This report describes the results of four waves of national surveys conducted from 2 July 2019 to 2 May 2020. The sample includes 14,888 adults (age 18+) in the U.S. All national surveys were conducted at three-month intervals. This research was supported by the National Science Foundation.

We find that most Americans have heard about the concept of climate change adaptation and most support adaptation efforts by local government. Although concern about extreme weather in local communities is split, nearly half of respondents think their community members will be harmed by extreme weather in the next five years. A majority of respondents are confident that they can prepare themselves for extreme weather, but a majority also doubt that their local government can prepare their community. Over four waves the percentage of respondents reporting personal experience with climate-related extreme weather events has declined, alongside slight decreases in perceived risks from extreme weather.
