This winter is a postcard from the future with a dramatically warmer climate. It is in our collective power to determine how warm the future is based on how quickly we can reduce our emissions. The time to act is now.

Opinion: All emissions matter. Every tank of gasoline, cross-country flight and fossil-fueled load of laundry makes the earth a little warmer. So anything you do to reduce your emissions makes the problem a little easier to solve — once we collectively decide we want to solve it.

Letter: This summer, when temperatures sizzle and water is scarce, ask yourself what you can do so that our political leaders (state and federal) promote our future instead of destroying it.

Letter: Why are our state leaders so fixated on nuclear energy — one of the most expensive options out there — when we could lead the nation in clean, reliable and economically sound geothermal?

I just resigned from NASA. It breaks my heart to leave, but I’ve become convinced the best path forward is to do the best science I can, and that can’t be here anymore. I’m still in love with the promise of those four magic letters. Ad astra per aspera, and remember: Earth is the only good planet.

The US government lost more than 10,000 STEM PhDs last year, according to an analysis by Science of newly released OPM data, with 11 departures for every hire. And many OPM calls "voluntary" separations were probably pushed. www.science.org/content/arti...

Trump provokes an historically unprecedented brain drain from the US. The United States has lost more than 10,000 STEM Ph.D.s since Trump took office.

the pace of awful news has outstripped our ability to give it the attention and duration it all deserves

Admitting publicly that you only want this bill that is designed to disenfranchise voters is necessary to make sure your party wins is quite a choice. The GOP has done away with subtlety and euphemisms and is now all "we need to cheat because the polls say people don't like us."

The lawyers are likely correct that Carr would lose this in court. They were also likely correct that Trump would lose his lawsuits against ABC and CBS -- but their corporate owners (with much deeper pockets to fight than a local station) folded instead. That’s the real threat.

Let's be clear: you would not be pulling THAADs from South Korea and moving a Marine Expeditionary Unit from Japan to the Gulf two weeks after launching a war on Iran if you had properly anticipated the fallout it would be likely to cause.

when a presidential admin screws up as badly as the trump admin has screwed up in Iran, accountability is essential. There must be congressional hearings, investigations, and consequences for those responsible--including people losing their jobs, going all the way up to the top 1/2

i would like to have people take war seriously

"wherever renewables have been installed, they are turning out to be security gold." prospect.org/2026/03/13/i...

The Iran war is showing that renewable energy is a national security imperative, and that fighting renewables tooth and nail as the White House has been doing since day one deeply undermines national security, as @ryanlcooper.com writes. prospect.org/2026/03/13/i...

credit where due, Macron is right on this one prospect.org/2026/03/13/i...

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath Some costs aren’t costs.

This action "is a ringing alarm bell warning all of us of the extent to which this administration has succeeded in degrading our governing institutions in such a short period of time." My statement progressivereform.org/cpr-blog/epa...

Big 2026 energy news is hotter, deeper, faster! @fervoenergy.bsky.social drilled a successful appraisal well (11 days 555 F) proving a 2nd gigawatt scale greenfield geothermal site in Utah.

Context and quote from me in the this @sltrib.com article. It should be alarming to anyone in Utah that Rocky Mountain Power/PacifiCorp isn't planning to build any new solar, wind, or battery storage in the next 20 years for Utah. #utpol

Excellent new video by Simon Clark interviewing @hausfath.bsky.social discussing the rate of warming and climate sensitivity in great detail. Must watch!

It's hard to keep up, but did we already know Bjorn Lomborg was hanging out with Epstein?

Recommended read: A commentary co-authored by climate scientist Prof @clequere.bsky.social in Nature argued that several climate trends have locked in “irreversible progress in climate action”.

So many reports of ways that climate change is costing us lots of money now and near term. No longer far off in the future. This one might connect with people interested in outdoor sports. Each might not seem big, but added up climate change is already costing us far more than clean energy.

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up. Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes. More: www.climatecentral.org/climate-serv...

Whether you like it or not, climate policy is energy policy. The misguided decision to leave these international organizations means that US interests will not be represented in rooms where international energy decisions are being made. It's undermining US national interests.

How about some good news? In December 2025 wind surpassed coal in PacifiCorp's (Rocky Mountain Power's parent) monthly generation. Thanks to new transmission lines & a 600 MW Wyoming wind facility coming online last year, we’re building momentum for a #CleanEnergy future. #utpol 🔌💡

Joint European statement on Greenland. They moved quickly after Miller’s comments about annexation last night.

No gas, no problem in Norway. Most buyers went electric last year, even as incentives start to fade. insideevs.com/news/783304/...

Don't support the US illegally stealing Venezuela's oil? Get yourself an EV and destroy that demand!

Worth noting, there will never be an illegal war over solar energy. That's what true energy independence looks like.

The big difference between 2002 and 2026 is that we now have viable alternatives to oil for transport. Don't want to support an illegal foreign war for oil? Drive an EV!

Instead of whatever this is, we should have a government getting lots of new homes and apartments built, lots of clean energy built, lots of high speed rail and transit and bike lanes built, human rights for everyone, economic & healthcare opportunities for all, & innovation that leads the world.

One thing I wrote about here is how technology has made buses *way* more convenient while techno-futurists were obsessed with flying taxis and self-driving cars.

NYU law professor Ryan Goodman and his nonpartisan team compiled a review that found more than 35 federal judges had explicitly stated that the Trump’s Justice Department lawyers were providing false, highly misleading, or intentionally inaccurate information in cases.

Lauren said it best: we're getting coal for Christmas. This is just so incredibly stupid. There's not even coal supply or demand. www.seattletimes.com/seattle-news...

Unfortunately, hiding your head in the sand will not make climate change go away www.nytimes.com/2025/12/09/c...

Something to be thankful for! Utah's largest coal-fired power plant—the Intermountain Power Project, located in the west desert near Delta and serving southern California—stopped burning coal at mid-day on Wednesday, just in time for Thanksgiving. 🔌💡

First electric cars and buses, now trucks: in the past we were often told that electric trucks would not be feasible. But the market is picking up speed and electric trucks have become a reality. Expectations are for significant market expansion in the coming years.

Gas car sales have fallen 30% from their peak in 2017 as EV's have exploded in popularity around the world Only one direction for cars and that's cheaper, cleaner and better Cold as ICE 😎

It's so over for Tesla in China. The Xiaomi YU7, a Model Y rival, not only outsold Tesla's Model Y in October, but it outsold Tesla's *total* October sales of 26,006 vehicles by 29%. 💀☠️
