To be in public office right now is to constantly ask yourself: How do I make sure I'm standing on the right side of history? There's a simple answer. The wrong side of history will always tell you to be afraid - the right side of history will always expect you to be brave.

I just really need everybody to understand that everything that’s happening in and to the global economy now (and all the businesses and people in it) is the entirely predictable result of the intentional decisions of one guy who doesn’t understand how the global economy works.

Even when the political winds shift, science must keep moving forward. That’s why @AGU and @ametsoc are stepping up with a first-of-its-kind special collection on climate change in the U.S.—across 29+ peer-reviewed journals. 🌍📚 Read all about it: buff.ly/6G05hQD

NEW: Fossil fuel firms like Chevron and Exxon owe the world trillions of dollars. Today in @nature.com, @jsmankin.bsky.social and I show economic losses from rising heat waves directly traceable to these firms, providing scientific support for climate accountability. www.nature.com/articles/s41...

Some photos of Saturn are simply breathtaking.

Feeling compelled to lift up the inspiring, REAL Women Astronauts in our history. Thank you. 🌏

#ProudBlue Looks like Prohect 2025 is pushing on. The EPA plans to end long-standing rules requiring polluters to report climate-warming emissions. www.propublica.org/article/trum...

A tricky thing about modern society is that no one has any idea when they don’t die. Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

January-March 2025, temperature departure from normal. 😭

Stand by Each Other “The People, United, will never be divided.” #handsoff our #democracy

Hey all. Please call your reps and get these tariffs under the control of Congress again and erased from the books. We need housing. We are looking at 25%+ construction increases with tariffs. No one wins in a trade war.

The entire permanent staff of the Division of Environmental Health Science and Practice was laid off. This division addresses issues such as asthma and air pollution, climate change and health, childhood lead poisoning, and cancer clusters.

Wildfire events are becoming more and more common, but even if your building has been spared by the flames, smoke can still infiltrate your home and bring dangerous toxins with it. Learn how Passive House can help in our latest blog post: hubs.ly/Q03fkNVN0

While no places in the Contiguous U.S. had a record warmest March, nearly everywhere was warmer than normal and a very large area was much warmer than normal.

This matters. I hope a parade of senators do this and start to slow and stop the government in protest. We need hope out here. And the Senator “filibustering” by reading our letters matters. It’s important to watch him impacted by what he is reading, too. Thank you.

A stark reminder that climate scientists have been conservative in their assessments-or thought presenting all the data would propel change. Instead, this US government plans to accelerate destruction-including privatizing and destroying national parkland. 🧵

Please follow @bwca.bsky.social and keep up with advocacy to preserve this beautiful wetland in Northeastern Minnesota. If you are Canadian, also stay informed! The watershed flows across the border and mining impacts would also affect Canada’s environment.

Make sure to follow @freshenergy.bsky.social !

Whenever I show the map of the climatological coldest day or month of the year, people always ask why it's December in most of the West and not January. It didn't used to be this way. The answer is, ... the month of January has warmed much faster than December, so December just hasn't caught up yet.

“There is only one path forward: prevent any further increase in atmospheric energy levels. That means keeping emissions out of the atmosphere. That means burning less carbon or capturing it at the point of combustion. These are the only two levers. Everything else is delay or distraction.” 🧵

Jeffrey Goldberg thinking he was being pranked and then realizing he was actually just in the war plans group chat is such a good microcosm of how it feels to be alive right now, everything seems fake until you realize it’s actually real and incredibly stupid

😔

Voter: "I've never been involved in politics before, but this is getting really scary... this insane President talks about Canada as the 51st state... why is he not being impeached?" Crowd: *wild applause* I'm glad to see American voters standing up for our neighbors to the north.

I want to share with you three rules for fighting tyrannical fear and intimidation, gleaned from discussions I’ve had with a number of people who have lived in repressive regimes. https://robertreich.substack.com/p/how-to-respond-to-fear-and-intimidation

Wow. I do not recognize my country. 😔

Can everyone talk about DOGE exactly the way @erinmayequade.bsky.social of the MN state Senate just did. Thank you.

US citizen supporting the sovereignty of Canada… in all the ways I can. 🇨🇦 So many good, earth friendly and well made products in Canada! Etee, Ten Tree, Kodiak have been favorites for years, and I’ve recently discovered Pela Case and Red Canoe. What’s your favorite?

thebulletin.org/2025/03/fore... Me and my colleagues at Cornell wrote for the @thebulletin.org: “Put bluntly: Americans will die and American businesses will lose untold billions if we do not protect NOAA and NWS.”

