In 2014, PBS NewsHour provided far more climate change-related segments and interviewed far more climate scientists than the nightly news programs at ABC and NBC, while also outperforming CBS. Additionally, like CBS Evening News, PBS NewsHour managed to avoid airing any segments that provided a platform for climate science deniers, whereas NBC Nightly News and ABC's World News Tonight both featured a segment in which a guest either denied that climate change is occurring or questioned the scientific findings of the National Climate Assessment.
