It got overshadowed by the pipeline news, but NYS’s deal to allow Greenidge Generation to keep operating an upstate gas plant *for the sole purpose of mining bitcoin* might be almost as big of a reversal gothamist.com/news/upstate...
Upstate NY Bitcoin mine agrees to slash emissions, will get air permit from the state
The move comes days after Hochul’s administration paved the way for a new natural gas pipeline in New York Harbor.

A bit of happy news! After years of work from many people, and in response to a petition from my organization Delaware Riverkeeper Network, EPA finalized revised water quality standards for the tidal Delaware to support all life stages of aquatic life, including Atlantic Sturgeon! 🐟

One of the arguments I often see conservatives make is that public transit should be privatized.
That might work, but only if roads, highways, and parking were privatized as well!
In Japan many transit companies are private but so are expressways and so is parking.

I’ve been thinking about this pivot a lot. What should be the response to those who say climate disruption doesn’t need to be avoided?
A philosophical problem I want to express (which I know may not sit well with many of my colleagues. But fuck it, what's tenure for, eh?)
There's a growing tendency in climate social sciences to conflate "climate minimization" with "climate denial". I think that's a mistake.

The White House is clearly scared of the power states have to build the clean energy economy and is resorting to blatantly unconstitutional tactics. The Trump administration is hoping that pro-climate state governments back down in fear. How should states respond? Simple. Ramp up instead. 🧵
This new White House executive order says that the US Attorney General is going to prevent states from implementing democratically passed laws regarding climate change and clean energy. It scarcely needs stating at this point that this is wildly, unambiguously unconstitutional. Dictator shit.

Great opinion piece by Pamela Darville of @powerinterfaith.bsky.social about Philadelphia's gas distribution system and how the Pennsylvania #GreenAmendment plays a role in the management of municipally-owned gas utilities.
Philadelphia’s decaying gas lines are a ticking time bomb beneath our streets | Opinion
These disasters are not accidents. They are symptoms of PGW’s failure to prioritize safety over profit, leaving communities hostage to pipelines older than most grandparents.

Since Trump's inauguration, his EPA had announced no major step to address water or air pollution.
That changed today. Trump's EPA BOASTED it plans the biggest rollback of safeguards for health, land, water & air quality in US history. To INCREASE harmful pollution to water, air, to your community.

Today's #SCOTUS decision begs the question (posed by the dissent)--how will #EPA issue permits that ensure water quality standards are met? Ends-based limitations at least nominally met that requirement.

If you’re wondering, like I was, what’s “illegal” about DEI efforts in the eyes of the new administration, this thread is a helpful explainer.
For those who haven't seen it, here is DOE's "Dear Colleague" letter on SFFA: www.ed.gov/media/docume.... Most concerningly, the letter states that Ed views actions taken to "increase racial diversity" as unlawful race discrimination, even when they don't treat individuals differently based on race.

![It’s not that the pollution won’t damage communities in south Texas, it’s that the pollution no longer legally matters, the companies argued.
“Following the January 21 [executive order], it is now clear that all of the claimed errors cited by the panel here as the basis for vacatur are based on authorities that are now without force,” Rio Grande LNG wrote. “As a result, they cannot be a proper basis for vacating FERC’s authorization of the Rio Grande project and requiring a supplemental [environmental impact statement] based on purported deficiencies in an environmental justice analysis.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:7r5xfysukluplxs2hufswhe4/bafkreiezinkr44mhva262fguhxitigw7hixphp35wm5z27q6qewth2joku@jpeg)
