"Climate change poorly understood by US public, survey finds"
"The survey further found that the environment and climate change are not high-priority issues for the public. The environment came out 13th on a list of 22 possibilities for "the most important issues facing the U.S. today." And on a list of 10 specific environmental problems, "global warming" came up sixth, well behind water pollution and toxic waste"
By contrast, in Canada the leader of the Liberal party (in power from 1994 to 2005 'ish) has made the environment, particularly climate change, the foremost plank in his platform strategy to defeat the Conservatives, and may actually succeed.
From observation, it appears that in the US, the only people who're at all educated on the climate / environment as an issue are lobbyists working against making any improvements. Weird.
