Global-warming deniers in U.S. declining, Yale study reports

Percentage of Americans who believe Earth is warming now up to 70%

Despite an intense politically and economically driven war against science, logic and common sense, more Americans are buying into the theory -- supported by the vast majority of climate researchers -- that the Earth actually, truly is warming. According to a a new study called "Climate Change in the American Mind," 70% of Americans surveyed last month said they believed in global warming, up from 57% in January 2010. Meanwhile, global warming deniers in the U.S. are dwindling, down to 12% last month from 20% in January 2010. The survey of about 1,000 U.S. adults was conducted by the Yale Project on Climate Change Communication and the George Mason University Center for Climate Change Communication. Other notable findings: * More than half of Americans (54%) believe human activity is the chief cause of global warming, up from 46% since last March. Those who insist natural changes are the main cause of global warming fell to 30% from 37% in March. * More Americans "are likely to believe most scientists agree that global warming is happening than believe there is disagreement on the subject," with 44% seeing consensus (up 9% since March) versus 36% who believe the scientific jury is still out. * More than three-quarters of those surveyed (76%) say they "trust climate scientists as a source of information about global warming." That's the good news. Here's the bad: Two-thirds of Americans (67%) trust scientists who aren't climate specialists for their global-warming information, while 60% trust TV weather reporters. Seriously, Americans? Do you go to a podiatrist to get an opinion about a skin rash? These numbers can fluctuate based on events and public discourse, but fortunately the trend is toward trusting climate scientists and believing there's a scientific consensus about global warming. Because, well, there is. Now read this:
