The Trump administration’s stance on climate change has long been a subject of international debate and domestic policy shifts. Early in the administration, significant actions signaled a departure from previous federal climate efforts, including the withdrawal from the Paris climate agreement and a push to roll back environmental regulations. These moves set a controversial backdrop for subsequent discussions surrounding climate science.
Against this political landscape, the Department of Energy (DOE) released a report in July, titled “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate.” This document, which questioned the severity of global warming, quickly drew strong condemnation from the scientific community. It emerged as a focal point in the broader conversation about the role of science in policymaking.
What followed was an extraordinary public repudiation by dozens of the world’s leading climate researchers. Their collective response, a detailed and systematic dismantling of the DOE report’s findings, underscored the deep divisions between the administration’s narrative and the established scientific consensus on climate change. This article delves into the core aspects of this controversy, examining the DOE report’s claims, the scientific community’s robust rebuttal, and the broader implications for federal policy.
1. **The Energy Department’s Controversial Climate Report**The Department of Energy’s report, “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” was a pivotal document in the ongoing climate debate. Its publication in July was met with immediate scrutiny, not least because of the circumstances surrounding its creation. The White House had previously dismissed more than 400 scientists who were working on the sixth National Climate Assessment and had also shut down the website that housed prior assessments.
This hastily assembled report was authored by five researchers, who were selected by U.S. Energy Secretary Chris Wright. These individuals were described in the context as “well-known climate change contrarians,” a characterization that immediately raised concerns among mainstream scientists about the report’s potential objectivity and scientific rigor. The selection process itself suggested a predetermined direction for the findings.
According to department spokesman Ben Dietderich, the stated purpose of the report was “to restore an open and transparent dialogue around climate science.” However, many scientists argued that the report served a different function. They viewed it as an attempt to introduce doubt into well-established scientific understanding, thereby undermining the consensus on climate change and potentially justifying policy reversals.
Energy Secretary Chris Wright himself contributed a foreword to the report. In it, he acknowledged the reality of climate change but downplayed its effects. He stated that “misguided” policies on the issue had been based on fear, distorted facts, and exaggerated and incomplete information, setting a clear tone for the document’s overall argument against aggressive climate action.

2. **The Overwhelming Scientific Rebuttal**The release of the Energy Department’s report triggered an immediate and widespread reaction from the global scientific community. Dozens of the world’s leading climate researchers mobilized to publicly rebuke the document, initiating one of the strongest repudiations yet of the administration’s efforts to downplay climate change. This unified response highlighted the perceived urgency of addressing what scientists saw as fundamental misrepresentations.
More than 85 scientists, representing veterans in atmospheric science, physics, ecology, forecast modeling, and several other fields from universities, think tanks, and research institutions across the United States and abroad, contributed to a comprehensive rebuttal. This powerful collective statement denounced the DOE’s July report as “biased, error-ridden and unfit for guiding policy.” Their critique was submitted as a public comment in the Federal Register, alongside more than 2,400 other comments.
The critical review, a substantial 459-page document, was a grassroots effort organized initially by Andrew Dessler, a professor of atmospheric sciences at Texas A&M University. He posted on the social media site BlueSky, asking if anyone was considering a coordinated response. This led to a robust effort to review and reply to each section of the DOE report, demonstrating the scientific community’s strong commitment to accuracy and peer review.
Key figures involved in the rebuttal underscored its significance. Robert Kopp, a distinguished professor in the Department of Earth & Planetary Sciences at Rutgers University and one of the authors, stated that “The more than 85 volunteer expert reviewers found that DOE’s committee of five produced a report that is not scientifically credible.” This assessment echoed sentiments across the scientific spectrum.
Further adding weight to the critique, a separate public comment was submitted by the Union of Concerned Scientists, a nonprofit representing over 21,000 scientists. This group decried the department’s report as “deeply flawed” and rife with “anti-science content.” They described it as “a staggering affront to the public to see such a flawed product put forward as an official U.S. Government document.”

