About Mason 4C

The Center for Climate Change Communication at George Mason University conducts research on public opinion, messaging, and behavior related to climate change. We generate survey data, audience segmentation, message-testing results, and tools to support researchers, communicators, journalists, policymakers, and educators.

Collaboration History — Yale & George Mason

The Center for Climate Change Communication at George Mason University and the Yale Program on Climate Change Communication have maintained a long-standing research partnership focused on public opinion, audience segmentation, and communication strategies for climate change. This collaboration began with the development and launch of the Climate Change in the American Mind multi-wave survey (first fielded in 2009) and the Global Warming’s Six Americas segmentation. Since then, the teams have co-designed surveys and experiments, co-authored reports and peer‑reviewed papers, shared modeled datasets and analytic methods (including the Yale Climate Opinion Maps), and coordinated public-facing tools such as SASSY. The partnership combines complementary expertise in survey research, message-testing, and applied communication to produce reproducible data, practical guidance, and resources for researchers and policymakers.

Key Projects and Resources

  • Climate Change in the American Mind: A flagship, multi-wave survey program (in partnership with Yale) tracking U.S. public opinion on climate change since 2009. Reports and wave-level summaries are available on our reports page.
  • Global Warming’s Six Americas: A validated audience segmentation describing six distinct U.S. opinion segments used for research and targeted communication strategies. Documentation and related studies are listed on our site.
  • Yale Climate Opinion Maps (YCOM): Modeled subnational opinion estimates (state, county, Congressional district, metro) covering ~38 climate questions. The interactive YCOM tool is hosted by Yale; the underlying dataset is available in machine-readable (JSON) format at the linked data resource.
  • Message Experiments: Randomized studies testing which messages and messengers influence attitudes, knowledge, and behavior across different audience segments.
  • SASSY (Six Americas Super Short Survey): A four-question classifier that maps respondents to a Six Americas segment; accessible via our link.

Data Access and AI Use
