The Environmental Protection Agency (EPA) issued a formal repeal of the 2009 Endangerment Finding on Monday, a move that effectively strips the federal government of its primary legal obligation to regulate greenhouse gas emissions under the Clean Air Act. The decision, spearheaded by EPA Administrator Lee Zeldin, represents a fundamental shift in American environmental policy and has prompted immediate calls for his resignation from climate advocacy groups, including the prominent non-profit Protect Our Winters (POW). This administrative action marks the first time in the agency’s history that a scientifically grounded determination of public health risk has been rescinded for the purpose of deregulating an entire industrial sector.
The Endangerment Finding is the cornerstone of federal climate authority. Established in 2009 following the landmark Supreme Court case Massachusetts v. EPA (2007), the finding concluded that six greenhouse gases—including carbon dioxide and methane—threaten the public health and welfare of current and future generations by contributing to climate change. By repealing this finding, the EPA has signaled that it no longer views the mitigation of carbon pollution as a statutory requirement, a stance that critics argue ignores decades of peer-reviewed climate science and ignores the mounting economic and physical tolls of a warming planet.
The Call for Resignation and the Charge of Mission Abandonment
Protect Our Winters, a coalition representing professional athletes, scientists, and business leaders within the $1.2 trillion outdoor recreation economy, issued a stinging rebuke of the agency’s direction. In an official statement, the organization called for the immediate resignation of Administrator Zeldin, accusing the EPA leadership of abandoning its core mission to protect human health and the environment. POW contends that the agency has transitioned from a regulatory body into an active facilitator for fossil fuel interests, prioritizing short-term corporate gains over the long-term stability of the American landscape.
The advocacy group highlights that the repeal of the Endangerment Finding is not an isolated incident but the culmination of a broader strategy observed since January 2025. This strategy has reportedly involved the systematic dismantling of clean air and water protections, the reduction of oversight on methane leaks, and the sidelining of agency scientists who have traditionally provided the data-driven foundation for environmental policy. For the "Outdoor State"—the 181 million Americans who participate in outdoor activities—the move is viewed as an existential threat to the resources that sustain their livelihoods and lifestyles.
Historical Context: The Rise and Fall of Climate Regulation
The trajectory of the Endangerment Finding is a reflection of the volatile nature of American environmental law. In 2007, the Supreme Court ruled in Massachusetts v. EPA that greenhouse gases fit the definition of "air pollutants" under the Clean Air Act. The court mandated that the EPA must determine whether these gases contribute to climate change that endangers public health. After an exhaustive review of scientific data, the EPA issued the 2009 finding, which provided the legal "hook" for every major climate regulation that followed, including the Clean Power Plan and fuel economy standards for vehicles.
The repeal in 2025 follows several years of legal maneuvering and political shifts. Proponents of the repeal argue that the 2009 finding was an example of administrative overreach that bypassed the legislative role of Congress. Under Administrator Zeldin’s leadership, the EPA has adopted a narrow interpretation of the Clean Air Act, often citing the "Major Questions Doctrine"—a legal principle recently favored by the Supreme Court that suggests agencies cannot make decisions of vast economic and political significance without explicit congressional authorization.
However, legal experts suggest that repealing a scientific finding is significantly more difficult than repealing a specific regulation. While a regulation can be replaced with an alternative policy, a finding of "endangerment" is based on physical evidence. To legally justify the repeal, the EPA must demonstrate that the scientific consensus has changed or that the original data was fundamentally flawed—a task that many atmospheric scientists claim is impossible given that global temperatures and atmospheric CO2 concentrations have only increased since 2009.
Scientific Indicators: The Reality of the "Snow Drought"
The EPA’s policy shift arrives at a moment of acute environmental stress in the American West. According to data from the National Resources Conservation Service (NRCS) and satellite imagery from NASA’s Earth Observatory, winter snowpack levels across the Sierra Nevada, the Cascades, and the Rocky Mountains are at historically low levels for this period of the year. This phenomenon, termed a "snow drought," is characterized not necessarily by a lack of precipitation, but by "warm-winter" conditions where precipitation falls as rain rather than snow.
