Oh the symbolism! COP caught on fire in the heat. No one injured, thankfully. (Not my photo, I wasn’t in the Blue Zone at the time — guess I picked a good time to see a bit of Belém!)

I’m learning a ton at COP30, but my most systematic research is on the ice cream at Sorveteria Cairu — famous for their local tropical fruit flavors. Preliminary results: cupuaçu and chocolate is a better combo than açaí and chocolate, though both were delish. #ResearchPriorities

Many things are giving me joy tonight, not least that JD Vance’s half brother lost 78 to 22! To a half-Indian, half-Tibetan-refugee named Aftab Karma Singh Pureval!!

Hey climate folks (or anyone who has thought about these things) — with the value of offsets largely debunked, what do you do to ameliorate your impact when you have to fly? How best to self-tax for emissions?

It’s a beautiful day to resist democratic backsliding!

Why I’m worried this ceasefire won’t last

Naked bike ride in cold rainy October is what we political scientists call a “costly signal” of resistance (the normal, if you can call it that! one is in the summer) And what we Portlanders call “keepin it weird, keepin it real, keepin it real weird”

Are you affiliated with UPenn (faculty, staff, student, alumni, or parent/guardian of a student)? If so, please consider signing the petition calling on President Jameson to categorically reject the Compact for "Excellence in Higher Education." actionnetwork.org/petitions/ju...

Go Portland! Using its notoriously pain in the ass permitting regime for good!

Smart and beautifully written by a friend and colleague I’m proud to have.

This is next level “this meeting could have been an email”

It was just block after block of people coming from Malcolm X Park headed downtown. Lots of energy despite the heat, and cheers from passersby, as well as church bells ringing in support.

The President of the United States is threatening to go to war with an American city. This is not a joke. This is not normal. Donald Trump isn't a strongman, he's a scared man. Illinois won’t be intimidated by a wannabe dictator.

This is the TIO, they don’t exaggerate. Organizers say nearly 500,000 at Tel Aviv rally, 1 million participated in day’s protests nationwide www.timesofisrael.com/liveblog_ent...

At just over 2 troops per 1000 inhabitants, the deployment to DC is larger per capita than the US deployment in Afghanistan except during the Obama surge 2009-13.

Stop the war, stop the famine, bring the hostages home.

Trump and Netanyahu — united in their goal to starve children.

Holy hell. Nothing surprising but totally shocking.

In case anyone thought agreements like the ones Columbia and Brown have reached were actually going to protect federal funding…

This drives me crazy as a stance towards Israel these days is really quite unrelated to attitudes towards Jews. We have anti-semites who are big fans and there are plenty of Jews and allies who are critics. A stance towards a government and its policies is just that.

If there’s a boycott, I hope it’s strategic. The BoT and uni admin won’t know/care if you don’t give a talk, co-author, or write a tenure letter. They clearly care only about the financial health of the uni not its reputation. Boycott donations or tuition. And/or support StandTogetherForHigherEd

Or as my colleague Suresh Naidu more eloquently put it:

Knew it was coming but still disappointed in my employer today. I have very little confidence that this will satisfy the staunchest defenders of Israel on campus or prevent the Trump from coming after us for more. Has the university admin never heard of a credible commitment problem, FFS?

This is not an accident. This is by design. You think it won’t happen to you. You think you won’t end up there. That is not an accident. That is by design. via @resistofficial.bsky.social

Hundreds of Israelis holding photos of Palestinian children murdered by Israeli airstrikes in Gaza. Palestinian peace activists in Gaza holding photos of Israeli children murdered by Hamas on October 7th. Amid unbearable grief, they carry each other’s pain.

if AI is good. why is everybody trying to trick me into using it

It's official: scientists have linked last week’s European heat wave to fossil-fueled climate change, estimating climate change was responsible for 1,500+ deaths. Those responsible have names & job titles. Find out more here: #heat #extremeweather #makepolluterspay #climate

Air pollution also down (and not diverted to upper Manhattan & the Bronx as feared — actually a smaller dip there too). Win win win

There are many reasons I increasingly dislike fireworks. Trauma to pets, spike in air pollution on the night of 7/4, and the most sobering one in this poem. I know they are pretty, and if your town is setting them off, there is nothing wrong with enjoying them, but please don’t buy them.

Yo, Rep. Gill, try running for office in NYC and eating pizza with a knife and fork. We’ll show you “civilized”

The Al-Baqa cafe was a well-known spot for journalists, among others. That the Israeli government has not allowed foreign reporters in to cover the war in Gaza is by itself a red flag for war crimes. If you don’t want the world to see what you’re doing, what you are doing probably isn’t good.

This is incredibly courageous. www.nytimes.com/2025/06/30/o...

Keep calling your Senators. This isn't over yet if we don't let it be. Here is a super easy tool to do it, takes 5 minutes max. Leave it all in the field to save the future. citizensclimatelobby.org/get-loud-tak...

“Forget about intelligence” is a pretty good mantra for this administration

We had a deal on nukes, not perfect, but good. Trump tore it up, making the US an unreliable negotiator. Unsurprisingly, he failed to get a better one. Now he’s attacked Iran, unprovoked. When the terror attacks come, and they likely will, we will have Trump to thank. And the price of eggs.

You can say Trump bombed Iran for any number of more recent reasons but the reality is that he bombed Iran because in 2017 threw out the deal Obama made, specifically because Obama made it, and was completely unable to negotiate a better deal himself.

Amongst all the discussion of whether bombing Iran is permitted by the War Powers Resolution, don’t forget that it is absolutely illegal under international law. Among other reasons it was the wrong thing to do.

The stripes are pretty, the implications are very ugly. Temps from 1850 to 2024 for Portland, Manhattan, and the world. Wanna see what it looks like where you live? Check out: showyourstripes.info

Wish Trump was thinking this way about joining the Israel-Iran war.

This effort may not raise $723 billion, but it should raise consciousness

Firing up the meme machine:

The Trump Doctrine is grounded in three core principles: 1. Who can offer him the most money? 2. What does Putin want? 3. Squirrel!

a) excuse me while I recover from whiplash, and b) probably the only time I will ever be “published” in Science. www.science.org/content/arti...

Almost 1000 people out in little Berryville VA (population c.4500). #NoKings

This woman approvingly quoted Hitler on the morning of Jan 6 and also serves on the House committee that’s been looking into antisemitism on campus 👍

must be incredibly frustrating and disheartening to have federal funding that was promised to you for important work suddenly and arbitrarily ripped away
