New internal industry documents have been uncovered through Massachusetts' climate accountability lawsuit against ExxonMobil. They add to the body of evidence showing Big Oil's early knowledge of the dangers their products posed to the global climate and human wellbeing. Via @insideclimatenews.org.

New Documents Add to Evidence in Climate Deception Case Against ExxonMobil - Inside Climate News

Court filings by the Massachusetts attorney general’s office include previously undisclosed documents, revealing new details about internal deliberations at the oil giant.

The year: 1988. The company: Exxon. Their fear: “a worldwide consensus that action is needed” to mitigate the effects of greenhouse gases – with "substantial negative impacts" on business. Exxon responds by revving up a disinfo campaign like never before. New internal docs offer new insight 🧵

🚨 HAPPENING NOW AT THE SUPREME COURT 🚨 UCS President & CEO @gretchentg.bsky.social and former Washington Governor @govjayinslee.bsky.social are joining forces with survivors of devastating wildfires from Colorado and California.

Today, the U.S. Supreme Court is hearing Suncor v. Boulder — a case that could decide whether communities can put Big Oil companies on trial for deceiving the public about the climate harms of fossil fuels. We're in front of the Court to send a message: Stand with communities, not Big Oil.

A report by US Senate leaders details "transactional corruption" between the fossil fuel industry and the Trump administration. Dismantling pollution protections. Installing oil execs at the EPA. Over $190 BILLION in industry subsidies over the next decade. And that's just the tip of the iceberg🧵⬇️

Thank you to the Members of Congress who were prepared to oppose this bill and to the communities across the country who continue to stand up and fight back against Big Oil’s desperate push to escape accountability. Join the fight at NoImmunityforBigOil.org

🚨 VICTORY! The Big Oil immunity bill has stalled (for now) after the House Judiciary Committee adjourned before bringing the bill for a vote. This fight is far from over, but today is a victory for those who agree that no industry should be above the law.

🚨 BREAKING: This Wednesday (9/16), the House Judiciary Committee will hold a markup on legislation that aims to give Big Oil companies sweeping immunity from any laws or lawsuits seeking to hold them accountable for their role in the climate crisis.

@kathymulvey.bsky.social, accountability campaign director @ucs.org: “Petitioning to have this case heard by the U.S. Supreme Court represents a last-ditch effort to block evidence of the fossil fuel industry’s decades of deceit from being heard in courtrooms across the country."

Fossil fuel interests are working to control how judges see the climate crisis—and it's not subtle. Their goal? Replace independent expertise with industry voices like President Trump's Energy Secretary Chris Wright, a former fracking executive.

Disturbingly, bank financing for fossil fuel expansion *increased* by 27% in 2025, at a time when we desperately need to reduce our reliance on fossil fuels. Any plausible scenario to meet global climate goals demands dramatic reductions in fossil fuel use, in this decade and beyond.

Big Oil companies are going all-out to avoid taking responsibility for the harm caused to communities and for driving the climate crisis. They are using an age-old strategy: delay, distort, and deny. But we won’t let them off the hook.

Attribution science studies use the Carbon Majors data to link corporate emissions to real-world climate impacts that are harming ppl around the globe. One recent study found that emissions from the 178 Carbon Majors entities made 213 heatwaves reported between 2000-2023 more likely & more intense.

Systematic attribution of heatwaves to the emissions of carbon majors - Nature

Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.
