Research Data Is Not False



An individual named Terry Putnam did a grave disservice to your readers by making false and defamatory statements about me and my climate scientist colleagues.

Mr. Putnam attacks the integrity of researchers at the UK’s University of East Anglia “Climatic Research Unit” (CRU), misrepresenting the content of stolen e-mails to falsely accuse them of “falsifying data.” He fails to note that seven separate external investigations in the U.S. and the U.K. have absolved the scientists of claims of wrongdoing manufactured by climate change deniers.

Mr. Putnam makes the libelous claim that the so-called “hockey stick”— work of my own published more than a decade ago showing that recent warming is unusual over at least the past 1,000 years—has been “proven to be a fraud.” He ignores the fact that the highest scientific body in the nation, the National Academy of Sciences, affirmed my research findings in an exhaustive independent review published in June 2006 (see e.g. “Science Panel Backs Study on Warming Climate,” New York Times, June 22, 2006, among many others). Dozens of independent groups of scientists have independently come to the same conclusion, and more recent work by several groups shows that the recent warmth is unusual over an even longer timeframe.

Readers interested in the truth behind the science, rather than the falsehoods and smears perpetuated by people like Mr. Putnam, should consult the scientist-run Web site: http://www.realclimate .org, or scientifically-based books on the topic like my “Dire Predictions: Understanding Global Warming.”

How does anyone know what the temperture was 1000 yrs ago?

Mr. Terry Putnam told the truth.

Michael E. Mann lied... the documents prove it. His lies are lies of omission. He leaves out facts when it suits his purpose.

Another often repeated lie is that our sea levels are rising. That is NOT true. And guess who just bought a mansion on the beach in California? Al Gore! The same Al Gore that preaches that a rising sea level will soon flood the world's coastal areas!

It would be hard to find bigger liars than these global warming, pseudo-scientists like Gore and Mann. "Global warming" is nothing more than a scam to make these people richer and you POORER.

Pat, Here's how they figured it out......Prof. Mann called Al Gore. Al went to were they are keeping that 1000 yr. old woolly mammoth they found a few years ago in Siberia. Al took its temperature, Al called Prof. Mann back and told him...a 1000 years ago it was COLD. :)
