now 383 ppmv.)
There is another theory of global warming and cooling that Gore does not address in An Inconvenient Truth. The Solar/Cosmic Ray Theory posits that cosmic rays, not humans, cause climate change. The Chilling Stars: A New Theory of Climate Change (2007) by Henrik Svensmark and Nigel Calder is the first book to be published on this subject. Svensmark proposed this theory in 1996 and supplies the scientific input for the book. Calder, a British science writer, "strung the words together," as he puts it. He does this very well and explains Svensmark’s theory in an engaging and easily understandable way. It will be published in the U.S. March 25 (I obtained my copy from the UK, where it was published last month).
