A picture might be worth a thousand words -- and still not convince people that climate change is happening. Recent research suggests that images of devastating floods, cracked fields of earth and roaring hurricanes might be less effective at conveying the emotional impacts of extreme weather than media outlets think. They can be too scary, or of places too far away. Others might cause a yawn. Either way, it's likely that many pictures of disasters are tossed in the psychological trash can, even as extreme weather events seem to be increasingly damaging to communities and economies.
