“The Trump administration revoked a scientific finding that carbon dioxide and other greenhouse gases threaten public health”
Summary
On February 14, 2026, the Environmental Protection Agency under the Trump administration formally withdrew the 2009 Endangerment Finding, which had determined that greenhouse gases including carbon dioxide endanger public health and welfare. This action was directed by Executive Order 14173, signed on January 20, 2025, titled 'Unleashing American Energy,' which instructed the EPA Administrator to review and consider suspending, revising, or rescinding the finding.

Original 2009 EPA finding that greenhouse gases endanger public health and welfare
Evidence Supporting the Claim
- The EPA published a final action on February 14, 2026, formally withdrawing the 2009 Endangerment Finding that determined greenhouse gases threaten public health and welfare
- Executive Order 14173, signed January 20, 2025, specifically directed the EPA Administrator to consider suspending, revising, or rescinding the Endangerment Finding
- The withdrawal action removed the scientific determination that current and projected atmospheric concentrations of greenhouse gases endanger the health and welfare of current and future generations
Evidence Against / Context
- The withdrawal faces immediate legal challenges and may not be upheld by federal courts, as the original finding was based on extensive scientific review
- Multiple states and environmental organizations filed lawsuits challenging the withdrawal on procedural and scientific grounds
Timeline

What This Means
Structured interpretation — not opinion
Key takeaway 1
The withdrawal represents a reversal of the federal government's official position on whether greenhouse gases pose a threat to public health, eliminating the scientific basis for federal regulation of carbon emissions under the Clean Air Act
Key takeaway 2
This action affects the legal foundation for numerous federal climate regulations, including vehicle emissions standards and power plant rules that were predicated on the endangerment determination
Key takeaway 3
The withdrawal may face extended litigation, as courts have previously upheld the scientific basis of the original finding and may require the EPA to provide substantial scientific justification for reversing its position

“Black rain or 'acid rain' fell over parts of Iran after U.S.-Israeli airstrikes on oil depots”
Dark-colored rain fell over parts of Iran following airstrikes on oil infrastructure in March 2026. While atmospheric scientists confirmed the phenomenon was caused by combustion particulates from burning oil facilities mixing with precipitation, the term 'acid rain' is technically inaccurate, as this represents particulate pollution rather than the sulfur dioxide-based acidification process traditionally defined as acid rain.
“Trump administration revoked a scientific finding that carbon dioxide and other greenhouse gases threaten public health”
The Trump administration issued Executive Order 'Strengthening United States National Defense With America's Beautiful Clean Coal Power Generation Fleet' on February 17, 2026, which revoked the EPA's endangerment finding regarding carbon dioxide and other greenhouse gases. This finding, originally established in 2009, concluded that greenhouse gases threaten public health and welfare under the Clean Air Act.
“Seven Western states that depend on the Colorado River missed a second deadline to agree on a plan addressing drought and water shortages”
Seven Western states reliant on the Colorado River failed to reach consensus by a February 2026 deadline to develop a new water management plan. This represents the second missed deadline for states to negotiate conservation measures as the river system faces ongoing drought conditions and declining water levels.
