DOE Report Upends Climate Alarmism: CO2 Not the Villain We Were Told

The intellectual foundation of modern climate policy rests on a shaky assumption: that anthropogenic carbon dioxide emissions, left unchecked, will wreak unmanageable havoc on the Earth’s climate and economy, and that radical mitigation is the only path forward. This assumption has been treated not as hypothesis but dogma, one that brooks no dissent. Yet, on July 29, 2025, the Department of Energy (DOE) disrupted this orthodoxy with a quietly released but tectonic report, A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate. Its findings deserve our undivided attention.

Developed by the 2025 Climate Working Group under Energy Secretary Chris Wright, this report evaluates the empirical record, existing literature, and widely cited models of climate change and its impact. It issues a sober verdict: the harms of CO2-induced warming are overstated, the benefits underreported, and the United States' costly mitigation policies amount to symbolic gestures with virtually no measurable effect on global climate trajectories.

Let us pause on that last point. The United States is often urged to lead the world in climate action, regardless of cost or efficacy. But as the DOE report makes clear, our domestic efforts will have “undetectably small direct impacts on the global climate” and whatever marginal effects might accrue would only unfold over centuries. That is not policy, that is performance art.

The report’s challenge to prevailing climate dogma is not confined to global impact. Its most devastating conclusion lies in the economic analysis. CO2-induced warming, it asserts, is less damaging economically than conventionally believed. Why? For one, the benefits of carbon dioxide, especially in enhanced plant growth and agricultural productivity, have been systematically minimized. Atmospheric enrichment with CO2, the molecule that every leaf on Earth craves, has produced tangible greening of the planet, as satellite data has repeatedly confirmed. The report notes that elevated CO2 levels are associated with longer growing seasons, higher crop yields, and improved drought resistance.

To this, some will object: but what about the disasters? The hurricanes, the wildfires, the floods and droughts? Here, too, the DOE report punctures myth with data. Trends in extreme weather, whether hurricanes, tornadoes, or droughts, do not show a statistically significant increase in frequency or intensity in the US. The belief that climate change is driving more disasters is not borne out by the nation’s own historical record. The pattern is familiar: catastrophic headlines dominate the news cycle, but peer-reviewed long-term data often reveals no clear signal.

What the report urges us to reconsider is not science per se, but scientific selectivity. Which studies are emphasized, which outcomes are modeled, which scenarios are dramatized, these are not neutral choices. They reflect a politicization of climate discourse that has ossified around worst-case predictions. The DOE’s panel of independent scientists, drawing on physical science, climate modeling, economics, and academic research, concludes that aggressive mitigation strategies could be more harmful than beneficial.

Why? Because such policies incur massive economic costs today in exchange for theoretical benefits centuries in the future. The social cost of carbon, a number derived from notoriously elastic models, is used to justify expansive regulation and taxation. But the opportunity cost of mitigation is rarely tallied. The DOE report points to harms from these policies: deindustrialization, energy poverty, manufacturing flight, and disproportionate burdens on low-income families. In seeking to avert a hypothetical crisis tomorrow, we are creating a very real one today.

Consider Germany’s “Energiewende” experiment. Once celebrated as a model for renewable transition, it has left the country with some of the highest energy prices in the world, increased coal usage, and stagnating industrial output. That is not progress; that is regression clad in moral virtue.

The DOE report does not deny climate change. Rather, it questions whether the response, especially by the US, acting alone, is rational, proportional, or effective. A sound policy approach would weigh benefits against costs, factor uncertainty, and consider adaptation as a co-equal strategy. It would recognize that prosperity, technological advancement, and institutional resilience are the most reliable defenses against climate risk.

And what of the global context? China emits more CO2 than the US and EU combined, and continues to expand its coal fleet. India, rightly prioritizing growth and poverty alleviation, follows a similar path. Even under idealized global mitigation scenarios, temperature effects remain marginal for decades. If the goal is climate stability, US policy must reckon with this reality.

There is a deeper lesson here about humility. Climate models are not oracles, and long-range forecasts are fraught with uncertainties. The Intergovernmental Panel on Climate Change (IPCC) itself acknowledges the "deep uncertainty" surrounding cloud feedbacks, ocean cycles, and aerosol effects. Yet policymakers cling to worst-case models like RCP8.5 as if they were certainties. The DOE report reminds us that science, when honest, acknowledges what it does not know.

The economic modeling is equally uncertain. How do we quantify the benefit of a slightly cooler planet in 2150? How do we discount the loss of economic growth, technological progress, and human well-being between now and then? These are not simple equations. They are philosophical judgments smuggled into spreadsheets.

One need not reject the premise of climate change to accept the report’s conclusion. One need only accept that climate risk exists alongside other risks—economic, geopolitical, social. A rational society does not bankrupt itself to prevent a hypothetical future while ignoring the very real suffering of its present.

This report ought to serve as a corrective. It does not deny that CO2 has climatic effects, but it insists we view those effects in context. It challenges the catechism of decarbonization as the sole moral and practical imperative. It urges policymakers to consider adaptation, resilience, and economic growth as indispensable tools in managing a changing climate.

To those who regard such conclusions as heresy, consider this: Truth does not fear scrutiny. If the consensus is as solid as claimed, it should welcome a challenge from a panel of independent scientists operating under a federal mandate. That is how science progresses, not through suppression, but through argument.

The American people deserve more than theatrical virtue-signaling. They deserve climate policies rooted in realism, not alarmism; in cost-benefit analysis, not eschatology. The DOE report offers a roadmap. We would do well to follow it.
