When science reporters write about, say, hormone therapy or drinking red wine, they report on studies that find that hormones or red wine can be good for you, as well as studies that suggest otherwise. Any science involving complex organisms is rarely black and white. When it comes to global warming, newspapers play up stories that reinforce the prevalent the-sky-is-falling belief that global warming is human-caused and catastrophic. But if a study or scientist does not portend the end of the world as we know it, it rarely rates as news.
