I don't say this often but: I'm so proud to be a climate and environment reporter. We cover an issue that is vitally important to humanity and the natural world. 14 of my climate colleagues at the Post were laid off today and I'm devastated. www.climatecoloredgoggles.com/p/washington...

ICYMI: New York’s Sunrise Wind has won its court case and can get back to work. It was the last project held up by Trump’s offshore wind ban.

BREAKING: Five-year-old Liam Conejo Ramos and his dad have returned to Minnesota after being released by ICE, Texas lawmaker says.

“That report was kept secret until it was unveiled as part of Trump administration’s proposal to overturn the Endangerment Finding. The proposal relies extensively on the [Climate Working Group’s] report, citing it 22 times.”

A Minnesota woman observing ICE agents in her car was cornered on one-way streets. An agent approached, called her by name—citing facial recognition. Days later, her Global Entry and TSA privileges were revoked, with no explanation.

“Trump officials have delayed finalizing the repeal of a landmark legal opinion key to their effort to eliminating the Environmental Protection Agency’s climate rules because of concerns the proposal is too weak to withstand a court challenge.”

As the world quickly approaches 1.5C, researchers have a call in Nature to rethink the utility of temperature targets – and to potentially replace them with more actionable and precise targets around clean energy:

DeForest, WI, joins the list of towns and villages rejecting data center development. The village won't move forward with plans to annex 1,600 acres from a neighboring town to allow the construction of a data center.

New analysis from @globalenergymon.bsky.social finds that planned U.S. natural gas power capacity additions to meet data center demand with on-site power reached 97 GW in 2025, nearly 40% of all gas capacity in development and a huge jump from 2024. globalenergymonitor.org/report/betti...

"A team of career lawyers and technical experts would usually be involved, but only a few attorneys with the Office of General Counsel are known to be working on the rulemaking, the former officials said. It’s unclear if any agency experts on climate science are involved in the process."

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

That’s now nearly 5 GW of offshore wind capacity that continue construction between Vineyard Wind, Revolution Wind, Empire Wind, and Coastal Virginia Offshore Wind.

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link) www.theatlantic.com/ideas/2026/0...

In the early 1930s the SA was roughing people up, creating chaos in neighborhoods, seeking to terrorize with the occasional killing. By the late 1930s it had been supplanted by the SS, which was much better trained.

Tomorrow’s front page of the Minnesota Star Tribune: Jan. 23, 2026

Under President Trump, the EPA has stopped estimating the dollar value of lives saved in the cost-benefit analyses for new pollution rules.

The most Wisconsin of comparisons: “Republicans’ bill has also drawn the attention of Wisconsin comedian Charlie Berens, who has been outspoken against data center developments in Wisconsin. […] Berens slammed how small the bill was, joking that there are more regulations on cheese curds.”

I recently sat down with Amy Barrilleaux of Clean Wisconsin to talk about EPA’s proposal to stop valuing the health harms of air pollution, what those health harms are, and the enormous success of the Clean Air Act. Listen here:

We're one year in. The speed, scope and severity of what's happening to American science is beyond anything we've seen before. The reliability of the Federal science and technology enterprise and the people within it, has been shattered. www.nature.com/articles/d41...

I have an op-ed in @captimes.com on EPA’s proposal to ignore the health harms of air pollution in agency rulemaking. “By abandoning its longstanding practice of monetizing public health benefits of air pollution reductions, [EPA] is tilting its cost–benefit calculus in favor of polluting industry.”

The Trump administration is proposing to value the cost of air pollution deaths at $0. It’s no wonder that Trump’s EPA would take this step: avoided premature mortality is regularly the largest category of monetized benefits used to justify Clean Air Act regulation.

New preprint up assessing the air quality and health benefits that could have been possible under the Inflation Reduction Act. Huge effort here with Erin Mayfield, Jamil Farbes, @jessedjenkins.com, Ryan Jones, Tracey Holloway, and @jonathanpatz.bsky.social.

NCAR is one of the most important research facilities in the US. NCAR provides key weather and climate data that help predict severe storms, allows for farmers to prepare for long-term weather patterns, and airlines to fly safely. Call congress to #SaveNCAR today. buff.ly/7ka1BQA

“The Trump administration wants to destroy it. Why? Because NCAR attempts to understand the inequitable impacts of human-caused climate change on the poorest and most vulnerable.”

