NewsBusters' Scott Whitlock has claimed that ABC World News “hid the identity of a global warming activist” whose commentary was played during ABC's newscast on Monday:

The journalist featured a clip of Heidi Cullen, who ABC simply labeled as a “climatologist.” She announced, “When you crank up the heat, when you globally warm the planet, you're going to see more extreme events.”

Yet, Cullen is also the communications director for Climate Central, a group dedicated to “helping mainstream Americans understand how climate change connects to them, and arming our audiences with the knowledge they need to make informed decisions about their future.”

Avila made no mention of her advocacy on this topic. Yet, on May 23, 2011, in another World News piece by Avila, the network did identify Cullen's connection. (She also touted climate change as host of a now-defunct show on the Weather Channel.)

But this is how ABC World News identified Heidi Cullen during the report as it was broadcast on DirecTV in Washington, D.C (note the upper left-hand corner of the screen image):

UPDATE: NewsBusters subsequently corrected its blog post:

[08-17-11 Correction: ABC did have the words “Climate Central” in the upper left-hand corner of the screen. Though, the network did not offer any explanation of the group's advocacy.]
