A hotter planet could lead to more violence, according to Craig Anderson, PhD, a professor of psychology at Iowa State University. 


Studies show warmer temperatures have been associated with increased irritability and aggressive behavior, he told attendees over the weekend at the Annual Convention of the American Psychological Association. 

Dr. Anderson presented data from the last 50 years, which showed murders and assaults go up in the summer months. He also discussed how global warming could create a dramatic shift in the availability of resources in certain areas. 

“If temperatures keep rising,” he said, “we can expect to see increased violence on the list of negative social consequences of global warming.” 

In another presentation, psychologist Frances Kuo, PhD, an associate professor at the University of Illinois at Urbana-Champaign, presented evidence from several international studies that showed nature deprivation may lead to social, psychological and physical breakdown in humans.
