The Yale and George Mason Centers on Climate Change Communication, collaborators on the well-known “Six Americas” studies of how the public views global warming, are out with their latest report, the fifth in the series. And it hints at an underlying theme discernible in many of these surveys: On climate change, the U.S. public is a lot like a weather vane. When there’s freaky weather—like now–people increasingly worry about global warming. When the weather is what they’re used to and expect, not so much.
Let’s start with some background on the “Six Americas” study: It began in the fall of 2008, that hopeful time when Barack Obama was soon to win the U.S. presidency and many thought he’d address the global warming problem within the short space of a year. In those days, fully half of the public fell into the two “Six Americas” audience segments that evince the most worry about global warming—the “Alarmed” and the “Concerned.” Yet by January of 2010–following “ClimateGate” and the failed Copenhagen summit–the number of Americans falling into these two segments had tumbled by 11 percentage points. Meanwhile, the denialist segment of the public—the “Dismissive” category—had ballooned dramatically, from 7 percent to 16 percent.
Those were sad and depressing days for science and environment advocates; and when it comes to public opinion, we have not yet clawed back to where we were in the fall of 2008. But what the latest survey hints at is that the public is growing more concerned again—a finding that is particularly noteworthy in that these data only run through March of 2012, and thus really only take into account the freakily warm winter (not, you know, the summer heat waves, wildfires, and drought).
I’m betting that since March 2012, Americans have gotten even more alarmed over global warming–perhaps moving all the way back to where they were in fall 2008.