Mountain snowpack serves as the West’s most vital reservoir, storing water during the winter and releasing it slowly during the spring and summer. This natural storage system is essential for:
- Agriculture: Providing consistent irrigation for the Central Valley of California and the high plains.
- Hydropower: Driving turbines that provide carbon-free electricity to millions of homes.
- Wildfire Mitigation: Maintaining fuel moisture levels to prevent the early onset of catastrophic fire seasons.
- Municipal Supply: Ensuring reliable drinking water for major metropolitan hubs including Denver, Phoenix, and Los Angeles.
Current measurements indicate that in several key basins, snow water equivalent (SWE) is tracking below 50% of the 30-year median. Scientific models attribute this trend directly to the warming of the troposphere caused by greenhouse gas accumulation—the very phenomenon the Endangerment Finding was designed to address. The loss of snowpack creates a feedback loop: less snow leads to drier soil, which leads to higher temperatures, which further reduces future snowfall.
Economic Implications for the Outdoor Recreation Sector
The outdoor recreation industry has emerged as one of the most vocal opponents of the EPA’s recent actions. According to the Bureau of Economic Analysis (BEA), the outdoor recreation economy accounts for approximately 2.2% of the United States’ Gross Domestic Product (GDP), generating over $1.2 trillion in annual economic output. This sector supports nearly 5 million jobs, many of which are located in rural communities that lack other diverse economic drivers.
When winter seasons are shortened or become unpredictable due to climate instability, the economic ripple effects are profound. Ski resorts face increased operational costs for snowmaking, while local hospitality businesses, gear retailers, and guide services see a direct drop in revenue. Protect Our Winters argues that by ignoring the science of climate change, the EPA is effectively undermining the stability of this massive economic engine. The organization emphasizes that for many Tribal nations and rural areas, the health of the environment is synonymous with economic survival.
Reaction from Industry and Environmental Legal Groups
The reaction to the repeal has been sharply divided along industrial and ideological lines. Representatives from the American Petroleum Institute (API) and other fossil fuel advocacy groups have historically argued that the Endangerment Finding created a "regulatory straightjacket" that stifled domestic energy production and increased costs for consumers. While some industry leaders have expressed support for the repeal as a means of ensuring "energy dominance," others have warned that constant shifts in the regulatory landscape create uncertainty that makes long-term capital investment difficult.
On the other side, a coalition of environmental law firms, including Earthjustice and the Sierra Club, have already announced their intention to challenge the repeal in federal court. They argue that the EPA’s move is "arbitrary and capricious," a legal standard used to overturn agency actions that are not based on a reasoned analysis of the facts. "The EPA cannot simply vote away the laws of physics," a spokesperson for a leading environmental legal group stated. "The science of 2025 is even more conclusive than the science of 2009. This repeal is a political maneuver masquerading as a policy shift."
The Path Forward: Legal Challenges and Administrative Accountability
The demand for Administrator Zeldin’s resignation marks a significant escalation in the friction between the federal government and the environmental advocacy community. While resignations of cabinet-level officials are rarely prompted by advocacy groups alone, the call serves as a rallying point for a broader movement of "The Outdoor State" to engage in the political process.
The legal battle over the Endangerment Finding is expected to reach the Supreme Court, where it will test the judiciary’s willingness to allow executive agencies to reverse long-standing scientific determinations. If the repeal stands, it will create a vacuum in federal climate authority, leaving states to implement their own "patchwork" of regulations, which may lead to further economic and legal complexities.
As the 2025 winter continues to break records for warmth and low snowpack, the disconnect between administrative policy and environmental reality remains a central point of contention. The EPA’s core mission—to protect human health and the environment—is now the subject of an intense national debate, with the future of the American landscape and the stability of its climate hanging in the balance. For the millions of Americans whose lives and livelihoods are tied to the health of the planet, the repeal of the Endangerment Finding is not merely a policy change; it is a fundamental realignment of the government’s relationship with the natural world.
