Applying science to the politically charged global warming debate, this text incorporates the work of scholars from around the world who address the issue without institutional bias. It presents evidence concluding that climate change is moderate and predominantly a natural process, that predictions of destructive warming are unreliable, and that the economic and humanitarian costs of trying to reverse climate change are certain to cause unprecedented human suffering. The book includes real climatology data and CO2 levels over tens of thousands of years. It also includes high-end graphics and relevant links to federal, state, and professional sites.
