As Media Matters notes, despite Rupert Murdoch's 2007 pledge to improve reporting on climate science, the coverage at News Corp.'s Fox News and Wall Street Journal remains "overwhelmingly misleading," according to a new study by the Union of Concerned Scientists.

The Union of Concerned Scientists found: 

(The promised) improvement has not been achieved. A 2012 snapshot analysis shows that recent coverage of climate science in both outlets has been overwhelmingly misleading.

The analysis finds that the misleading citations include broad dismissals of human-caused climate change, rejections of climate science as a body of knowledge, and disparaging comments about individual scientists. Furthermore, much of this coverage denigrated climate science by either promoting distrust in scientists and scientific institutions or placing acceptance of climate change in an ideological, rather than fact-based, context.

Media Matters also notes:

These findings echo a 2011 study published in The International Journal Of Press/Politics which found that compared to other cable networks, "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." This is no surprise considering that Fox's Washington managing editor Bill Sammon directed Fox News reporters in 2009 to cast doubt on the basic fact that the planet has warmed. Indeed, Fox regularly distorts climate research, cherry-picks stories to cast doubt on climate change, and turns climate change into a punch line.
