Media Matters searched transcripts in the Nexis and SnapStream databases for ABC’s Good Morning America, GMA3, World News Tonight, and This Week; CBS’ Mornings, Saturday Morning, Sunday Morning, Evening News, Weekend News, and Face the Nation; NBC’s Today, Today 3rd Hour, Sunday Today, Nightly News, and Meet the Press for any of the terms and any derivations of the terms “climate,” “global warming,” “global heating,” “global temperatures,” “warmer planet,” “warming planet,” “planet warms,” “warmer globe,” “warming globe,” “globe warms,” “rising temperatures,” “hotter temperatures,” “green new deal,” “emissions,” “greenhouse gases,” or “net zero” from January 1, 2024, through December 31, 2024.
We included any segment in which climate change was the stated topic of discussion, as well as news rundowns that included a substantial mention of climate change, which we defined as a paragraph or more of a news transcript or a block of uninterrupted speech by a host, anchor, or correspondent. We also included weather reports, which we defined as instances when climate change was mentioned in an extreme weather report by a meteorologist in front of a green screen. We also included instances of a guest mentioning climate change in a network correspondent segment if the context of the segment was clearly about a climate, energy, or environmental issue.
We timed identified segments using the SnapStream or Kinetiq video databases, or YouTube if a network posted the segment to that website.
We rounded all times to the nearest minute and all percentages to the nearest whole number.
