It's encouraging, even in this age of intense politicizing of what should be a scientific issue (namely, climate change) that most Americans at least recognize that the earth is warming and support increased research into renewable technologies. What is concerning, however, is that failure of most people to realize that there is an overwhelming scientific consensus that humans are the cause of climate change. It would appear the "climate skeptic" lobby and media have done a pretty good job in promoting misinformation and general confusion.
