John Holdren crams a staggering amount of misinformation into one quote

Global Warming: As Machiavelli May Have Seen It

Last, consider this strong statement that Friedman quotes from John Holdren, professor of environmental policy at Harvard, director of the Woods Hole Research Center, and former president of the American Association for the Advancement of Science: “The most important conclusions about global climatic disruption–that it’s real, that it’s accelerating, that it’s already doing significant harm, that human activities are responsible for most of it, that tipping points into really catastrophic disruption likely lurk along the ‘business as usual’ trajectory, and that there is much that could be done to reduce the danger at affordable cost if only we would get started–have not been concocted by the Sierra Club or the enemies of capitalism. They are based on an immense edifice of painstaking studies published in the world’s leading peer-reviewed scientific journals. They have been vetted and documented in excruciating detail by the largest, longest, costliest, most international, most interdisciplinary, and most thorough formal review of a scientific topic ever conducted.”
