LIVE at 1 p.m. ET: The Endangerment Finding Is Dead. Here’s Why It Matters — The Climate Realism Show #190

The repeal of the Endangerment Finding (EF) on February 12, 2026, marks the most significant shift in U.S. environmental policy in decades. While it effectively “unplugs” the federal government’s primary mandate to regulate greenhouse gases (GHGs) under the Clean Air Act, the momentum of climate-related action is unlikely to vanish.
Instead of disappearing, the movement is shifting into a “guerilla warfare” phase characterized by aggressive state-level mandates and a new wave of high-stakes litigation. Here is the case for why “climate alarmism”—or at least the regulatory and legal framework surrounding it—will persist.
1. The “State-Led” Backstop
The removal of federal authority does not nullify state authority. In fact, it often triggers it. Blue states have already begun constructing a “regulatory wall” to bypass federal rollbacks:
Waivers and Independent Standards: California, joined by a coalition of over 20 states representing more than 50% of the U.S. population, continues to enforce its own vehicle emission standards. By the time federal repeals take full effect, many manufacturers will already have moved toward these state-mandated benchmarks to maintain access to these massive markets.
State “Green Amendments”: States like New York, Pennsylvania, and Montana have “Green Amendments” in their constitutions that grant citizens a right to a clean environment. These are being used to sue for climate action at the state level, where federal deregulation holds no sway.
Interstate Compacts: Groups like the Regional Greenhouse Gas Initiative (RGGI) continue to operate cap-and-trade programs for power plants, effectively maintaining a carbon price in the Northeast and Mid-Atlantic regardless of the EPA’s stance.
2. The Rise of “State Tort” Litigation
Ironically, repealing the EF may have opened a legal “Pandora’s Box.” Previously, federal law often preempted (blocked) state-level lawsuits against oil companies because the EPA was already “handling” the issue via the EF.
Jurisdictional Shift: Without a federal regulatory framework, the argument for federal preemption weakens. Legal experts suggest that 2026 will see an explosion of state-level tort claims (nuisance, failure to warn, and consumer deception) against energy companies.
Current Precedent: In early 2026, California and Hawaii courts have already allowed climate-related lawsuits against “Big Oil” to proceed, rejecting industry attempts to dismiss them. These cases seek billions in “climate damages,” keeping the issue in the headlines and on corporate balance sheets.
3. The “Chevron” and “Major Questions” Shield
While the end of Chevron deference (via Loper Bright) and the Major Questions Doctrine were used to strike down the EF, they also create a “litigation treadmill”:
Death by a Thousand Injunctions: Every attempt by the new administration to deregulate will be met with lawsuits from environmental groups (like the NRDC and Sierra Club). These groups argue that even without the EF, other parts of the Clean Air Act still require action.
Stare Decisis: The Supreme Court has previously upheld the EF in Massachusetts v. EPA. While the current administration has repealed it administratively, the legal “Best Interpretation” of the original statutes remains a point of intense litigation that will take years to resolve.
Summary of the “Alarmism” Persistence
The “alarmism” will continue because the infrastructure of climate action has decentralized. What was once a single federal “on/off switch” (the Endangerment Finding) has been replaced by:

• 50 different state battlegrounds.
• Dozens of active courtroom dramas targeting the private sector.
• International pressure from the EU and COP30 (Brazil) targets that U.S. multinationals must still navigate.

Within a year, the “chaos” of a fragmented regulatory landscape may prove just as pervasive as the federal mandates it replaced.
