Global Warming: the basics

Walter Williams points us to a source on global warming hysteria:

There's an excellent booklet available from the National Center for Policy Analysis ( titled "A Global Warming Primer." Some of its highlights are:

"Over long periods of time, there is no close relationship between CO2 levels and temperature."

"Humans contribute approximately 3.4 percent of annual CO2 levels" compared to 96.6 percent by nature.

"There was an explosion of life forms 550 million years ago (Cambrian Period) when CO2 levels were 18 times higher than today. During the Jurassic Period, when dinosaurs roamed the Earth, CO2 levels were as much as nine times higher than today."
Have a look for yourself. It's a 40-page pdf, mostly filled with charts and graphs to make it easier to understand. Footnoted, too.
