🌍 Today is the International Day for the Total Elimination of Nuclear Weapons. OPSR is proud to endorse this joint appeal, making an urgent global call to abolish nukes, cut dangerous budgets, and invest in a safer, healthier future for all. 👉 tinyurl.com/NuclearAbolitionDay

My book comes out in three weeks. www.bloomsbury.com/us/contempor...

Excellent @sciam.bsky.social Golden Dome article details the lack of information about the proposed system, the enormous amount of taxpayer $$$s it will consume (even as it fails), & the negative ramifications for US security overall: www.scientificamerican.com/article/u-s-...

The president has sole authority to order nuclear use- How did we get here? How does it work? What’s the issue? Can we solve it? My new @scientistsorg.bsky.social report on nuclear launch authority in the U.S. - “All the King’s Weapons” - is out! Read it below 👇 fas.org/publication/...

“A law firm representing opponents of offshore wind farms is demanding that Brown University retract research that details links between the fossil fuel industry and anti-wind groups.” www.nytimes.com/2025/08/25/c...

Inspired by this article, I finally sat down with John Hersey's Hiroshima this Saturday while at the river. In the book Hersey interviews a handful of survivors a year after Hiroshima, with follow ups 40 years later. The stories in that book will likely stay with me the rest of my life.

Was interviewed on Al Jazeera earlier today on the 80th commemoration of #Hiroshima and #nuclear weapons. vimeo.com/1107535248?s...

Visit the Hiroshima Peace Museum exhibit at the Corvallis Museum, now til Aug. 10 (closed Mon and Tues; always free for OSU students w/ID card). There's a commemoration at 6:30pm Aug. 6 at Howland Plaza @ First St. & Madison Ave & an all ages "Family Peace Day", 1-3 pm Aug. 9 at the Corvallis Museum

"ORGANIZATION FOR NATIONAL SECURITY," slide 11 of 41 [gallery]

The Declaration's final recommendation calls on scientists, academics, civil society, and communities of faith to help create the pressure needed to compel action from global leaders. Without action, it warns, “there can be no doubt that our luck will finally run out.”

Very excited to check this out

"And the advancement of that movement—for socialism, for freedom, for social peace, for the unity of the multiethnic working class—is how we end the 9/11 Era." www.forever-wars.com/this-is-the-...

I guess blowing up Fordow and declaring Iran denuclearized is the new closing Yongbyon and declaring North Korea denuclearized?

Aren’t you all glad we have this thing called deterrence? Everyone seems deterred from attacking each other and I feel so much safer with nuclear weapons in the world.

We had a deal in place. It was working. Iran was not building nuclear weapons.

If the act of war is illegal you really and truly do not need a preamble about how you're glad the president who did the illegal thing picked a target you're happy to see hit

ICAN condemns the United States’ illegal military action against Iran’s nuclear facilities. By joining Israel’s strikes, the US is violating international law and putting global non-proliferation efforts at risk.

President Trump’s decision to bomb Iran’s nuclear sites is reckless and draws the US directly into Israel’s war with Iran. This is a war that the American people do not want and the world does not support. We call for Congress to intervene and halt this war.

Have to wonder why any country would ever engage in good faith diplomacy with the United States ever again.

reminding everyone there’s no such thing as a tactical nuclear weapon

Apparently this person was asked to provide medical documents that proved she needed to mask. This is why “health exceptions” to masks bans don’t work.

"Trump reneged on more than a billion dollars the Biden administration promised to tribes for renewable energy and salmon recovery."

We warned the choice was between the Iran nuke deal and war. We were called extremists. Now we have been proven right. Trump killed the Iran deal. He and Bibi are to blame for this strike and the start of this war.

Virtually unrestricted nuclear launch authority. A man you can bait with a Tweet…

Nationalize 'em

lol @carolinehaskins.bsky.social

They're literally doing the meme

www.foreignaffairs.com/united-state... W admin alums arguing that arms races are good, actually You might remember the W admin from its hits like 'no way will missile defense lead to arms races' fast forward 20 years and missile defense is still a money pit but at least we have arms races

Project 2025 isn’t just influential in Washington. Its friends and creators are literally running the show, according to a new analysis from @DeSmog buff.ly/xyzwHZE

*tugs at collar* getting pretty nervous about all these nuclear weapons *wipes brow* better get some more nuclear weapons *loosens tie* in all shapes and sizes

Just going to point out that in just the last month we’ve seen the most intense, multi-modal warfare between two nuclear-armed states ever (India & Pakistan) and now possibly the largest-ever attack on nuclear-capable assets in a nuclear state (UA vs Ru, today). The times they are a-changin’.

A money-pit grift based entirely on extremely bad vibes

My UCS colleague has written a deeply researched and very timely report on the US push to ramp up production of new plutonium "pits," the cores of nuclear weapons. It covers the science, policy, and strategic issues, as well as the impacts of these programs on local communities. Please circulate!

Musk has disappeared from Washington but his influence lives on. Democrats, including the late Rep. Gerry Connolly in one of his last acts, want a probe into Musk's lobbying for defense contracts. My new piece in @newrepublic.com. newrepublic.com/article/1956...

Some movies change hearts and minds. The Day After changed policies. Join us at the Film Forum in NYC anytime during its 10-day run starting May 30 to see Television Event, the documentary about the film that terrified the world into rethinking nuclear weapons. Use promo code THEDAYAFTER.

California renewables are currently producing more than total state power demand. Exporting clean energy to Arizona, Nevada and the Pacific Northwest.

Increasing the variety of nuclear weapons so that there is a specific nuke for any scenario *could* do one thing 1) increase the chances that someone uses one and *would* do another 2) increase the chances that a non-nuke is mistakenly identified as a nuke. Neither of these options is good.

🚨 Multnomah County is considering cutting climate justice and sustainability programs that protect frontline communities, reduce deadly air pollution, and fight fossil fuel giants. These programs work. Gutting them now would be a huge step backward. ✍️ Take action: bit.ly/NoMultCoClimateCuts

NOTHING about this is true.

The comment period for this ends in 3 DAYS. Please leave a comment telling them EVERYONE should be able to get covid boosters. www.regulations.gov/commenton/FD...

It's expensive, it incentives arms racing, it creates the perception first move advantages, it makes accidental launches more likely, it doesn't defend against the most likely means of a nuclear attack, it undercuts arms control, it increases tensions, and as a bonus... it won't work.

I want to emphasize this point. Proponents of the Golden Boondoggle talk vaguely about “protecting America.” But when you look at the science, you need 16,000 satellites to even try to intercept ten missiles. No way this system can work against a determined attack

Missile defense doesn't work, but at least it's stupidly expensive, has no appreciable spillover into other research, and in fact the pursuit of it actively makes nuclear war more likely.

Just finished reading @rayacheson.bsky.social 's "Abolition, Not Arms Control" and it is the rare academic article that has gotten me to say "hell yes" while reading it. They highlight arms control role in "perpetuating the permanence" of nukes and limiting the "horizon of political possibility."

This is a fantastic, accessible guide for journalists looking to shore up their digital security. From @freedom.press freedom.press/digisec/blog...

It will always get under my skin the way that Dr. Garwin's work on the Rumsfeld Commission was immediately used to justify the push for national missile defense, despite his vocal and correct stance against it. His arguments against strategic missile defense are still incredibly valid today.

So we’re accepting when convenient there is a discernible limit to how much wealth one individual really needs.

Great to see NYT use our estimate of Pakistani nuclear warheads, even if they forgot to include credit. www.nytimes.com/2025/05/10/u... Here is where the number comes from, plus more background: fas.org/initiative/s...
