Obama Science Advisor John Holdren Schools Political Scientist Roger Pielke On Climate And Drought

By Joe Romm

In an unprecedented move, the President’s Science Advisor, Dr. John P. Holdren, has published a devastating 6-page debunking of one of the country’s leading climate confusionists, Roger Pielke Jr.

I’ll excerpt Holdren’s comprehensive critique, “Drought and Global Climate Change,” below. Worsening drought may be the climate impact that affects the most people in the coming decades, as I discussed in my 2011 literature review in the journal Nature. It is valuable to see the the subject laid out so clearly by the nation’s top scientist...understanding of drought and climate change is evolving pretty rapidly, so even the latest IPCC reports are already out of date. Having read much of the recent drought literature and interviewed many of the leading drought experts in the last few years, I can say that Holdren’s views are right in the mainstream of climatologists’ view of drought. I can think of no climate scientists who share Pielke’s startling assessment of Holdren’s views as “zombie science.”...some drought experts believe the situation is considerably worse than is widely understood. As one top researcher on the climate-drought link confirmed with me recently, “The U.S. may never again return to the relatively wet conditions experienced from 1977 to 1999.”

HOLDREN AND PIELKE
John Holdren is one of the most distinguished scientists in America. He is a past president of the American Association for the Advancement of Science. Author of over 200 articles and papers, Holdren is a member of the National Academy of Sciences, the National Academy of Engineering, and a foreign member of the U.K.’s Royal Society.

I have known Holdren for more than two decades, and not only does he have more breadth of knowledge on all things climate than most, he is very judicious in his choice of words.

Roger Pielke Jr. is a political scientist who has publicly questioned the scientific integrity of more climate scientists than just about anyone else on the planet. He has smeared literally hundreds of scientists (as I document here).
