Global-warming denialism, June 11, 2005: “Professor Fred Singer, president of the Science and Environmental Policy Project based in Arlington, Virginia … told the BBC News there was no firm evidence of global warming. He claimed the data was contradictory and there was no consensus within the scientific community. He said: ‘There is simply no consensus. That’s a myth. Even if there were a warming, it’s a question of how much. Obviously, the greenhouse effect is real; the problem is the data do not show a significant warming since 1940.'” (BBC News found at the SEPP Web site.)

Global-warming denialism, October 2006: “The Earth’s recent warming trend isn’t a product of human activity, but rather caused by a solar-linked cycle that creates harmless, naturally warmer temperatures approximately every 1,500 years, write Dennis Avery and Fred Singer in their controversial new book Unstoppable Global Warming: Every 1,500 Years.” (Press release at Avery’s Hudson Institute.)

I look forward to reading the book and finding what striking new research finding led to this dramatic turnaround.
