El-Sayed, Lawrence and McKinney all won progressive campaigns in Michigan last night by talking about climate and clean energy like it was a kitchen-table issue — because skyrocketing energy bills and endless wildfire smoke matter to people.

Climate pals, what are your favorite examples of actions that simultaneously reduce climate pollution and help us adapt to climate changes that we can no longer avoid? Joint Adaptation and Mitigation (JAM), if you will.

I work at the intersection of the climate and biodiversity crises, so I especially value actions that support adaptation and mitigation AND conservation, e.g.,: Expanding urban tree canopy, green roofs, rain gardens, etc. to mitigate heat and flooding, sequester carbon, and provide habitat.

The conventional wisdom is the Democrats' big climate law failed to deliver votes and then died. That's wrong. My new study finds its factories moved 2.5 million votes—more than Trump's margin. And the law's still alive. My latest in @theatlantic.com. Gift link! www.theatlantic.com/ideas/2026/0...

Bidenomics Was More Successful Than People Think

Conventional wisdom holds that Joe Biden’s bet on climate investment was a bust. The data suggest otherwise.

All the projections I've ever worked with predicted an acceleration in the rate of global warming if we continued to increase our emissions. The fact that so many people are shocked about this honestly surprises me. I guess no one ever reads things like the IPCC or National Climate Assessment 🤷‍♀️

A figure I made for NCA4 about 10 years ago. The world was tracking the RCP8.5 scenario equivalent emissions through about 2020, and that's the temperature change we're seeing today.

“It’s time to make oil giants pay up to repair the climate breakdown they’re driving. Think how many fire and flood defences we could build, or how many solar panels we could install, if big oil paid their fair share in taxes.” @patrickgaley.bsky.social @fossiltreaty.bsky.social

At @csldf.org, we continue to keep hope alive, even after 18 months of relentless and exhausting attacks on science. Part of that hope comes from our growing team - including our new Legal Fellow, Sangita Keshavan, who has hit the ground running: www.csldf.org/2026/08/03/k...

July update: Keeping hope alive - Climate Science Legal Defense Fund

We are pleased to announce that we have added a new Legal Fellow to help with the ever-increasing workload. Sangita…

A reminder: when Zelenskyy offered to share Ukraine’s anti-drone expertise with the US back in March, Trump said he was “the last person we need help from”. Trumps assessment was arrogant and naïve. Ukrainian companies are world leaders in drone production and innovation.

Invisible Rulers is ab how influencers, algorithms, & crowds shape public opinion. The Twitter Files was profoundly impactful BS. Media never reckoned with what it really was: a very effective propaganda campaign led by election deniers to dismantle state capacity. Read more: invisiblerulers.com

The paperback of Invisible Rulers is out today! To celebrate I dropped audio of the Twitter Space where Mike Benz first groomed Matt Taibbi into believing there'd been "mass censorship" of "hundreds of millions of tweets"—something he'd then testify before Congress. open.substack.com/pub/agentsof...

Historian of science Margaret Rossiter (d #OTD in 2025) coined the term #MatildaEffect (1993). Named after suffragist Matilda Joslyn Gage, the Matilda Effect describes a systemic bias where women's scientific achievements are ignored, minimized, or directly attributed to their male colleagues. 1/3

A black-and-white photograph of the pathbreaking American historian of science, Margaret Walsh Rossiter (1944–2025), renowned for coining "the Matilda effect" and documenting the buried history of women in science. Seated in an indoor setting with a soft, blurred background, Rossiter is positioned from the waist up, facing forward with a warm, open smile. She has short, curly gray hair and wears dark, thick-rimmed glasses. She's wearing a light-colored, long-sleeved shirt patterned entirely with small, dark polka dots. She holds a heavy, open book resting on her lap or desk, her left hand steadying the right-hand pages while her right hand rests on the left-hand pages, lightly gripping a pencil. The overall composition is intimate and studious, casting her as an approachable yet deeply focused scholar. The mood is intellectually vibrant and welcoming, reflecting a life dedicated to uncovering the truth.

Not to dunk on this but it isn't really true that the Hormuz oil crisis is driving a solar boom. Here's this chart updated to June of China solar exports, showing that the March spike in exports has subsided and was therefore mostly just export tax rebate effects.

Chart from BloombergNEF and SinoImex showing monthly dollar-value exports of solar cells and modules from China, by market, from November 2024 to June 2026. They spiked to $4.5bn in March 2026 because a key China export tax rebate was removed, fell to $3.1bn in April - still high but possibly due to some spillover effects and deadline missing - and then are back to a normal-ish level of $2.2bn in May and $2.5bn in June.

Absolutely unbelievable how solar power has taken off worldwide during the Hormuz oil crisis. You don't have to hand it to him, but Trump may have done more to finally kick off a global civilization of effete librul solar users than anyone else in the West

Chart showing solar panel exports from China (the main solar panel maker by a long shot) growing steadily & mightily from 2018 through 2026, then spiking by almost 2x in March 2026.

« Hansen’s team found PFOS in Swedish blood samples from 1957 and 1971. After that, her lab analyzed blood that had been collected before 3M created PFOS. It tested negative. Apparently, fluorochemicals had … leached out of 3M’s sprays, coatings and factories — and into all of us.

Decades ago, Kris Hansen showed 3M that its PFAS chemicals were in people's bodies. Her bosses halted her work. Now she wrestles with the secrets that 3M kept from her and the world. (Published May 2024)

The wildfires in the Pacific NW are incredibly sad and devastating. We have to face the fact that a warming climate is unsustainable. As you can see, fires in the Pacific NW are getting much larger in recent decades. The largest fires (100K acres+) have increased by 10-15X since the 1980s. 1/

Low flow on the Danube means Romania is about to close its only nuclear power plant (20% of total energy production). Breathless 24/7 coverage of the historical drought and impending energy crises, not one mention of climate change. In fact pundits are angry Romania recently closed a coal plant.