3. **Questionable Conclusions on Economic Impact**Among its most controversial conclusions, the Energy Department report asserted a mitigated view of the economic consequences of global warming. It determined that carbon dioxide-induced warming “might be less damaging economically than commonly believed,” directly challenging prevailing scientific and economic assessments regarding climate change impacts. This claim suggested a downplay of potential financial risks associated with a warming planet.
Building on this perspective, the report also suggested that “aggressive mitigation policies”—specifically those designed to curb the use of fossil fuels— “could prove more detrimental than beneficial.” This argument provided a potential economic justification for the administration’s stated objectives of rolling back environmental regulations and promoting fossil fuel production, framing climate action as an economic burden rather than an investment.
Energy Secretary Chris Wright, in his foreword, articulated a view that such policies were “misguided” and driven by “fear, distorted facts and exaggerated and incomplete information.” This positioned the administration’s report as a corrective to what it presented as an overly alarmist and unsubstantiated consensus on climate’s economic fallout. It aimed to shift the perception of the costs and benefits of climate action.
However, scientists involved in the rebuttal strongly countered these economic assertions. Robert Kopp of Rutgers emphasized that the report’s strategy was “about emphasizing the uncertainty — things might not be as bad as we think — while ignoring the potential that things could be much worse than we think.” This highlights a perceived imbalance in the report’s risk assessment, selectively focusing on less dire scenarios while omitting potentially more severe outcomes.
In fact, many climate scientists have noted that actual climate change impacts have often been more severe than projected. The context states that “climate change has been outpacing many scientific projections, which tend to be conservative, given their reliance on consensus.” This observation directly contradicts the report’s underlying premise that existing climate assessments might be overly pessimistic regarding economic and environmental consequences.
4. **Flawed Scientific Methodology and Peer Review**A central pillar of the scientific community’s critique of the Energy Department report was its profound lack of rigorous scientific methodology and adherence to standard peer review processes. Scientists widely condemned the document, asserting that it “fails to adequately represent the current scientific understanding of climate change” and that it was “biased, error-ridden and unfit for guiding policy.” Such foundational flaws severely undermined its credibility.
Critics specifically highlighted that the report “misrepresents evidence, relies on discredited research and fails to follow the peer review process typically expected of rigorous scientific assessments, among other concerns.” The absence of a transparent and robust external peer review was a significant point of contention, as it is a cornerstone of scientific validation and quality control. This omission raised immediate questions about the veracity of its conclusions.
Robert Kopp, a lead author of the critical review, unequivocally stated that the DOE report was “not scientifically credible.” He explained that the panel of over 85 expert reviewers, all volunteers, concluded that the committee of five authors chosen by the DOE had produced a document that did not meet scientific standards. This judgment was a direct challenge to the report’s legitimacy as a scientific assessment.
Andrew Dessler further elaborated on the methodological deficiencies, asserting that the report “makes a mockery of science.” He detailed its reliance on “ideas that were rejected long ago, supported by misrepresentations of the body of scientific knowledge, omissions of important facts, arm waving, anecdotes and confirmation bias.” Dessler compared the report to a “badly written blog post,” suggesting a severe lack of academic rigor typically associated with federal scientific documents.
While a DOE spokesperson claimed the report underwent internal review “amongst DOE’s scientific research community” and by “policy experts from the Office of Science and National Labs,” this was insufficient for the broader scientific community. Dessler contended that the arguments put forward in the working group document “would never survive a peer review in a scientific journal,” implying that the internal review process did not meet the rigorous standards necessary for such a consequential report.
5. **Cherry-Picking Data and Misrepresenting Research**A pervasive criticism leveled against the Energy Department report was its consistent practice of “cherry-picking” data and selectively citing scientific literature to support its predetermined conclusions. This strategy was identified by numerous scientists as a fundamental flaw, undermining the report’s objectivity and scientific integrity. The aim, critics argued, was not a comprehensive scientific review but a targeted narrative.
The summary of the scientists’ comments explicitly stated that the working group report “exhibits pervasive problems with misrepresentation and selective citation of the scientific literature, cherry-picking of data, and faulty or absent statistics.” This highlighted a pattern of biased presentation rather than a balanced assessment of available evidence. The report, in essence, constructed its arguments by carefully selecting what to include and what to omit.
