Today is the one-year anniversary of my return to @ucs.org. Reflecting on all we’ve lost and all we’ve done this past year, I’m resolved in our efforts to keep going. We must imagine, and work towards, a brighter future. Don’t let up. blog.ucs.org/gretchen-gol...

Today we won. A U.S. District Court ruled that the administration violated federal law when it secretly convened a group of climate contrarians to produce a thoroughly debunked report to overturn the Endangerment Finding. The science still matters. We won't stop. www.nytimes.com/2026/01/30/c...

Why is the Dept of Transportation trying to torpedo NYC congestion pricing? Why - in God’s name - is Transportation Secretary Sean Duffy on TV smearing the Minnesotans killed by ICE? For @newrepublic.com, I show Trump has turned USDOT into an authoritarian weapon. newrepublic.com/article/2051...

This month, the US EPA made a radical departure from scientific precedent, ignoring the lives saved by air pollution protections and thus granting a long coveted giveaway to polluters. More from my @ucs.org colleagues and I out in @bmj.com today: www.bmj.com/content/392/...

My OpEd with @agu.org @eos.org on #SaveNCAR. Please check out what we can do together to speak on the value of this critical infrastructure, and what I believe is a source of American pride possible by over six decades of public investments. Let’s continue to invest in this important public good.

1/ "The Trump administration must immediately cease all violent, unlawful ICE and Border Patrol actions. We call on Congress to speak up and hold this administration accountable, including calling for a transparent, credible, and just investigation of the violence and deaths in MN and elsewhere."

“The speed, the scope and the severity of the attacks on science are beyond anything we’ve ever seen,” says @gretchentg.bsky.social. My @nature.com story on the human toll of the 2nd Trump presidency. Thx to @dochfroehlich.bsky.social, @briannosek.bsky.social, @katharinehayhoe.com & others.

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...

For those who work on equity issues in transportation, this was a disruptive year, but researchers and advocates aren't going anywhere. Tomorrow theyll prove it. My new @usa.streetsblog.org piece reflecting on #TRBAM week and the present political moment. usa.streetsblog.org/2026/01/14/o...

The fact that air pollution protections save lives (and thus dollars) has long been an inconvenient fact for those who want polluting industries unfettered. This move is indefensible and dangerous. www.nytimes.com/2026/01/12/c...

The authoritarian, violent, and anti-science actions of the Trump admin over the past week show clear contempt for democracy and the public good, endangering people in the US and around the world. Congress must uphold its constitutional responsibility and hold the administration accountable.

"It’s insulting for President Trump and the administration to make claims about public safety when their policies and actions have put so many people, in the United States and around the world, in danger." @gretchentg.bsky.social www.ucs.org/about/news/t...

Parents everywhere want to do everything possible to protect their kids and help them thrive. Secretary Kennedy just robbed us of one of the easiest ways to keep our kids safe, through routine science-based vaccine schedules. I'm angry about the kids that will suffer because of this cruel decision.

Seeing the "last day at [federal agency]" posts today from amazingly talented people who took the Administration's 2025 buy-out is devastating. Regardless of what the White House thinks, know that your expertise and your skills are so valuable and desperately needed in this country, my friends.

We’re closing out a year filled with unprecedented attacks on science, but the pushback is growing. Hear from UCS President @gretchentg.bsky.social on how UCS and the scientific community are standing up for science:

A year ago, I was advancing climate change research and policy at US DOT. Now, I lead @ucs.org and work to carry forward that vision, defend the progress we've made, and build a brighter future for all. May 2026 bring us all progress towards a safer, healthier, and more just world. Happy new year.

It is hard to overstate how wildly inappropriate it is to replace a National Climate Assessment--A process normally involving hundreds scientists, significant public and expert input, and US government-wide coordination--with five climate skeptics using AI. www.eenews.net/articles/its...

I'm concluding a great week at #AGU25! Great to catch up with colleagues past and present and I am energized by the way the geosciences community is showing up in this moment when our work is under threat. Even with near term setbacks, I'm confident our future is bright.

🚨 Late breaking update! 🚨 We'll be joined by @neguse.house.gov, who will be giving brief remarks on news of threats to NCAR during this #AGU25 session at 5:30 CT in E-2. Join us!

The Trump admin intends to dismantle the National Science Foundation National Center for Atmospheric Research (NCAR), one of the US' leading weather and climate research institutions. We must urge Congress to halt this dangerous action immediately. 🔗Take action: act.ucsusa.org/4oWtCwz

At #AGU25 and concerned about news of NCAR dismantling? Join us today 4pm CT. We'll cover independent science action and discuss the key science functions we need the government for--like the critical functions that NCAR provides on weather and climate research. agu.confex.com/agu/agu25/me...

Devastating and dangerous blow to the weather and climate community tonight, as 20,000 earth and space scientists meet at #AGU25. New @ucs.org statement from @carlonimbus.bsky.social on the Trump administration plans to dismantle @ncar-ucar.bsky.social: www.ucs.org/about/news/t...

Thank you for your leadership, @amstatnews.bsky.social.

