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.
Although it airs for twice as long as its broadcast network counterparts, PBS NewsHour's number of climate segments and scientists more than made up for this difference, particularly in comparison to ABC's World News Tonight. PBS NewsHour, which runs for 60 minutes, aired 45 reports last year that covered climate change. By comparison, CBS Evening News, NBC Nightly News, and ABC's World News Tonight, which are each 30 minute programs, aired 22, 14, and 11 climate-related reports in 2014, respectively. PBS NewsHour's 45 climate-related reports were a substantial increase over 2013, when the program aired 35 such reports.
PBS NewsHour also provided scientific perspectives in climate change stories more often than any of the other major networks, interviewing or quoting 27 scientists over the course of the year. In comparison, CBS Evening News and NBC Nightly News interviewed or quoted 11 and 7 scientists, respectively, while ABC's World News Tonight interviewed or quoted just two scientists.
Scientists lent their insight on a range of topics on PBS NewsHour, providing perspective on landmark reports on climate change, describing the impact of climate change on wildlife habitats, and illustrating how climate change is already having an impact on communities in places as disparate as Alaska and Florida. For example, in a two-part special on climate change's impacts in Alaska, PBS NewsHour interviewed paleoclimatologists, geophysicists, oceanographers, and ecologists to detail how climate change is threatening local wildlife and a centuries-old way of life for many Alaskans.
The recent announcement by NOAA and NASA that 2014 was the warmest year on record should serve as the starkest reminder yet that climate change is an issue deserving of mainstream media coverage. The networks' nightly news programs -- and ABC's World News Tonight in particular -- would do well to follow PBS NewsHour's lead by improving the quality and quantity of their climate change coverage.
