Okay, it's probably not likely that they're doing it because of some moral imperative; the reasons are most likely connected to their bottom line. Still, it's interesting news that the largest public relations firm in the world (Edelman) has said that it will no longer do business with coal companies and climate change deniers because "they pose a threat to the company’s legitimacy and its bottom line." As the Guardian describes:

The exclusion of coal and climate denial, as well as fake front groups that oppose action on global warming, is outlined in internal communications obtained by the Guardian and confirmed by company executives. It signals an important shift in a company that reported earnings of $833m (£540m) and has played a critical role in shaping public opinion in the US and globally about climate change.

After two years of study Edelman concluded that:

. . . . coal producers and climate denial, as well as tactics such as greenwashing*, were high-risk.

“On climate denial and coal those are where we just said this is absolutely a no-go area,” Michael Stewart, the president and chief executive for Europe, who led the review, told the Guardian.

The company was also taking a stand against spreading doubt about climate change, and the use of fake front groups to influence elected officials, Stewart said.

Beyond Murray Energy, the Wheeling "newspapers" don't depend upon many outside sources for their misinformation about climate change. Even so, it's good to see that they'll have one less source for some of their bogus claims.

*The Oxford Dictionary describes "greenwash" as "disinformation disseminated by an organization so as to present an environmentally responsible public image."
