Marcia McNuttMarcia McNutt is a geophysicist and president of the National Academy of Sciences. From 2013 to 2016, she served as editor-in-chief of the Science family of journals. Prior to joining Science, she was director of the U.S. Geological Survey (USGS) from 2009 to 2013. During her tenure, the USGS responded to a number of major disasters, including earthquakes in Haiti, Chile, and Japan, and the Deepwater Horizon oil spill. McNutt led a team of government scientists and engineers at BP headquarters in Houston who helped contain the oil and cap the well. She directed the flow rate technical group that estimated the rate of oil discharge during the spill’s active phase. For her contributions, she was awarded the U.S. Coast Guard’s Meritorious Service Medal.

Before joining the USGS, McNutt served as president and chief executive officer of the Monterey Bay Aquarium Research Institute (MBARI), in Moss Landing, California. During her time at MBARI, the institution became a leader in developing biological and chemical sensors for remote ocean deployment, installed the first deep-sea cabled observatory in U.S. waters, and advanced the integration of artificial intelligence into autonomous underwater vehicles for complex undersea missions. McNutt received a B.A. in physics from Colorado College and her Ph.D. in earth sciences at the Scripps Institution of Oceanography.


Chris FieldChristopher B. Field is the Perry L. McCarty Director of the Stanford Woods Institute for the Environment and the Melvin and Joan Lane Professor for Interdisciplinary Environmental Studies in the Biology Department of the School of Humanities and Sciences at Stanford University. He is also a Professor of Earth System Science in the Stanford School of Earth, Energy & Environmental Sciences and a Senior Fellow at the Stanford Precourt Institute for Energy. Prior to his appointment as Woods' director, Field served as Director of the Carnegie Institution for Science's Department of Global Ecology, which he founded in 2002. Field's tenure at the Carnegie Institution dates back to 1984.

Field's research focuses on climate change, ranging from work on improving climate models to prospects for renewable energy systems and community organizations that can minimize the risk of a tragedy of the commons. He has been deeply involved with national- and international-scale efforts to advance science and assessment related to global ecology and climate change. He served as co-chair of Working Group II of the Intergovernmental Panel on Climate Change (IPCC) from 2008 to 2015, where he led the effort behind a special report, “Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation” (2012), and the working group’s contribution to the IPCC Fifth Assessment Report, “Climate Change 2014: Impacts, Adaptation, and Vulnerability(2014). Field assumed leadership of Woods in September 2016. He holds a bachelor’s degree in biology from Harvard College and a Ph.D. in biology from Stanford.

Noah DiffenbaughNoah Diffenbaugh is a Professor in the School of Earth, Energy and Environmental Sciences and Senior Fellow at the Stanford Woods Institute for the Environment. His research interests are centered on the dynamics and impacts of climate variability and change, including the role of humans as a coupled component of the climate system. Much of his work has focused on the role of fine-scale processes in shaping climate change impacts, including studies of extreme weather, water resources, agriculture, human health and poverty vulnerability. Diffenbaugh is currently a lead author for Working Group II of the Intergovernmental Panel on Climate Change (IPCC) and a member of the National Academy of Sciences Ad Hoc Committee on Effects of Provisions in the Internal Revenue Code on Greenhouse Gas Emissions. He also serves on the Executive Committee of the Atmospheric Sciences Section of the American Geophysical Union (AGU), as an editor of Geophysical Research Letters, and as a member representative to the University Corporation for Atmospheric Research (UCAR).

Diffenbaugh is a recipient of the James R. Holton Award from the American Geophysical Union, a CAREER award from the National Science Foundation, and a Terman Fellowship from Stanford University. He has been recognized as a Kavli Fellow by the U.S. National Academy of Sciences and as a Google Science Communication Fellow. Before coming to Stanford, Diffenbaugh was a member of the faculty of Purdue University, where he was a University Faculty Scholar and served as Interim Director of the Purdue Climate Change Research Center (PCCRC).

Katharine MachKatharine Mach is a Senior Research Scientist at Stanford University and a Visiting Investigator at the Carnegie Institution for Science. She leads the Stanford Environment Assessment Facility (SEAF). Her research is focused on integrative assessment of climate change risks and response options, with the goal of innovating and evaluating new approaches to assessment that can inform decisions and policy. From 2010 to 2015, Mach codirected the scientific activities of Working Group II of the Intergovernmental Panel on Climate Change (IPCC), which focused on impacts, adaptation and vulnerability. This work culminated in the IPCC’s Fifth Assessment Report and its Special Report, “Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation.” Mach received her bachelor’s degree from Harvard College and her Ph.D. from Stanford.


Carter RobertsCarter Roberts is President and CEO of World Wildlife Fund in the United States. WWF, the world’s largest network of international conservation organizations, works across 100 countries and enjoys the support of 5 million members worldwide. Roberts leads WWF’s efforts to save the world’s great ecosystems and address climate change by linking science, field and policy programs with an ambitious initiative to work with markets and businesses to lighten their impact on the planet. He has worked with communities and heads of state in North America, Africa, Latin America and Asia; and has built partnerships with some of the world’s largest corporations, including Walmart, Cargill and Mars to set new industry standards for resource efficiency. Roberts earned his MBA from Harvard Business School following a BA from Princeton University, and subsequently held marketing management positions for Procter & Gamble and Gillette. He went on to lead international conservation and science programs for fifteen years at The Nature Conservancy before coming to WWF in 2004.
