“Although Fox discussed climate change most often, the tone of its coverage was disproportionately dismissive,” says the study by four professors, two from George Mason University, the others from Yale and American University. They wrote, “Fox broadcasts were more likely to include statements that challenged the scientific agreement on climate change, undermined the reality of climate change, and questioned its human causes.”…

The study acknowledges that Fox was the most balanced from the numbers perspective, but the network still gets an F. The reason, it says, is because viewers are influenced by what they see, and seeing more critics of global warming makes more viewers critics. “The more often people watched Fox News, the less accepting they were of global warming. Conversely, frequent CNN and MSNBC viewing was associated with greater acceptance of global warming,” the study concludes.
