- King County judge rejected oil companies' motions to dismiss Misti Leon's wrongful death lawsuit over her mother's death during the June 2021 Pacific Northwest heat dome, which scientists said was "virtually impossible" without climate change; an estimated 1,200 people died that week.
- Nearly 40 climate lawsuits are now pending against oil majors nationwide, and at least five (Massachusetts, Vermont, Connecticut, D.C., and Honolulu) have reached the discovery stage — the final major step before trial.
- Boulder, Colorado's lawsuit against Exxon Mobil and Suncor Energy heads to the Supreme Court this fall, with a ruling that could reshape existing climate cases and influence plaintiff legal strategies.
- Utah, Iowa, Tennessee, Oklahoma, and Louisiana have signed laws shielding fossil fuel companies from climate-related suits, while Montana and Utah narrowed "public nuisance" definitions to block damages claims — and Congressional Republicans have introduced federal immunity bills backed by the American Petroleum Institute.
- The Department of Justice filed its own suit against Minnesota's climate case in May, echoing industry talking points about "American energy dominance"; longtime Exxon lawyer Robert Levy joined the DOJ's newly renamed "Energy and Natural Resources Division."
- A new National Academies report concludes that climate-attribution science is increasingly robust for extreme heat, cold, and heavy rainfall — prompting opposition research firm Argus Insight to seek internal communications between panel members and climate litigation researchers before the report's release.
- Trump ordered officials to review the National Academies' conduct, writing on Truth Social that "Our Taxpayers should not be funding Climate Fraud," after Republican AGs pressured the body and the Federal Judicial Center to scrub a climate-science chapter from judges' reference manuals.
Why it matters: The industry's full-spectrum counter-mobilization — state immunity laws, DOJ lawsuits, congressional bills, and attacks on attribution science — signals that plaintiffs' theories are gaining legal traction and that the tobacco-industry litigation template is now a live threat to fossil fuel balance sheets. The Boulder case before the Supreme Court this fall is the single decision most likely to determine whether these suits survive or stall.
