In August of 2009, I wrote about the findings from the report of the American Psychological Association's (APA) task force studying the interface between psychology and global climate change. That report was in a way, a call to action for additional research and work to better understand the role of human behavior in climate change, the reasons people are not acting and ways to get people to act. The report made clear the many ways psychology as a discipline has important contributions to make in understanding climate change and helping to reverse it.
Jumping forward two years and the May/June 2011 issue of American Psychologist (APA's official journal) is a devoted special issue and follow up to that earlier report.
