Climate, sea level, and ice sheets have always changed, and the changes observed today are less than those of the past. Climate changes are cyclical and are driven by the Earth's position in the galaxy, the sun, wobbles in the Earth's orbit, ocean currents, and plate tectonics. In previous times, atmospheric carbon dioxide was far higher than at present but did not drive climate change. No runaway greenhouse effect or acid oceans occurred during times of excessively high carbon dioxide. During past glaciations, carbon dioxide was higher than it is today. The non-scientific popular political view is that humans change climate. Do we have reason for concern about possible human-induced climate change? This book's 504 pages and over 2,300 references to peer-reviewed scientific literature and other authoritative sources engagingly synthesize what we know about the sun, earth, ice, water, and air. Importantly, in a parallel to his 1994 book challenging "creation science," Telling Lies for God, Ian Plimer describes Al Gore's book and movie An Inconvenient Truth as long on scientific "misrepresentations." "Trying to deal with these misrepresentations is somewhat like trying to argue with creationists," he writes, "who misquote, concoct evidence, quote out of context, ignore contrary evidence, and create evidence ex nihilo."

Are pupils, parents and the public being fed political propaganda on climate change? Now is your chance to find out. Professor Plimer gives 101 simple questions with answers for you to ask teachers, activists, journalists and politicians. The climate industry adjusts the temperature record and withholds raw data, computer codes and information from scrutiny. Computer predictions of a scary future don't agree with measurements. Past natural climate changes have been larger and more rapid than the worst case predictions yet humans adapted. Is human-induced global warming the biggest financial and scientific scam in history? If it is, we will pay dearly. About the author: PROFESSOR IAN PLIMER (The University of Adelaide) is Australia's best-known geologist. He is also Emeritus Professor of Earth Sciences at The University of Melbourne where he was Professor and Head of Earth Sciences (1991-2005) after serving at The University of Newcastle (1985-1991) as Professor and Head of Geology. He was on the staff of the University of New England, The University of New South Wales and Macquarie University. He has published more than 120 scientific papers on geology. This is his eighth book written for the general public, the best known of which are Telling lies for God (Random House), Milos-Geologic History (Koan), A Short History of Planet Earth (ABC Books) and his best-selling Heaven+Earth (Connor Court). He won the Leopold von Buch Plakette (German Geological Society), Clarke Medal (Royal Society of NSW), Sir Willis Connolly Medal (Australasian Institute of Mining and Metallurgy), was elected Fellow of the Australian Academy of Technological Sciences and Engineering and was elected Honorary Fellow of the Geological Society of London. In 1995, he was Australian Humanist of the Year and later was awarded the Centenary Medal. He was Managing Editor of Mineralium Deposita, president of the SGA, president of IAGOD, president of the Australian Geoscience Council and sat on the Earth Sciences Committee of the Australian Research Council for many years. He won the Eureka Prize for the promotion of science, the Eureka Prize for A Short History of Planet Earth and the Michael Daley Prize (now a Eureka Prize) for science broadcasting. He is an advisor to governments and corporations and a regular broadcaster.