Proud to be part of the Expert Working Group on Climate Change and Health that just put together a report summarizing the evidence of health harms of climate change to date. Report is here: zenodo.org/records/1728... 🛟 #climatesky

The path between here and a just and livable future is not a smooth curve of managed transition any more (if it ever was). It's white water, surprises, confusion, advance, retreat, learning, messing up, grieving, celebrating, experimenting, truth telling, pausing in the beauty.

Another expert review of the science behind the endangerment finding, this time from health professionals. they conclude that CO2 emissions "pose a clear and indisputable danger to human health and well-being." drive.google.com/fil...

The end of soot-laden windows. The arrival of broadband internet. Cheaper and more reliable electricity. Rhode Island’s first electricity co-op. The return of birdsong. Here are the myriad benefits the first US offshore wind farm has brought to Block Island, from @catrineinhorn.bsky.social.

The recent DOE climate science report misrepresents the work of many researchers. Carbon Brief asked those cited to review the parts of the report where their work was used, and we collectively found 100+ misleading or false statements: interactive.carbonbr...

Beyond frustrating and disappointing that CBS got a rare exclusive sitdown interview with Musk and didn’t ask him a single question about his reckless and ignorant cuts to USAID and all the lives that are being lost across the world as a result of it:

These regulations might produce acute costs for producers from plant retrofits and retirements, but they provide diffuse benefits to all of society from improved air quality and lowered greenhouse gas emissions. It’s little surprise which group’s interests matter to EPA administrator Lee Zeldin.

The political theory behind IRA was roughly as follows: We have lost control of the information landscape and can no longer win rhetorical or purely political battles; however, if we make substantive policy progress that directly touches voters' lives, they will notice and reward us.

Researchers at Microsoft just introduced Aurora, their new AI earth system model. It can produce global air quality forecasts that match or beat the performance of the Copernicus Atmosphere Monitoring Service — at 100,000 times the speed.

They blame pollution but cut the EPA and clean air and water regulations. They blame poor nutrition but cut SNAP and programs to bring local produce to schools. They blame increased screen time while destroying public infrastructure that connects people. All while they take millions off healthcare.

Whenever Trump announces some new authoritarian policy, like the ban on Harvard international students, the first two questions should always be: 1) Can he do that? 2) If he can't, will he get away with it? More often that not, the answers are no. And I think this case will fit the pattern.

Breaking News: Harvard University sued the Trump administration less than a day after the government said it would block international students from attending.

"The decision represents the first time since the creation of the [Clean Air Act] that Congress has rolled back its environmental protections." This means some facilities will no longer need to use maximum achievable emission controls for hazardous air pollutants such as mercury, lead, and benzene.

We're getting closer by the day to "Chain-Gang All Stars" by Nana Kwame Adjei-Brenyah.

NEW: The Energy Information Administration has long provided reliable data on everything from oil and gas to alternative energy. Now one of its signature reports has been slashed and a second one canceled entirely amid sweeping job reductions and turmoil. By @peterelkind.bsky.social

Most Americans frequently use federal science information. But few are concerned that cuts to federal science spending could affect their access to such information, a new poll finds.

The scientific community is at a pivotal moment right now. And we are seeing things start to shift. Now is the time for scientists and scientific institutions to step up. No one is coming to save us. 🧵

Because they felt that air pollution isn't killing enough Americans, the Senate voted to overturn an EPA rule that limits toxic air pollutants emitted by industrial facilities, marking the first time Congress has weakened protections under the Clean Air Act.

During graduate school, studies published in Environmental Health Perspectives regularly offered models of robust and compelling science that helped guide my work. Some of the best research on air quality and public health graces EHP's pages. The journal's discontinuation would be a real shame.

AGU has filed a new lawsuit to prevent the Administration’s dismantling of U.S. scientific agencies. We’re proud to take this stand with our plaintiffs’ coalition for our federal workforce. buff.ly/3U56ooz

Well, it's official. We just received notice that all authors on the Sixth National Climate Assessment have just been released from their roles. The NCA is a vital, Congressionally mandated resource for our nation as we prepare for the impacts of climate change. This is a huge loss.
