The Environmental Protection Agency announced the formal repeal of the 2009 Endangerment Finding this week, a move that effectively strips the federal government of its primary legal mechanism for regulating greenhouse gas emissions under the Clean Air Act. The decision has sparked immediate and intense backlash from environmental advocates, scientists, and industry leaders within the outdoor recreation sector. Protect Our Winters, a prominent advocacy group representing professional athletes, scientists, and outdoor enthusiasts, has responded by calling for the immediate resignation of EPA Administrator Lee Zeldin. The organization characterizes the repeal as a "dangerous new low" for an agency tasked with safeguarding public health and the environment, alleging that under Zeldin’s leadership, the EPA has transitioned from a regulatory watchdog into an active participant in the dismantling of foundational environmental protections.
The Significance of the Endangerment Finding
To understand the gravity of the current administrative shift, it is necessary to examine the legal and scientific history of the Endangerment Finding. Issued in 2009 following the landmark Supreme Court case Massachusetts v. EPA, the finding established a formal scientific determination that six greenhouse gases—carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride—threaten the public health and welfare of current and future generations.
This determination served as the legal bedrock for nearly every federal climate regulation enacted over the last 15 years. It mandated that the EPA take action to reduce pollution from vehicle tailpipes, power plants, and industrial facilities. By repealing this finding, the EPA is not merely changing a policy; it is attempting to negate the scientific consensus that links fossil fuel emissions to atmospheric warming and subsequent environmental degradation. Without the Endangerment Finding, the legal obligation for the federal government to mitigate climate change is significantly weakened, leaving existing air and water quality standards vulnerable to litigation and further deregulation.
A Chronology of Rapid Deregulation
The repeal of the Endangerment Finding follows a series of aggressive policy shifts that began in early 2025. Since taking office, Administrator Lee Zeldin has overseen a systematic effort to roll back environmental safeguards that have been in place for decades. The timeline of these actions reflects a coordinated strategy to prioritize the operational interests of the fossil fuel industry over established environmental science.
In January 2025, the EPA began a comprehensive review of the Waters of the United States (WOTUS) rule, seeking to narrow the definition of protected waterways and reduce federal oversight of wetlands and seasonal streams. By February, the agency moved to freeze the implementation of more stringent vehicle emission standards, arguing that such regulations imposed undue burdens on the automotive and energy sectors. In March, the administration announced a pause on the collection of methane leak data from oil and gas operations, citing a need to "reduce the paperwork burden" on energy producers.
The repeal of the Endangerment Finding represents the culmination of this deregulatory agenda. It provides the legal justification for the EPA to ignore the broader climate impacts of industrial projects, focusing instead on a much narrower interpretation of the agency’s statutory authority. This shift has prompted accusations from organizations like Protect Our Winters that the EPA has abandoned its core mission in favor of a "sweeping, coordinated effort" to benefit short-term economic interests at the expense of long-term ecological stability.
Scientific Data: The Reality of the Snow Drought
The policy shifts in Washington D.C. stand in stark contrast to the environmental data emerging from the American West. According to recent satellite imagery and ground-based scientific measurements, the western United States is currently experiencing a historic "snow drought." Snowpack levels across major mountain ranges, including the Sierras and the Rockies, are at a fraction of their historical averages for this time of year.
The primary driver of this phenomenon is not a lack of precipitation, but rather a significant increase in average winter temperatures. Data from the National Oceanic and Atmospheric Administration (NOAA) indicates that higher-than-average temperatures are causing precipitation to fall as rain rather than snow. Furthermore, when snow does fall, it is melting earlier in the season, disrupting the natural hydrologic cycle.
Mountain snowpack serves as the nation’s most critical natural reservoir. It stores water during the winter months and releases it slowly throughout the spring and summer, feeding the rivers and streams that sustain the country. The current lack of snowpack has immediate and dire implications:
- Water Scarcity: Low snowpack levels directly correlate with reduced water supplies for agriculture, particularly in states like California and Colorado that rely on meltwater for crop irrigation.
