Individuals can act to mitigate climate change and its consequences by changing their own behavior, working with others to address community issues, or advocating for government action. However, little is known about what people are doing or the factors shaping their engagement. We surveyed 741 respondents in the United States to understand their current beliefs, motivations, and behaviors related to climate action. Our respondents report frequently taking everyday actions, such as talking to others about climate change and buying climate friendly products with less frequent, but still higher than expected, advocacy-oriented actions like signing petitions or contacting representatives. We find wide agreement on the importance of government action and the need for government to hear people’s concerns, with more variability in the importance assigned to community and individual actions. Lack of access to resources, social support, or fun approaches to addressing climate change represent obstacles to further action.
