چکیده:
The theory of climate change that most people are familiar with is commonly called anthropogenic (man-made) global warming, or AGW for short. That theory holds that man-made greenhouse gases, primarily carbon dioxide (CO2 ), are the predominant cause of the global warming that occurred during the past 50 years. In the past few years, confidence in the AGW theory has declined dramatically. New research points to natural causes of the modern warming, and stabilizing (by some measures, falling) global temperatures have called attention to long-recognized shortcomings of the AGW theory. Tens of thousands of scientists have signed petitions expressing their dissent from the so-called “consensus” in favor of AGW. Opinion polls show a majority of the public in the U.S. and in other countries no longer believes human activity is causing global warming. Evidence of the decline of the AGW theory is presented in the postscript to this booklet.
