Concern about climate change is widespread, especially among young people. How might these concerns be affecting plans for the future, such as decisions about childbearing and financial planning? This paper examines impacts of climate change concerns on future planning among U.S. residents. First, we examined the ways in which people were engaging with these questions with an AI analysis of social media posts (using AskPolly). In social media posts, people who engaged with the topic mostly expected profound impacts, and they reported that it was leading them to seek information and to be more politically engaged. We then present the results of an online study of 324 U.S. respondents. In survey responses, concern about climate change was high, especially among younger, better educated, more leftwing, and Black respondents; people high in climate anxiety, and more future-oriented, also showed greater concern. People expected more negative than positive impacts, more negative impacts in the future than in the present, and more negative impacts to others than to themselves. They reported that their concerns were having some impact on their future planning, especially about where to live. Although people on the left were more likely to think about, and worry about, climate change, political orientation had little influence on reported impacts; younger age, higher level of education, and degree of climate anxiety were the strongest predictors of both felt and anticipated impacts as well as the degree to which concerns were affecting future plans. Results suggest that climate change concerns are significantly affecting people's lived experience and decisions about the future.
