On December 16th, the Salt Lake Tribune published an article titled, “Researchers warned the Great Salt Lake could dry up in 5 years. Now, they’re being mocked.” It was based on a three-part series on Utah Public Radio’s UnDisciplined podcast titled, “The seagull and the snowpocalypse.” I love criticisms, hot takes, and frank discussions, and I found the series to be engaging. Unfortunatley, there are multiple ethical, journalistic, and scientific issues in both the Tribune and UPR pieces. Given that our report was the target of their criticisms, this open letter likely seems like me being defensive about our report, but please read on. Our report took a lot of heat, which is understandable and positive, and I haven't felt the need to respond publicly about anything until now.
- Dr. LaPlante never discloses that he is the lead author of the single study that the series is based on 1. The study has its merits, but it is speculative, published in a low-impact journal, and contrary to the consensus on most points. Regardless of the strength of the study, representing his own scholarship as an independent study raises ethical and journalistic questions.
- The series states multiple times that the decline of Great Salt Lake is primarily caused by climate change, which has been disproven by multiple peer-reviewed studies and state reports. Consumptive water use is estimated to account for 67-73% of the lake’s decline, with climate change accounting for only 8-11% 2. Every episode of the podcast, especially the final one, emphasizes climate change as the primary driver of the decline of the lake, or at least equal to consumptive water use.
- The conclusion of the series is that there is nothing we can do, but it doesn’t really matter because the lake is unlikely to dry up before the end of the century. This is false scientifically and not supported even by the statistics in LaPlante’s study, which relies on extrapolating correlative relationships between historical groundwater and lake level.
- Dr. LaPlante creates a false sense of security about the likelihood of returning to or dropping below 2022 levels, claiming that it is highly unlikely that the lake drops below that level until several decades from now. As of November, the lake is at its 2021 level 3, and despite important legislative and management efforts, there has not been a measurable increase in water flow from changes in human behavior 4.
- The series misrepresents the content of our 2023 study and the interview the study authors engaged in by decontextualizing the five-year scenario and disregarding the rest of the content. In effect Dr. LaPlante and the other contributors are engaging in the kind of oversimplified journalism that they claim to take to task with this series.
I hope that the authors, Utah Public Radio, and the Salt Lake Tribune will consider these criticisms as they decide whether to keep the content up or publish the forthcoming parts of the series.
Sincerely,
Ben Abbott
Issues:
- Journalistic ethics and errors
- Matthew LaPlante never discloses that the study he bases the series off of and repeatedly cites simply as a “peer reviewed article” is his own work, not an independent piece of research (A Nuclear Bomb or just a Joke?). His article is published in a low-impact journal, and it does not reflect the consensus view, making it likely unreliable. It uses a downscaled climate model and a correlative relationship between groundwater and lake level to extrapolate potential future lake behavior, neglecting the fact that both of these factors are impacted by lurking variables (consumptive water use, weather, and climate). More generally, this is classic “one-study syndrome” where reporting focuses on a single study without comparing it to the current consensus. This is particularly problematic because Dr. LaPlante’s lack of disclosure of his participation in the study and misrepresentation of the paper in both the written piece and podcasts (details below).
- An extended quote by Bonnie Baxter is attributed to Lynn de Freitas:
- “I got asked a lot, ‘Is it really five years?’” said Lynn de Freitas, a co-author of the report and the executive director of the nonprofit group Friends of Great Salt Lake, which was founded in 1994 to advocate for the lake’s preservation. “And the timeline is interesting, because it’s actually from that trajectory downward that was extrapolated from the data. You could follow the line, how it was going down, and just continue the line and ask the question: ‘How long before we get here?’ And that was five years.”
- Scientific inaccuracies
- Climate trends are mischaracterized, claiming that wet and dry periods occur at regular intervals since we have records. This is contradicted by the broader literature, which has described the “Millennial Drought” extensively, attributing a portion of the nonstationarity to climate change5,6. Overall precipitation and runoff have decreased, but human water use dominates the lake level, likely creating a 15’ differential between where it would be naturally and where it is today7. The claim of regular intervals of drought is also contradicted by Dr. LaPlante’s own paper, which identifies multiple decade-or longer periods of extreme low flows where the lake may have reached similar levels over the past several hundred years.
- In both the podcast and his peer-reviewed paper, Dr. LaPlante claims that climate is as least as important or more important than consumptive water use. For example, he writes that it is only a possibility that “human diversion of the major streams that feed the lake may be a substantial contributing factor in the lake’s decline.” Multiple studies have demonstrated the dominance of local water use, which accounts for around 80% of the decline of saline lakes globally and 67-73% in the specific case of Great Salt Lake8,9. In fact, the misattribution of the decline of Great Salt Lake to climate change has specifically been addressed in the scientific literature as a phenomenon called “climatization” and described as a major threat to the Earth sciences because it undermines rigorous attribution of environmental problems and potentially undermines appetite to act locally10–12.
- There is misrepresentation of Dr. Ibrahim Mohammed’s research. The series says that his work supports the claims that climate is primarily responsible for the decline of the lake and that the lake is resilient to desiccation in the future because of salinity-evaporation stabilizing feedbacks. In fact, Dr. Mohammed’s work concludes that the lake is much more sensitive to consumptive water use than changes in evaporation, and that human water use can and has overcome the stabilizing salinity feedback13,14.
- Mischaracterization of the report (and the interview with Bonnie Baxter, Lynn De Freitas, and Ben Abbott)
- The series disregards content of the report (other executive summary points and virtually the whole body of the report), only focusing on the five-year scenario, which itself is mischaracterized. The report never claims that GSL will be completely desiccated within five years. The executive summary states, “If this loss rate continues, the lake as we know it is on track to disappear in five years.” As specified in the report and reiterated to the producer of the podcast when they interviewed us, we were referring to the lake’s overall function, which was already collapsing in 2022. At that time, the lake was only months away from salinity thresholds where neither the brine shrimp or brine flies could reproduce. Dr. LaPlante’s paper similarly only takes the strawman argument of total lake desiccation rather than the functional collapse described throughout the report.
