The Yale Project on Climate Change Communication has an updated version of its report, Global Warming’s Six Americasout this month. The report, which identifies and explores six major attitudes towards climate change, shows that the number of Americans alarmed about climate change has risen from 10 to 16 percent of the population over the last two years.  

At the same time, those dismissive towards the reality of climate change have decreased in size, from 16 percent in 2010 to 8 percent in 2012.  

The “Six Americas” of the title refers to six predominant postures toward climate change in the United States, grouped by researchers along a spectrum of concern and engagement, from “Alarmed” to “Dismissive.” By focusing on attitude rather than demographics, these groupings represent cohesive yet widely diverse cross-sections of the public.
