Looks like the statewide initiative that would chop Los Angeles' ULA "mansion tax" is going to qualify for the November ballot per @politico Playbook PM. Backers are turning in 1.2m signatures and need 874k valid ones www.politico.com/newsletters/...

If upheld by the courts, EPA's repeal of the endangerment finding would virtually end federal climate regulation. But what about state climate action? The answer is complicated but mostly positive. legal-planet.org/2026/02/23/w...

I urge you to stop what you're doing and watch Alysa Liu's free skate from yesterday. I have never seen anything like this. I understand why sports writers are born now. I have never seen anyone as free from the burdens of this world as this pierced Oakland girl spinning to Donna Summers.

“What happened to the streetcars that used to be around Oakland and the East Bay?” “It’s really a story of technology change,” says @ethanelkind.bsky.social, climate program director at @cleeberkeley.bsky.social www.kqed.org/news/1207376... via @kqednews.kqed.org @danbrekke.bsky.social #BayCurious

The Oakland Ballers are a great example of grassroots community revitalization, and the quality of baseball play is surprisingly good. Great write up here on the team’s future vision.

California needs to step up on clean trucks to counter federal rollbacks | #Opinion by @ethanelkind.bsky.social & Marie Grimm @cleeberkeley.bsky.social via @sacbee.com

🧵 THREAD: Energy Empire — The Podcast Clean Energy Needs 1/ For most of my career, people asked why I stuck with solar when it was fringe. My uncle said it was a career mistake. Turns out it wasn’t.

How can California counter federal rollbacks and maintain momentum on clean trucks? My op-ed w/ Marie Grimm in today's @sacbee.com has some recommendiations, based on our recent @cleeberkeley.bsky.social & @uclalawemmett.bsky.social report: www.sacbee.com/opinion/arti...

Ethiopia banned ICE vehicle imports 2 years ago & now 6% of all vehicles there are EVs, up from 1%. They have cheap hydroelectricity for fuel and are reducing oil imports. Plus they're assembling many EVs in country now due to incentives, boosting local jobs: financialpost.com/pmn/business...

"...China’s developmental drive toward green growth is ultimately a positive force for the planet. Decarbonization is more likely to succeed when tied to economic self-interest than when driven solely by moral obligation or foreign pressure."

"Heat pumps outsold fossil gas–fired furnaces in the U.S. yet again last year. That’s the fourth year in a row," reports @alisontakemura.bsky.social: www.canarymedia.com/articles/hea... 🔌💡

Hotel guests are fleeing early because of the snowstorm. Traffic to the Bay Area and Reno is jammed due to gridlock, plows and crashes. Drivers are clearing snow off windshields and having to buy tire chains. But not us. Our Amtrak is on time. We'll relax in the dining car. The smart way to go.

LA City Council: serving hyper local special interests over the greater good since 1850

Sorry, but this @nytimes.com op-ed on free fares in New York City, by @galvinalmanza.bsky.social, is deeply ignorant of the issues. It proposes that pretty social justice vibes and some careless citations will change facts of math. Thread: 1/ www.nytimes.com/2026/02/13/o...

“California is struggling with wildfire costs ... which are linked strongly to a warming climate. I think that opens up a lot of legal avenues for states like California,” @ethanelkind.bsky.social, director of the @cleeberkeley.bsky.social Climate Program to @calmatters.org: https://bit.ly/4rIYUZI

As I told @gauchoesque.bsky.social for this piece, the rollback of the federal endangerment finding could ironically allow states like California to pursue more aggressive regulation and litigation against polluters.

Like two ships passing in the night... www.eenews.net/articles/chi...

Final EIA-860 is out, and 2025 really did it: 54 GW of new U.S. electric capacity, 96% clean. Solar again carries the offense, and we built more storage in 2025 than the cumulative total through 2023. More and more and more additions... but also record low retirements.

Good example here of how renewable energy companies are now ramping up investments outside the US, as offshore wind developer Orsted pitches a big project off of Australia's coast: renewablesnow.com/news/rsted-f...

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

You can look up the wildfire risk for any address in the US with @carbonplan.org new Open Climate Risk map: carbonplan.org/research/cli...

Revoking the endangerment finding would mean full-blown warfare against all things climate. Some thoughts from our Ann Carlson who has been tracking this all year🧵

Wild fact from @billmckibben.bsky.social's latest newsletter: "The last colder-than-average month on planet earth was in February of 1985, which means that no one under the age of forty has ever known one."

This BART station area has been long overdue for investment.

It's the dead of winter, and California just supplied a peak of 117% of its demand with solar alone and 136% of its demand from WindWaterSolar and over 100% of demand for 6 hours. Gas output down 58% and batteries output up 303% in 2025 v '2023 Solar+batteries replacing gas

Ethan Elkind, climate program director at @cleeberkeley.bsky.social, told @calmatters.org structuring the incentives as grants allows the state to set the terms automakers must meet to access the money, giving California leverage over manufacturers: https://bit.ly/3O1iNgb @ethanelkind.bsky.social

The rest of the world is moving forward aggressively on transportation electrification, taking advantage of low-cost batteries & inexpensive EVs. Kenya is a great example: abcnews.go.com/Internationa...

$34B in clean energy projects cancelled last year. Most of the communities (and voters) that would have benefitted probably didn't even know they were happening. Just a huge setback for the US power grid, affordability, and global competitiveness. www.eenews.net/articles/us-...

$1B for an 8-mile bikeway along the LA River would probably make this the most expensive bike lane in history. Here Joe Linton describes how LA Metro could actually build the (admittedly complicated) project with the money it actually has, namely by shrinking the width from 20' to 10-12 feet.
