A little over a year ago, HHS paused research activities at a NIAID facility and placed the director on leave. It just so happens that this particular facility focused on Ebola and other infectious diseases... silencingscience.org/actions/hhs-...

As I told the NYT in this article, Trump sees fossil fuels as manly and renewables as woke.

"If scientific uncertainty was the real reason for disregarding benefits, a good-faith response would be to conduct more research to reduce the uncertainty. Instead, the Trump administration has... attacked the scientific enterprise.” @michaelgerrard.bsky.social www.csldf.org/wp-content/u...

The Trump administration is revoking or weakening many environmental regulations. In doing so it looks only at the costs of the regulations and completely ignores the benefits. It tries to justify this by claiming there is too much uncertainty to quantify the benefits. If that ...

American combat deaths in World War I: 54,000. American soldiers killed by flu in World War I: 45,000. They would have given anything for a flu vaccine.

This is the latest loss by the Trump administration in the lawsuits challenging its attempts to block renewable energy projects. The courts are repeatedly finding them to have acted arbitrarily and capriciously.

Letting the perfect be the enemy of the necessary. I strongly support community solar (and rooftop, and ...), but this kind of purism leaves the fossil fuel incumbents in place counting their money while the climate pollution continues to accumulate in the atmosphere

Trump's Department of Justice sued the state of Hawaii to try to block it from suing the fossil fuel companies over climate change damages. Hawaii sued anyway. The federal court just dismissed DOJ's suit with prejudice. The court: "Plaintiff United States’ theory ...

Americans DO care about #ClimateChange! Don’t listen to the partisans who lie about this. 72% of Democrats & 46% of independents “worry a great deal” about climate. And 68% of Democrats & 47% of Independents expect global heating to threaten their way of life NOW or in the future.

"If a very blue state like New York moves backwards on climate change as well, that’s a negative sign for the country. If you can’t do it here, can you do it anywhere?"-- @michaelgerrard.bsky.social [gift link]

This is insane.

The Trump administration has removed the chapter on climate change from the "Reference manual on scientific evidence", an essential handbook for judges as they weigh evidence in court. The response of the American Meteorological Society has just been published (below). And...[1/2]

Oil prices are soaring, thanks to the war that Trump started. However, today the U.S. Department of Justice sued California to try to block a program that would advance adoption of electric vehicles. EVs are the top way 🧵

The U.S. Supreme Court just agreed to hear an appeal from Suncor and other fossil fuel companies in a lawsuit brought by the City and County of Boulder seeking money damages related to climate change and the companies' alleged deception. The Colorado Supreme Court had ruled that the case could 🧵

A coalition of public health and environmental groups has just filed a lawsuit against EPA in the DC Circuit court challenging revocation of the greenhouse gas endangerment finding. They are represented by some of the country's leading environmental litigators. aboutblaw.com/bkXr

Trump's EPA said a major justification for revoking the GHG endangerment finding is that emissions from the U.S. transport sector (cars, trucks, etc.) are so low that reducing them wouldn't make any difference to the climate. But if this sector was a country, 🧵

South Fork Wind had a capacity factor of 52% last month - on par w/ NY state's most efficient gas plants And Vineyard Wind had a 75% capacity factor during Winter Storm Fern The data doesn't lie. #OffshoreWind works - especially during cold winter months www.canarymedia.com/articles/off...

EPA isn't now denying that climate change is happening. Instead they are saying that whatever the U.S. does now will not make enough of a difference to warrant the expense to Americans. The U.S. is historically the largest emitter of greenhouse gases, and is abdicating its responsibility.

The press is reporting that EPA is about to withdraw the endangerment finding, the legal basis for EPA regulation of greenhouse gases under the Clean Air Act. As I wrote in September, bit.ly/401lLUw, this would raise a tangle of legal issues. Among them: 🧵

From late last night: The EPA plans this week to repeal a policy that provides the legal foundation for a raft of rules regulating greenhouse gas emissions, marking Trump’s most consequential retreat from the fight against climate change. Gift link @bloomberg.com: www.bloomberg.com/news/article...

"Renewable energy is central to the fight against climate change, and this suit alleges that the companies have stood squarely in the way. Michigan has opened up a whole new battleground in the climate fight" said climate law expert @michaelgerrard.bsky.social www.sierraclub.org/sierra/michi...

A federal court just invalidated the Texas law that prohibits state entities from investing in or contracting with companies that boycott fossil fuels. The court found that the law violates the First Amendment by being both overbroad and unconstitutionally vague, and "permits the State to penalize

🚇💳NYC’s iconic #MetroCard has officially been retired after 30+ years, making way for contactless tap-to-pay OMNY. It began as a tech leap over subway tokens and ended as a beloved piece of NYC transit history. Michael Gerrard shares his reflections: blogs.law.columbia.edu/climatechang...

NEWS: Judge Royce Lamberth ruled against the Trump admin, allowing Orsted to continue construction on its Revolution Wind offshore wind farm. He said Orsted is "likely" to succeed on claims the admin's stop work order targeting offshore wind violates the Administrative Procedures Act.

Trump pulled US out of Paris Climate Agreement in 2017 & again (after Biden rejoined) in 2025. Now he withdraws US from UN Framework Convention on Climate Change, as Project 2025 wanted. In 1992 the Senate unanimously ratified & President GHW Bush signed it. Re-ratifying requires a 2/3 Senate vote.

"Ecuador is the only country in the world whose constitution recognizes nature’s rights to exist, regenerate and be restored, though hundreds of court rulings, local laws, nonbinding declarations and other initiatives worldwide recognize nature’s rights in some form. " 🐸

The retirement of the MetroCard at midnight tonight is bittersweet for me. In 1983, as a young lawyer, I took a year's leave of absence from my law firm to serve as special counsel to Richard Ravitch, chairman of the NY MTA. He gave me the task of leading a study ...

Thanks, Nate. I'm glad that you found my paper to be useful. It's still in draft, so any comments are welcome.

December issue of Sabin Center for Climate Change Law's litigation newsletter: bit.ly/4iK4eJ4. 11 new court decisions from the U.S.; 18 new lawsuits and filings in the U.S.; numerous cases in Brazil and Australia; and cases in Mexico, New Zealand, Portugal, UK, European Court of Human Rights.

EVs beat petrol cars on lifetime emissions — even on “dirty” grids. Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km. We can’t wait for perfect grids: electrify transport and clean the grid now.
