In the latest national survey conducted by the Yale Project on Climate Change Communication, nearly two-thirds of respondents reported that they believe climate change is happening and about half believed climate change is impacted by human activities. Interestingly, these numbers have remained relatively stable for the past years, perhaps, according to the report, because Americans aren't hearing about climate change very often. Findings like these are just the tip of the iceberg in terms of what is available on the site. Readers may browse Yale Climate Opinion Maps, which examine perceptions of climate change by state, congressional district, or county. They may also read peer-reviewed articles, as well as explanations of those articles, and watch a six-minute video that explains the results from the group's 2012 Six Americas Report.
