A Media Matters study found that most network nightly news programs this year are on track to offer no more coverage of global warming than they did in 2013. However, PBS NewsHour remains a notable exception, covering climate change more than any other network and interviewing the largest number of scientists on the topic.
During the first six months of 2014, PBS NewsHour produced more news that featured climate change than any other major network evening broadcast, continuing a trend that Media Matters identified in both 2012 and 2013. The program aired 28 stories that at least mentioned global warming, nearly as much as all coverage combined from ABC World News, CBS Evening News and NBC Nightly News during the same period, and four times the amount of coverage from ABC World News alone. Among all major nightly news programs, ABC by far offered its viewers the least coverage that gave any substantial mention of global warming, with only seven stories. While it is worth noting that NewsHour is an hour-long broadcast compared to the half hour broadcasts on the other networks, it nonetheless offered more than double the number of stories offered by its closest network news competitor, CBS Evening News.
ABC World News' lack of climate coverage so far this year correlates with its 2013 coverage when the program aired the fewest stories among all network nightly news shows, a flip in coverage from 2012 when the network was second only to PBS in such coverage.
Of the 28 stories that PBS NewsHour aired, 16 were segments focused on global warming. PBS NewsHour's coverage offered analysis of significant policy developments and major international reports, such as the Environmental Protection Agency's proposed carbon pollution standards and the Intergovernmental Panel on Climate Change's report that found climate change already has taken a toll on the planet and warned that food security and economic growth would be undermined if carbon pollution is not drastically cut. The program also connected unusual events, such as diseased starfish in the Pacific Northwest and coastal flooding on Alaska's North Slope, to the broader climate context.
More scientists were interviewed about climate change on PBS NewsHour than on any other network nightly news broadcast. During the first six months of the year, the NewsHour featured 14 scientists in its reports on global warming, nearly as many as the combined total of 16 scientists who appeared on all nightly news programs on ABC, CBS and NBC. For an issue firmly based in scientific research and evidence, PBS NewsHour relied heavily on scientists, only turning to six media figures and six politicians during the first half of 2014.
This report analyzes news coverage of "climate change" and "global warming" that aired on PBS NewsHour, ABC World News, CBS Evening News and NBC Nightly News between January 1, 2014, and June 30, 2014. Our analysis includes any segment devoted to climate change, as well as any substantial mention (more than one paragraph of a news transcript and/or or a definitive statement about climate change). Transcripts from Nexis and Media Matters' internal video archives, as well as the Internet Archive online database, were used to collect these stories.
