Stephen H. Schneider, Ph.D., is a recipient of a MacArthur “Genius Grant” and the collective 2007 Nobel Peace Prize with his colleagues on the Intergovernmental Panel on Climate Change (IPCC). He has been an expert adviser to every presidential administration since Nixon. He is the Melvin and Joan Lane professor for interdisciplinary environmental studies, a professor in the Department of Biology, and a senior fellow at the Woods Institute for the Environment at Stanford. He was a National Center for Atmospheric Research scientist from 1973-1996, where he co-founded the Climate Project.

Schneider focuses on climate change science, integrated assessment of ecological and economic impacts of human-induced climate change, and identifying viable climate policies and technological solutions. He has consulted for federal agencies and White House staff in six administrations.

Involved with the Intergovernmental Panel on Climate Change since 1988, he was a coordinating lead author, Working Group II, on chapter 19 of "Assessing Key Vulnerabilities and the Risk from Climate Change,” as well as a synthesis author for the Fourth Assessment Report.

Schneider, along with four generations of IPCC authors, received a collective Nobel Peace Prize for their joint efforts in 2007. Elected to the US National Academy of Sciences in 2002, Schneider received the American Association for the Advancement of Science/ Westinghouse Award for Public Understanding of Science and Technology and a MacArthur Fellowship for integrating and interpreting the results of global climate research.

Founder/editor of Climatic Change, he has authored or co-authored over 500 books, scientific papers, proceedings, and legislative testimonies, and has edited books and chapters, reviews, and editorials. Schneider counsels policy makers, corporate executives, and non-profit stakeholders about using risk management strategies in climate-policy decision-making, given the uncertainties in future projections of global climate change and climate impacts. He is actively engaged in improving public understanding of science and the environment through extensive media appearances and communications and public outreach. He lives in California.

Editor's Note: Climatologist Stephen Schneider died suddenly on July 19, 2010, aboard a flight as it was landing in London. The New York Times called Stephen a "climate warrior" for his longstanding campaign to inspire an aggressive response to warming. Stephen was at National Geographic headquarters in June to participate in the Society's annual Explorers Symposium. He was 65 years old.