From ~ 80F to a blizzard in 12 hours in Madison & western Minnesota. 🌡️❄️ That's Armistice Day Blizzard speed weather whiplash. This storm would kill many in the days before NOAA, weather satellites, Doppler, weather balloons & numerical forecast models. Food for thought given NOAA cuts. #mnwx

A good time to remember that wildfires aren’t only on the west coast, and this is a really bad time to shut down @noaa.gov + @nws.noaa.gov + park rangers, firefighters and climate scientists. #fightclimatechange #democracy 1/2…

Ya’ll this is chilling. The FBI has ordered the freezing of the bank accounts of organizations who were chosen to administer IRA grants to reduce greenhouse gases and fight climate change. Climate change is here and real. We are wasting time we don’t have by criminalizing sustainable work.

Thank you @governorwalz.mn.gov If the Republican in your district is too chicken to listen to you at a Town Hall, looks like Governor Walz will, and lead to motivate action. Perhaps a good time to mention Camp Wellstone and late Sen Paul Wellstone’s legacy 🙌🏼 Let’s lead, Minnesota! #freedom

Paradigm shift needed: Talk about the cost of inaction, instead of telling us change is expensive. The status quo is expensive, inefficient, ineffective. We only build the way we do now because we are used to it. Not because it is the best way to solve today’s needs.

Thrilled to learn about this new product today at a mass timber lecture. Modern, wooden wind turbines! Impressive. #RenewableEnergy modvion.com/the-product/

The mass firing of both new hires and recently promoted senior staff within #NOAA, including mission-critical and life-saving roles at the National Weather Service (#NWS), is profoundly alarming. 1/11

good

Want to make a difference and #fightclimatechange while building better, more comfortable buildings? Learn about #passivehouse building! If in the Twin Cities, join @phmnorg.bsky.social at Bauhaus Brew Labs in NE Mpls 7pm tonight! passivehouseminnesota.org/2025/01/31/p...

In a new era where we are witnessing the firing of some of our greatest minds serving our country, it was a joy to get to experience the Twin Cities Regional Science Fair as one of many judges. What an impressive crew of youth excited about science. #supportscience

LOVE this. ❤️ A huge thank you to the hopefulness of Star Trek Next Generation, for envisioning a world of peace between nations and the Earth as one global force for good in the universe. Hope, morality, dreams…envisioning a better world…motivates so many of us. #fightclimatechange #worldpeace 🌎

US Business Leaders must also step up and protect science and increase their commitment to #fightclimatechange. Build a #passivehouse project, embrace clean energy, continue your climate change mitigation and sustainability work. #freedom #protectscience

Friends of the cultivated discourse, uncompromised efficiency, quality indoor environments protecting you in all climates. I am delighted that #Passivhaus #PassiveHouse #EnerPHit Wolfgang Feist is finally here. Follow please: @wolfgangfeist.bsky.social

After watching JD Vance’s arrogant and ignorant speech in Munich…I am so sad to agree. Canada, EU, all US historic allies need to stand up to this monstrous administration before it silences those of us on the inside and wrecks havoc by flaming your own alt right people. #democracy

Save the date: The 28th Int'l Passive House Conference is in Essen, Germany, on April 24-25, 2026!🎉 Workshops will precede the conference, followed by excursions on April 26. The theme is "Driving Transformation with Energy Efficiency." 📣Stay tuned for the call for papers! passivehouseconference.org

Electrification is the key to our long-term energy independence. Pair with #PassiveHouse building to reduce energy used = independence from fossil fuel volatility and emissions, decrease cost, increase resilience and durability of the building structure, and increase comfort.

Worried about losing access to US federal data that may go off-line, or already is? You’re not alone—but duplication isn’t the answer. Many ongoing efforts have already archived key datasets and many more are ongoing. Check out these existing resources and, if you can, support their work. 🧵

An acre of land can power a car to go 13,000 miles per year using biofuel (corn ethanol), or 900,000 miles per year using solar.

No one elected Elon Musk. As Donald Trump allows Musk to access people’s personal information and shut down government funding, Republicans in Washington will also own the consequences. We must do everything in our power to push back and protect people from harm.
