The Program


We conduct scientific studies on public opinion and behavior; inform the decision-making of governments, media, companies, and advocates; educate the public about climate change; and help build public and political will for climate action.

Global warming is one of the greatest threats – and opportunities – of the 21st century. Our fate will be determined by the choices of 8 billion people and counting. We are social scientists studying the causes and consequences of public opinion and behavior. We help governments, media, companies, and advocates communicate more effectively. And we publish an online climate news service and daily national radio program, Yale Climate Connections.

The Yale Program is directed by Dr. Anthony Leiserowitz. For more information about the YPCCC team, please see People & Partners. The Program is part of the Yale School of the Environment at Yale University, in New Haven, Connecticut.

What We Do

We conduct public opinion and messaging research, using surveys, experiments, qualitative methods, statistical models, maps and participatory GIS, among other methods. We also conduct studies at the global, national, and local scales. Major projects include Climate Change in the American Mind, The Yale Climate Opinion Maps, and International Attitudes & Behavior. We also publish Yale Climate Connections - an online climate news service and national radio broadcast. Finally, we help governments, media, companies, and advocates communicate more effectively.

To learn more about our current projects see Our Projects.

Mission & History

The Program grew out of a groundbreaking conference on “Americans and Climate Change” convened in 2005 in Aspen, CO by the Yale School of Forestry & Environmental Studies, now the Yale School of the Environment. Over 100 national leaders representing science, media, religion, politics, entertainment, education, business, environmentalism, and civil society developed an action plan to engage American society. The recommendations from the conference are available online in the report "Americans and Climate Change: Closing the gap between science and action."
