The study you see above was done by the Yale University Project on Climate Change. The red band shows the percentage of people who "believe the action is important, but do not currently engage in it." The blue band represents those who "believe the action is important and currently engage in it." The Greys believe the action is unimportant and don't do it. It seems pretty clear where many of us fall, unfortunately.
The study—Americans' Actions to Conserve Energy, Reduce Waste, and Limit Global Warming— also seems to indicate that "not only are we hypocrites but we are going backward; when asked, 'In the coming year, do you intend to do this less often, the same or more often?' In most cases where there is a comparison to 2008, the answer is that fewer people care.'"
What do you think about this?