An Associated Press survey of 64 scientists found that the most common critique was that the administration’s reports “ignored, twisted or cherry-picked information to manufacture doubt about the severity and threat of climate change.” A significant 19 of these scientists specifically used variations of the phrase “cherry pick” to describe citations within the administration’s reports, underscoring the prevalence of this practice.
Rebecca Neumann, a researcher at the University of Washington who participated in the rebuttal, contextualized this approach within the evolving landscape of climate denial. She stated, “As outright denial of climate change becomes less tenable, the new approach is to downplay its dangers and exaggerate its upsides.” This suggests that cherry-picking is a strategic shift to maintain skepticism about climate action, moving from outright denial to a more nuanced form of minimization.
Andrew Dessler further explained this tactic, noting that the government’s version often deployed a “scientific ‘kernel of truth,’ taken out of context, to make its arguments seem credible.” This manipulation of factual information, by removing it from its broader scientific context, created a veneer of legitimacy for claims that were otherwise scientifically unsupported or misleading in their implications.
6. **Broader Trump Administration Climate Policy Context**The Department of Energy’s controversial report did not exist in a vacuum but was rather one component of a broader, aggressive agenda pursued by the Trump administration concerning climate and environmental policy. The administration had been outspoken in its skepticism of climate change, consistently acting to roll back environmental protections and promote fossil fuel industries. This context is crucial to understanding the report’s purpose and impact.
In March, EPA Administrator Lee Zeldin announced the agency’s plans to roll back more than 30 environmental regulations. These regulations, he stated, were stifling American energy production and driving up costs for consumers. Zeldin’s provocative declaration, “We are driving a dagger straight into the heart of the climate change religion,” clearly articulated the administration’s adversarial stance towards established climate science and policy.
Furthermore, President Trump initiated the withdrawal of the U.S. from the Paris climate agreement, a landmark international accord aimed at reducing global greenhouse gas emissions. Following this, the administration championed the production of fossil fuels such as oil, gas, and coal. These actions directly contradicted the scientific consensus that these fuels contribute to climate change by releasing carbon dioxide that traps heat in the atmosphere.
Parallel to these policy shifts, the administration had been halting clean-energy projects that were fully permitted, under contract, and even under construction. This further illustrated a systemic effort to prioritize traditional energy sources over renewable alternatives, despite growing calls for transitioning to cleaner energy. These actions collectively signaled a clear direction in federal energy and environmental policy.
Crucially, the Environmental Protection Agency (EPA) explicitly leveraged the Energy Department report in its hotly contested proposal to repeal the endangerment finding. This landmark 2009 determination affirmed that planet-warming greenhouse gases pose a threat to human health and the environment, serving as the basis of many federal climate efforts. The report thus provided a purported scientific justification for a significant policy reversal with wide-ranging implications for environmental regulation in the United States.

7. **Distorting Core Climate Data: Arctic Sea Ice and Sea Level Rise**The Department of Energy report drew sharp criticism for presenting specific numerical inaccuracies regarding vital climate indicators. One notable example cited by scientists involved Arctic sea ice, which the report claimed had declined by approximately 5% since 1980. This figure was accurate for Antarctica, but profoundly misleading for the Arctic, where the actual decline during that period exceeded 40%.
This discrepancy highlighted a significant misrepresentation of established data, aiming to minimize the perceived impact of global warming. Such selective use of statistics was a key concern for the more than 85 scientists who authored the comprehensive rebuttal, underscoring a pattern of bias rather than an accurate scientific assessment.
Another critical area of distortion involved sea-level rise. The DOE report stated that U.S. tidal gauge readings revealed “no obvious acceleration” of sea-level rise. However, critics quickly pointed out that the report had selectively chosen only five tidal gauges to support this claim, while ignoring a wide body of findings to the contrary that clearly indicate an acceleration of sea-level rise.
