We examine how responses to individuals displaced by environmental shocks vary based on the ethnicity of the migrants, the locals, and their ethnic groups’ political status. We embed an experiment into a stratified sample of 2,188 white, Black, and Latinx Americans surveyed through Qualtrics Panels. The experiment shows respondents a photo of a flooded road, randomly assigning whether there are white, Black, Latinx, or no persons wading through the water. Results show no outward change in approval for migrants settling in respondents’ neighborhoods based on their ethnicity. However, emotional responses to migrants, perceptions of migrants’ economic backgrounds, and levels of tolerance and ethnocentrism among locals vary based on migrants’ ethnicity. While there may not be outward xenophobia and conflict in the face of internal climate-related migration, the underlying attitudes of members of receiving communities suggest internal migrants from politically excluded groups lack local acceptance and may face more subtle prejudice.
