Overview

• The National Academies concluded the evidence that greenhouse gases harm health and welfare is beyond scientific dispute and that the 2009 endangerment finding is reinforced by stronger research.
• EPA has proposed revoking the finding using economic and scientific arguments, citing a DOE report that outside experts and a federal judge criticized for a secretive, non‑transparent process.
• U.S. District Judge William Young rebuked DOE’s process under federal transparency laws, declining to block consideration of the report but finding it amounted to policy advice rather than a mere literature review.
• More than 1,000 scientists delivered a letter denouncing the rollback and disputing the DOE analysis, while Senate Democrats requested documents from two dozen companies and groups about lobbying on the proposal.
• EPA says many earlier predictions have not materialized and is taking public comments through Sept. 22, with more than 100,000 already submitted as litigation and oversight efforts continue.
