Unstoppable Global Warming
Unstoppable Global Warming: Every 1500 Years is a 2007 book, by Fred Singer and Dennis Avery, which presents "in popular language supported by in-depth scientific evidence the compelling concept that global temperatures have been rising mostly or entirely because of a natural cycle. Unstoppable Global Warming explains why we're warming, why it's not very dangerous, and why we can't stop it anyway." 
The book presents the evidence for cyclical periods of global warming and global cooling throughout the earth's history. It also debunks many media-promoted myths and scare tactics being promoted during the current scare over global warming, such as predictions of violent weather, species extinctions, and famines.