Such specific omissions and mischaracterizations of fundamental climate data contributed to the overall impression that the report was designed to downplay the severity of climate change. The scientific community emphasized that these actions undermined the document’s credibility as a guide for policy, showcasing a deliberate intent to obscure widely accepted scientific realities.
8. **Misrepresenting Research on Economic and Agricultural Impacts**The Energy Department report also presented conclusions regarding economic and agricultural impacts that scientists contended were based on misrepresentations of existing research. For instance, the report highlighted that carbon dioxide is a greenhouse gas that aids plant growth, suggesting that increased CO2 could improve agricultural yields. However, it selectively sidestepped the negative and often severe impacts of global warming on plant life, such as extreme heat, drought, wildfires, and floods, which counteract any potential benefits.
Additionally, the report was criticized for misusing the work of Antonio Gasparrini, a professor of epidemiology. The report cited his studies to support the statement that deaths caused by cold weather exceed those caused by heat. While Gasparrini confirmed this specific fact, he stated that the report ignored the crucial context that climate change is actively increasing heat-related deaths, and at a greater rate than it would prevent deaths from cold.
Another instance of misrepresentation involved Kristie Ebi, a global health professor. The report highlighted her work as proof that dietary supplements could help combat nutrient loss from plants in a warmer world. Dr. Ebi, however, explicitly stated that her research did not make such a claim, indicating a direct fabrication or significant distortion of her findings to fit the report’s predetermined narrative.
Rebecca Neumann, a researcher at the University of Washington involved in the rebuttal, contextualized this approach within an evolving strategy: “As outright denial of climate change becomes less tenable, the new approach is to downplay its dangers and exaggerate its upsides.” This pattern of selectively presenting information to minimize threats and emphasize perceived benefits was a consistent theme of the scientific community’s critique.
9. **Fabricating Scientific Support: Fictional Studies and Misapplied Research**Beyond misinterpreting existing research, the Department of Energy report exhibited instances of fabricating scientific support and misapplying studies, further eroding its scientific credibility. One egregious example highlighted by the scientific rebuttal was the report’s citation of a non-existent 2023 paper when discussing risks from climate change. The report even included a link that, upon inspection, led to a completely different paper which, ironically, concluded that nations should address climate change due to its damaging consequences.
Several climate scientists whose research was supposedly cited in the Trump report came forward to state that their work was misused or misrepresented. Zeke Hausfather, a climate scientist, noted that the report pulled a single figure from his work on climate modeling to construct a case that models are overly pessimistic. Hausfather clarified that his research actually concluded that climate models have performed quite well, calling the government’s process a “farce.”
Similarly, French economist Francois Bareille’s work on climate-related crop losses in French agriculture was cited in the administration’s reports. However, Bareille stated that his specific regional findings were wrongly generalized to other regions, indicating an inappropriate application of his specialized research to broader contexts.
Pamela D. McElwee, a professor of human ecology at Rutgers University, reviewed a section claiming technological advances and wealth would protect communities from climate impacts. She called the report “absolute sloppiness” for failing to consider future scenarios and the true cost of climate disasters, despite citing an example of New Orleans after Hurricane Katrina. These examples collectively illustrate a report that not only twisted facts but actively constructed a misleading facade of scientific backing.
10. **The Strategic Goal: Manufacturing Uncertainty and Muddling the Waters**The pervasive flaws in the Department of Energy report, from numerical errors to misrepresentations of research, were seen by many scientists as part of a deliberate strategy to “manufacture scientific uncertainty where it does not exist.” Andrew Dessler, who organized the scientific rebuttal, emphasized that the goal was not to win a scientific debate, but rather to create the *perception* of one.
This tactic drew direct comparisons to historical efforts by the tobacco industry to sow doubt about the health links between smoking and cancer. As Dessler articulated, “All they’re trying to do is muddy the waters here, create this idea that there’s a debate, and then the government will use that to roll back regulations.” This suggests a political objective overshadowing genuine scientific inquiry.
Dessler further described the report as making “a mockery of science,” likening it to a “badly written blog post.” Despite its lack of academic rigor, he stressed that it demanded a robust response because “This is something coming out from the federal government that the federal government could conceivably use to make policy.” The concern was not merely academic but deeply practical regarding its potential policy implications.
