OK, we are not going to go on about this, but you may remember that NPR national laid off all but one of its environmental reporters back in October 2014. We only knew about this because the Pulitzer-winning InsideClimate News cared enough about environmental journalism to report it.
So this fall reporting by InsideClimate News, the Los Angeles Times, and others documented that Exxon knew decades ago that anthropogenic climate change was real -- but funded a campaign of denial. The story only grew as Democrats (all three presidential hopefuls) and others called for a RICO investigation (like the one that caught Big Tobacco). A lot of media covered it.
But not NPR. Some NPR listeners complained. NPR's Ombud Elizabeth Jensen looked into it and posted "Edith Chapin, NPR's executive editor, told me by email that she believes NPR dropped the ball."
