Greenhouse Extinctions

Earthfiles investigative reporter Linda Moulton Howe discussed the bizarre story of the alleged human-alien hybrid found dead in Los Angeles and said to be involved with the CIA; mysterious and spectacular crop formations found in the wheat fields of Wiltshire, England on the summer solstice this past June, and the breaking story about the sun going to sleep in 2030 and ushering in a brutal mini ice age across the planet.

In the first hour, political commentator and economist John Lott reacted to the shooting of two reporters in Virginia on Wednesday and the ramifications the event may have on gun laws.

Greenhouse Extinctions

Show Archive
Date: Saturday - May 26, 2007
Host: Art Bell
Guests: Peter Ward

Professor of Earth and Space Sciences and Astrobiologist for NASA, Peter Ward (Book Link) discussed his vision of the end of the world based on past mass extinctions.

While most scientists agree that a meteor impact killed the dinosaurs 65 million years ago, Ward said our planet's 15 other ancient mass extinctions were caused by short-term global warming. According to Ward, high levels of CO2 increased global temperatures, contributing to conditions that gave rise to a series of bacteria in the oceans that produced toxic hydrogen sulfide gas. Eventually, this gas erupted into the atmosphere and poisoned animals and plants on the planet's surface.

Atmospheric CO2 is currently at 380 ppm and rising 2 ppm every year, Ward explained. He said the geological record indicates 'greenhouse extinctions' occur when CO2 levels go beyond 1000 ppm and when all the ice caps have melted. Ward estimated that we have 1000 years before this mass extinction process begins, unless we begin reducing man-made CO2 emissions now. In the meantime, we can expect a host of problems, including coastal flooding and food shortages, caused by rising sea levels, he warned.
