Author Disputes Evidence of Global Warming

Global warming may have been the impetus for the environmental agreement signed in Kyoto, Japan, in December, but is it a scientifically proven phenomenon? Astrophysicist S. Fred Singer, author of Hot Talk, Cold Science, contends that contrary to the beliefs of some scientists and politicians, evidence of global warming is neither settled, compelling nor convincing. "On the contrary, scientists continue to discover new mechanisms for climate change and to put forth new theories to try to account for the fact that global temperature is not rising, even though greenhouse theory says it should," Singer says. Published by The Independent Institute, Oakland, Calif., the book includes suggestions that higher carbon dioxide levels in the atmosphere may even be beneficial.
