WASHINGTON, Jan. 30 /PRNewswire-USNewswire/ — Two powerful new books say today’s global warming is due not to human activity but primarily to a long, moderate solar-linked cycle. “Unstoppable Global Warming Every 1500 Years,” by physicist Fred Singer and economist Dennis Avery was released just before Christmas. “The Chilling Stars: A New Theory of Climate Change,” by Danish physicist Henrik Svensmark and former BBC science writer Nigel Calder (Icon Books), is due out in March.
Singer and Avery note that most of the earth’s recent warming occurred before 1940, and thus before much human-emitted CO2. Moreover, physical evidence shows 600 moderate warmings in the earth’s last million years. The evidence ranges from ancient Nile flood records, Chinese court documents and Roman wine grapes to modern spectral analysis of polar ice cores, deep seabed sediments and layered cave stalagmites.
“Unstoppable Global Warming” shows the earth’s temperatures following variations in solar intensity through centuries of sunspot records, and finds cycles of sun-linked isotopes in ice and tree rings. The book cites the work of Svensmark, who says cosmic rays vary the earth’s temperatures by creating more or fewer of the low, wet clouds that cool the earth. It notes that global climate models can’t accurately register cloud effects.
