Unstoppable Global Warming: Every 1,500 Years, Updated and Expanded Edition

In this New York Times bestseller, authors Singer and Avery present the compelling concept that global temperatures have been rising mostly or entirely because of a natural cycle. Using historic data from two millennia of recorded history combined with natural physical records, the authors argue that the 1,500 year solar-driven cycle that has always controlled the earth's climate remains the driving force in the current warming trend.
