We are pleased to announce a new interactive mapping tool called “Yale Climate Opinion Maps” (YCOM) and an accompanying peer-reviewed paper in the journal Nature Climate Change. This tool allows users to visualize and explore differences in public opinion about global warming in the United States in unprecedented geographic detail, as the map of public worry about global warming below illustrates. As you can see, 52% of Americans are worried about global warming. But this national number glosses over the enormous geographic diversity in public opinion across the country – diversity that is revealed for the first time in these maps.
