Improvements in water-use efficiency save energy (thus reducing greenhouse gas emissions) AND save water (thus reducing pressure on scarce water resources).
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.
Here's another good one: High albedo "cool" roofs, first popularized by Art Rosenfeld and Hashem Akbari at LBNL. They also championed planting trees to reduce cooling loads and reduce the urban heat island effect. coolroofs.org

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.

Anti-vaccine wins cost lives, harms, and money. "Among 100 confirmed measles cases and 2,946 identified contacts, the total societal cost of the outbreak was estimated at $5.4 million, equivalent to approximately $53,500 per case and $1,800 per contact. ." www.2minutemedicine.com/new-mexico-m...

This kind of Muskian grotesque, ignorant, aggressive, hubris is why corporations are willing to literally destroy the Earth, ecosystems, and #climate in return for a short-term, fleeting, profit.
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 🤷♀️

“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

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...

Hold Big Oil accountable for their deceptions and for the colossal harms they have caused.

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
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.
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
« 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.
