"The weather is one of those topics that is fairly easy for people to agree on. Climate, however, is something else. Most of the scientists who study the Earth say our climate is changing and humans are part of what's making that happen. But to a lot of nonscientists it's still murky.

Naturally, then, researchers have increasingly turned their attention to trying to explain this dramatic divide over what is factually true. And it wasn't long before they homed in on the role of conservative media in particular -- thus, a number of studies show that watching Fox News increases your risk of holding incorrect beliefs about the science of climate change."
