John P. Holdren provides the context for and an overview of the recommendations made by the National Commission on Energy Policy its 2004 and 2007 reports to the President and Congress of the United States.

Holdren presents a detailed summary of the science behind global climate disruption, and offers a look at the technologies that can help mitigate future risk. He then surveys current thinking on the economics of climate disruption and proposes practical steps forward.

Someone usually asks Holdren why we should be worried about it. Holdren, who has been thinking about climate change since the late 1960s, has a prepared list: “Heat waves, drought, wildfires, rising sea level, reduced agricultural productivity, damage to ocean fisheries, loss of coral reefs,” he says. “I mean, I have a much longer litany,” he reminds his audience. This isn’t just about beach erosion on Cape Cod or warmer summers in Europe, it’s about trying to preserve the conditions for our economic, social, and political well-being.

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."

John P. Holdren presented the John H. Chafee Memorial Lecture on Science and the Environment on January 17, 2008, at the Ronald Reagan Building and International Trade Center in Washington, D.C. Holdren's lecture was presented during the 8th National Conference on Science, Policy and the Environment: Climate Change: Science and Solutions, organized by the National Council for Science and the Environment.

The Chafee Memorial Lecture is presented in memory of the late Senator John Chafee of Rhode Island, who was a champion of bipartisan, scientific approaches for protecting the environment.

Science, Technology, and Public Policy Program Director John P. Holdren spoke at a Woods Hole Research Center–sponsored side event at the 13th United Nations Framework Convention on Climate Change in Bali, Indonesia.

"Global warming is a misnomer," said John P. Holdren, speaking at the John F. Kennedy Jr. Forum at the Kennedy School on November 6. "It implies something gradual, uniform, and benign. What we’re experiencing is none of these."

Holdren also urged the United States to spearhead this effort, going from being a "laggard in climate policy to being a leader." Once that happens, he said, the rest of the world will follow suit.

John P. Holdren, director of the Belfer Center's Science, Technology, and Public Policy program, notes that with the selection of the Intergovernmental Panel on Climate Change (IPCC) and Al Gore for the 2007 Nobel Peace Prize, "the Nobel committee is emphasizing that peace, prosperity, and the fate of the environment are intertwined."

Science, Technology, and Public Policy Program Director John P. Holdren was interviewed for "Ahead of the Curve: Business Responds to Climate Change", a Sea Studios Foundation video about how U.S. corporations are responding to the challenge of reducing greenhouse gas emissions while maintaining competitiveness and profitability.

John P. Holdren, director of the Belfer Center's Science, Technology, and Public Policy Program, moderated the Energy & Climate panel "Stabilizing the Climate: Pathways to Success" at the Clinton Global Initiative Annual Meeting in New York on September 27, 2007.
