What is really corrupted is climate journalism.
Climate Journalism is Broken
A new paper reveals troubling biases
- Roger Pielke Jr. from The Honest Broker
In 2020, scholars published more than 50,000 peer-reviewed papers on climate change in almost 6,000 journals. A new
study by Marie-Elodie Perga and colleagues looks at how these papers were covered by news media and reveals some profound biases in coverage of climate. There are still some excellent journalists providing good coverage of climate, of course, but the overall patterns are troubling.
Let’s take a look at the numbers.
Of the 51,230 peer-reviewed papers on climate change published in 2020, Perga and colleagues found that only about 9% of them saw any media coverage, defined as a single mention in the paper’s
Altimetric score. About 2%, or ~1,000 papers, saw more than 20 mentions in the media. These “mediatized” papers are the focus of Perga’s paper.
The 2% of papers most covered by the media are disproportionately focused:
- at the global and continental scales;
- on the end of the 21st century;
- on the natural sciences and health;
- and come primarily from just 6 journals (3 from Science journals, 2 from Nature and PNAS).
I looked at their dataset and — as we might expect — RCP8.5 features prominently in many of the papers receiving the most media attention in 2020, including 4 of the top 5 most covered papers.
The biases are large. The paper reports that:
Overall, 56% of the top-100 mediatized papers on natural science report rate or magnitude of climate-driven changes at continental or global scales (40% being projections by the end-of-the-century), while those represent only 4% of the random paperset.
Reporting disproportionately deemphasized studies in the social and political sciences, economics, technology, engineering, energy and agriculture — these are all topics related to what might be done on climate change.
The authors conclude that as a result of these biases, news coverage is biased and the public is misinformed:
Thereby, a few articles get a lot of news mentions, limiting the diversity of information to which readers are exposed (Ortega, 2021). The selective sourcing of news media for high-profile journals and strong degree of co-mention in news outlets thereby come with a loss of disciplinary diversity of the research brought to public’s attention, with over-emphasis on natural science and health, while research findings produced on the social, economic, technological and energy-related aspects of climate change are curtailed back through the mediatization process. The selectivity is even found within the dominant natural science. Mediatized scientific publications are selectively concentrated on the worldwide magnitude of the current consequences of climate change, and projected risks by the end of the century for natural Earth components.
The authors hold a position that I do not — that the main purpose of media coverage of climate is to motivate people to act on climate, whatever that means. In my discussions of climate journalism with reporters (those that will speak to me) I often hear a similar view, that the purpose of climate journalism is advocacy for climate as a cause.
Indeed, the authors of the paper view themselves, alongside journalists, as collaborators in using communication to motivate “action”. Here is how they describe their work:
[C]limate communication research builds on social sciences to explore how and to what extent climate change is relayed and framed whilst developing optimized strategies and guidelines for transforming public engagement into actions.
This definition of “climate communication” is evocative of what almost a century ago political scientist
Harold Lasswell called, “the management of collective attitudes by the manipulation of significant symbols” — or political propaganda. If the idea that climate journalism is engaged in political propaganda seems uncomfortable, then try instead
advocacy journalism.
Although they may look and behave like modern media organizations, they are advocacy groups, and have an explicit agenda; they’re looking for impact. That agenda may coincide with the news, and they may use traditional journalistic techniques to advance it, but in most cases the larger goal of this work is in service of some kind of policy change or other action, and not information or the public record per se.
Climate journalism wasn’t always dominated by an advocacy agenda. More than a decade ago, I along with colleagues Ursula Rick and Max Boykoff evaluated
20 years of media coverage of sea level rise. We found overall media reporting on sea level rise to be highly consistent with the scientific literature and the assessment reports of the Intergovernmental Panel on Climate Change, summarized in the figures below.

We concluded, “accurate reporting on projections for sea level rise by 2100 demonstrates a bright spot at the interface of climate science and mass media.”