- Energy Production: Many western states depend on hydropower for a significant portion of their electricity. Reduced river flows threaten the stability of the power grid.
- Wildfire Risk: A thin snowpack leads to drier forests and soils earlier in the year, effectively lengthening the wildfire season and increasing the intensity of burns.
- Economic Loss: The outdoor recreation industry, which thrives on stable winter seasons, faces billions of dollars in potential losses as ski resorts and winter tourism hubs see shorter operational windows.
The Economic Impact on the Outdoor State
Protect Our Winters frequently refers to the "Outdoor State"—the 181 million Americans who participate in outdoor recreation annually. This demographic is a significant economic engine, contributing $1.2 trillion to the United States economy. This sector encompasses everything from manufacturing and retail to travel, hospitality, and local services in rural gateway communities.
The economic data highlights the vulnerability of this sector to climate volatility. In states like Montana, Utah, and Vermont, winter tourism is a primary source of tax revenue and employment. When "snow droughts" occur, the economic ripple effect is felt across the entire supply chain. Small business owners, from gear shop operators to restaurant staff, face financial instability.
Furthermore, the outdoor economy is often the backbone of Tribal nations and rural areas that have transitioned away from extractive industries toward sustainable tourism. The EPA’s recent actions, according to POW, constitute an "existential threat" to these communities. By dismantling the tools designed to address the root causes of climate change, the agency is perceived to be undermining the very environment that sustains a trillion-dollar industry.
Official Responses and Stakeholder Reactions
The call for Lee Zeldin’s resignation has resonated across various sectors, though the response remains polarized along political and industrial lines. Environmental groups have joined POW in their condemnation, with many preparing for a protracted legal battle.
"The EPA’s mission is clearly defined: to protect human health and the environment," said a spokesperson for a leading environmental law firm. "By rescinding the scientific basis for climate action, the agency is signaling that it no longer intends to fulfill its legal mandate. We expect these decisions to be challenged in federal court immediately."
Conversely, representatives from the fossil fuel and manufacturing sectors have largely welcomed the EPA’s new direction. Industry trade groups have argued that the Endangerment Finding was an example of "regulatory overreach" that stifled domestic energy production and increased costs for consumers. They contend that the repeal will provide much-needed "regulatory certainty" and allow for more rapid infrastructure development.
The EPA, for its part, has defended the Administrator’s actions. In a brief statement, an agency spokesperson noted that the EPA is focused on "rebalancing the scales" and ensuring that regulations are "consistent with the law as written by Congress." The statement did not directly address the call for Zeldin’s resignation but emphasized the administration’s commitment to "energy independence and economic growth."
Analysis of Broader Implications
The repeal of the Endangerment Finding and the subsequent call for the Administrator’s resignation mark a pivotal moment in American environmental policy. The implications of this shift extend far beyond the immediate political cycle.
First, the legal precedent being set could fundamentally alter how the Clean Air Act is applied. If the courts uphold the repeal, it may become significantly more difficult for any future administration to regulate carbon emissions without new, specific legislation from a divided Congress. This could lead to a decade of regulatory stagnation at a time when climate scientists warn that the window for meaningful action is closing.
Second, the "snow drought" and its associated impacts demonstrate the growing gap between federal policy and localized environmental reality. While the EPA moves toward deregulation, local and state governments are forced to deal with the tangible consequences of a warming climate, from water rationing to disaster management.
Finally, the mobilization of the "Outdoor State" suggests a shift in environmental advocacy. Organizations like Protect Our Winters are increasingly framing climate change not just as an ecological issue, but as a critical economic and public health concern. By highlighting the $1.2 trillion impact of the recreation economy, they are attempting to reach a broader audience and apply pressure on policymakers through the lens of economic stability.
As the legal and political battles over the EPA’s direction intensify, the environmental reality in the American West serves as a stark backdrop. The loss of the Endangerment Finding removes the primary legal shield against pollution, leaving the health of the planet and the stability of the economy in a state of heightened uncertainty. For the millions of Americans who depend on clean air, reliable water, and stable winters, the current trajectory of the EPA represents a fundamental challenge to their way of life.
