Some of our recent research with the Cornell Atkinson Center for Sustainability explores support of climate change and policies to mitigate it has taught us that in some cultures in the U.S., a set of voices in our heads has a powerful influence in what we believe. Specifically, stronger familism among U.S. Latinos predicted increased support for climate policies, including greater understanding of the scientific consensus on climate change (a "gateway" belief in supporting climate action). For non-Hispanic whites, the best predictor of climate policy support, perception of scientific consensus and certainty about climate change was their political ideology.
