These graphs illustrate national public opinion over time and across several sociodemographic variables, as well as political views, to show the diversity of Americans’ views on climate change and how much Americans engage with the issue.
About the Tool
Public opinion parameters are based on national survey data collected between 2008 and 2025 as part of the Climate Change in the American Mind (CCAM) project led by the Yale Program on Climate Change Communication and the George Mason Center for Climate Change Communication. Percentages refer to positive responses to questions (e.g., “Agree” or “Support”).
If results are not loading, make sure you have selected a question or reset the tool at the bottom right-hand of the tool. You can also refresh your web browser. Note that some questions were not asked every wave and may not have data for a given year.
NOTE: Sample sizes may be small for some groups (e.g., < 100 respondents) and results should be interpreted with caution. Hover over data points with your mouse to see the sample size of the group. Email climatechange@yale.edu for questions or comments about the CCAM Explorer or data.