Join me and @ucs.org at the @agu.org Annual Meeting next week. I'll be presenting Wednesday along with @carlonimbus.bsky.social and others. You can see our scientific sessions listed here and visit us at booth # 684. See you then! #AGU25 www.ucs.org/science-netw...

Job alert: At @ucs.org, we're hiring a science policy director. This could be your dream job! Join us. apply.workable.com/union-of-con...

"How did assaults on science become the norm — and what can we do? An insightful book explores attacks on science from a historical and a personal perspective." | Great review of #ScienceUnderSiege by @gretchentg.bsky.social for @nature.com: www.nature.com/articles/d41...

In times like these, when our government is trying to suppress dissenting voices, I'm grateful to lead an organization that is independently funded by @ucs.org members, not beholden to government or corporate dollars. Help us preserve that independence this #GivingTuesday. ucs.org/give-science

Strong employee experience practices boost satisfaction, prevent burnout and build a motivated, equity-centered workforce. Join @green2-0.bsky.social and leaders including UCS’s president @gretchentg.bsky.social to discuss strengthening our sector. Register: us02web.zoom.us/webinar/regi...

This is a great case of civil society stepping up to fulfill what should be government services in the absence of Federal leadership. If you would have taken the Fed Employee Viewpoint Survey nixed by Trump, take the Partnership for Public Service’s new survey: www.fedmanager.com/news/federal...

This thread and article is really quite something. "Notably absent were any academic researchers or clinicians." 👀

Political appointees should not be dictating the scientific conclusions of federal science agencies. This is wildly inappropriate of Secretary Kennedy and devastatingly dangerous for public trust in the CDC as a scientific authority. www.nytimes.com/2025/11/21/u...

Today: Join me, @lewan.bsky.social, and @ucs.org colleagues to discuss how the scientific community can push back against the growing authoritarian threat and stand up for our democracy. secure.ucs.org/a/2025-11-20...

The Trump Administration has abdicated its responsibility to ensure the public can make science-based health decisions. If the government can't do this job, we must find other ways to bring science to the people.

On scientific topics, especially in public health, federal government webpages have been a trusted way for the public to find reliable information. A CDC webpage with disinformation is dangerous in the short term and erodes public trust in science in the long term. www.cdc.gov/vaccine-safe...

A nice obituary for Alice, who was going to be recognized as one of The Post 50. I hate that we now have to live without this phenomenal woman. #GiftLink wapo.st/49WOdx1

Join me and @green2-0.bsky.social for this virtual event on Building a Resilient Environmental Movement through Best Practices on Wednesday, December 9, 1 - 2 pm ET. Register here: us02web.zoom.us/webinar/regi...

ASK A SCIENTIST: How are UCS and the scientific community fighting back against the Trump administration’s attacks on science? UCS President @gretchentg.bsky.social shares her insights:

US science is under assault like never before, but in response the scientific community can build an alliance for independent science--that can fill gaps left by the decimation of Federal science and reimagine the role of science in policy and society. 🧵 blog.ucs.org/genna-reed/u...

Personal news: We got a heat pump! This seizes on the last days of the clean energy tax credits and eliminates our direct household fossil fuel burning. The big ugly bill will have huge costs for the US energy system, but I'm grateful for US progress and momentum so far. blog.ucs.org/julie-mcnama...

Some personal and political thoughts from me as #COP30 gets underway. We've come too far to give up now. Our kids' future is worth fighting for. blog.ucs.org/gretchen-gol...

Today!

Join me to discuss combatting the New Climate Denialism at @carnegieendowment.org this Wednesday, Oct 1 in DC or online, along with my co-panelists @jeremywallace.bsky.social, @cathfraser.bsky.social, @leonardom-d.bsky.social, @noahjgordon.bsky.social and more. carnegieendowment.org/events/2025/...

Great to see more preservation and public access for critical Federal climate resources as the Administration guts Federal science.

Jumping into #ClimateWeekNYC

Join me this Thursday for a virtual panel on the state of play on US scientific research, along with Obama Administration Science Advisor John Holdren and @thebulletin.org President and CEO Alex Bell.

@ucs.org is headed to #ClimateWeekNYC! Join us with events all week, starting tomorrow. Here's a sampling of where we'll be. 🧵Join us! www.ucs.org/ucs-nyc-clim...

“I was fired for holding the line on scientific integrity. But that line does not disappear with me.” Important testimony today from former CDC director Dr. Susan Coller Monarez:

This week, a group of experts will step up in a big way to ensure that science goes on, despite Trump administration cuts to Federal science advice. They join several other independent science efforts fighting back. 🧵 blog.ucs.org/gretchen-gol...

Science and scientists are under attack like never before and we need all the tools in the toolbox to fight back. Here's my @nature.com book review of Science Under Siege. Thanks for speaking up for science, @michaelemann.bsky.social and @peterhotezmdphd.bsky.social. www.nature.com/articles/d41...

I'm looking forward to keynoting the 16th Annual National Postdoc Appreciation Week hosted by the National Postdoctoral Association next Monday. Join me! #NPAW act.ucsusa.org/41Hr1hy