Ultimately, the scientific community interpreted the administration’s actions as an attempt to “rewrite the rules of science.” Dessler contended that the arguments presented in the working group document “would never survive a peer review in a scientific journal.” He suggested the administration sought to bypass the established scientific process, trying to find a “venue where they can win” by creating an alternative narrative for policy justification.
11. **The Federal Imprimatur: Using the Report for Policy Reversal**Perhaps the most significant consequence of the Department of Energy’s report was its explicit use by the Environmental Protection Agency (EPA) to justify a major policy reversal. The EPA leveraged the DOE report in its hotly contested proposal to repeal the endangerment finding, a landmark 2009 determination. This finding had affirmed that planet-warming greenhouse gases pose a threat to human health and the environment, serving as the foundational basis for many federal climate efforts.
The repeal of the endangerment finding carries immense implications for environmental regulation in the United States. If successful, it could lead to the elimination of numerous laws and rules aimed at reducing or restricting greenhouse gas emissions, including regulations for vehicles, power plants, and the oil and gas industry. This effectively undoes years of established environmental policy based on scientific consensus.
Climate denialists had long expressed a desire to bestow the “imprimatur of the federal government on research that runs counter to accepted climate science.” The DOE report provided this official sanction, potentially enhancing their influence with Congress and strengthening their ability to legally challenge existing climate regulations. The report served as a purported scientific justification for a political agenda to dismantle environmental protections.
Jim Rossi, a professor specializing in energy law at Vanderbilt University, commented on the gravity of this situation. He noted that the DOE report was “significantly flimsier” than what would typically be used to support federal policies or reverse them. Rossi emphasized that while dissenting viewpoints are not inherently problematic, evidence used to reverse a policy decision “ought to be at least as strong as the factual record and science that supported the decision in the first place,” a standard the DOE report evidently failed to meet.
12. **Broadening the Rejection: Support from Leading Scientific Organizations**The immediate and strong rebuke from individual scientists was significantly amplified by major scientific organizations, lending further weight to the condemnation of the Department of Energy report. The Union of Concerned Scientists, a nonprofit representing over 21,000 scientists, submitted a separate public comment that decried the DOE’s report as “deeply flawed” and rife with “anti-science content.” They described it as “a staggering affront to the public to see such a flawed product put forward as an official U.S. Government document.”
Adding to the institutional critique, the American Meteorological Society (AMS), a premier climate science organization representing weather and climate experts, also published a statement identifying “foundational flaws” in the report. The AMS criticized the report for “selectively emphasizing a small set of unrepresentative findings,” particularly those that might appear beneficial superficially, and for “cherry picking” to downplay harmful scientific findings. The society pointed out that the arguments presented in the DOE report were not new and had been previously considered and largely rejected by the broader scientific community.
Further demonstrating the collective resolve to uphold scientific integrity, the National Academy of Sciences, a distinguished collection of private, nonprofit institutions dedicated to providing independent analysis, began preparing a fast-tracked special report. This report was focused on the latest evidence concerning whether greenhouse gas emissions endanger public health, signaling a high-level institutional effort to reaffirm established climate science against politically motivated challenges.
Kim Cobb, a professor of Earth, environmental, and planetary sciences at Brown University and co-author of sections of the rebuttal, underscored the importance of this unified scientific stance. She articulated the broader concern that turning away from sound science, not just in climate but in other fields, would incur “grave costs.” The concerted response from individual researchers and prominent scientific bodies alike highlighted a steadfast commitment to defending the integrity of climate science against what they perceived as an unprecedented assault on its foundational principles.
The widespread and detailed repudiation of the Department of Energy’s climate report by hundreds of scientists and leading scientific organizations stands as a powerful testament to the scientific community’s unwavering commitment to accuracy and evidence-based policy. In the face of political attempts to sow doubt and justify deregulation, the collective voice of science has affirmed that the realities of human-caused climate change are well-established and demand urgent, credible action.
