Nearly every panel I spoke on this year ended with the same question: "What gives you hope?" My friends, that question expired years ago. (If you need receipts, my book Saving Us is literally a 300-page answer.) The real question is: How are you PRACTICING hope? Because Greta is right ..

just learned we won an award for our blog post about Tom Holland and stormwater management. remember, when you see an article about stormwater management, you repost it. i don’t make the rules.

It is genuinely incredible to me how much evidence there is to support investing in the public good and how much animus there is to do this simple, effective thing.

NEW: Epstein survivors release the most powerful PSA I have ever seen. Make this go viral so every member of the House of Representatives sees it.

“There’re about a thousand of us.”

The current trajectory of "AI" energy and water use also mean tech co.'s won't meet stated carbon-neutral & water-positive goals. And that's w/o considering the resource use in building data centers in the 1st place (the authors say this is outside their scope); with that data, the picture is Worse.

NEW: ‘Unlawful coercion’: Trump can’t withhold funds or demand payment from UC, federal judge rules. The judge has previously sided with UC scholars several times since June in halting Trump’s termination of science and health research funding. The latest ruling is arguably the most sweeping yet.

A new state-by-state evaluation of the projected energy and water use of "AI" data centers in the US. Looks… real bad. Like, "undoing tech sector climate gains" bad. Strongly recommends immediately ensuring any & all new "AI" data centers to run on existing & expanded renewables grids. Which… yeah.

NEW: Global fossil fuel use will peak before 2030 – unless 'stated policies' are abandoned Contra some terrible news coverage, IEA World Energy Outlook shows coal near peak, oil peaking by 2030 & gas by 2035 (see chart) What's going on? 🧵 + cool charts www.carbonbrief.org/iea-fossil-f...

I wish it were better understood that this is an act of mass murder akin to firing into a large crowd. Impossible to say specifically who will die as a result of this action, but certainty that it will be many.

Divvying up the dwindling Colorado River in a warming climate. Much of the river's watershed remains in severe drought, and its water is over-allocated. #copolitics

Brilliant new ad campaign I just spotted at the Southwark tube station in London.

Is this in U.S. news? #AcademicSky www.theguardian.com/us-news/2025...

"Under the deal, large cargo ships would have paid a fee if their CO₂ emissions exceeded a certain level. The standard would get stricter over time, encouraging the industry to move away from oil-based shipping fuel to cleaner options." THE LEADING SHIPPING LOBBY SUPPORTED IT

Scientists point to a long list of findings that emerged out of fundamental research, the type of studies the US government is cutting, and went on to change the world. Nature lists a few of their examples. 🧪

Look at this. The hurricane downed and washed away the vegetation. One of my students told me today that the soil of her dad's farm just washed away. He has no farm now.

NOAA cancels funding for data collection crucial to tsunami warning systems

Finally, some longitudinal data on faculty morale.

Just heard a story on NPR about how cops are now using genAI to write their police reports... so a mystery machine is now writing the fundamental base legal document that gets used in *any* legal incident... great

New #WomenLeadingOnClimate episode drops today! This week, I climate scientist @katharinehayhoe.com and I talk about how to talk to real people about climate in a real way that gives them hope & motivates them to act... Listen, share & subscribe. www.womenleadingonclimate.org/our-podcast

The government shutdown has put SNAP benefits at risk for millions of Americans. Travis Peters, an urban farmer in Detroit, is giving out free produce tomorrow 'If it's getting tight, my food is free. Don’t even sweat that'

Birds thrive after fire — but only where we don’t log the aftermath. In the Sierra parks, no salvage crews came through. Research shows post-fire logging turns recovery into decline. Snags aren’t waste; they’re home. www.sfgate.com/bayarea/arti...

AI chatbots are sycophants — researchers say it's harming science

The comments 💀

Estimated say there were 5.2-8.2 million people protesting so out of 347M we're between 1.5-2.3%. Getting closer, let's do this!! 💪

Research shows that it takes around 3.5% of the population actively participating in actions to bring about transformative change. Keep going! #upupup

Good evening. We estimate that between 4.2 and 7.6 million people turned out for the No Kings Day demonstrations held around the country on Saturday. This makes Oct 18 very likely the biggest single-day U.S. protest event since 1970. www.gelliottmorris.com/p/second-no-...

If you refuse to let the immigrants free, behold, I will plague all your country with frogs

Breaking: Today is officially one of the biggest days of protest in American history. Over 7 million Americans turned out to No Kings events to stand up against MAGA fascism.

not exactly a student of history, is he

And from image events, we get POLYSEMIC images that carry multiple forms of ideology into the present. Here, we have the convergence of Shepard Fairey's iconic HOPE poster for the Obama campaign with the frog icon from #NoKings. The is how you visually dismantle fascist iconography.

Don't mess with Chicago.

I don’t have kids, I don’t want kids, I don’t particularly enjoy being around kids. But let me be very clear and as unambiguous as possible: I STILL WANT MY TAXES AND SPARE GOING TO FEED KIDS, YES, 100%, YES.

Los Angeles came out in droves. #NoKings

reposting with alt-text Zero arrests by NYPD is actually astounding to me

I've never seen a mass movement like this in my hometown of San Diego. If this photo is accurate, this is historic. 😮

Thank you, South Korea we love you

Giant copy of the Constitution being carried down Pennsylvania Avenue.

I wrote several papers about how bad corn ethanol was going to be around 2010, so I am not surprised. We should always remind ourselves that biofuels are complements not substitutes for fossil fuels, b/c they are used in ICEs and have limited scalability. They are a big ag and big oil PR mechanism.

“American science, the gold-standard and world-leading science and innovation enterprise, is being destroyed….Congress has a rare moment of leverage to check Trump’s executive overreach and it must stand up and do so.” - @markhisted.org, NIH neuroscientist www.nature.com/articles/d41...

The tools:

“‘Thoughts and prayers aren’t enough… Mitigating these things—security cameras, security guards, school drills—isn’t enough. You have to act to prevent them’.… there is evidence that mass shooters tend to follow a common path to violence, that they leave signals of their intentions”🧪🛟 *gift link

Annenberg poll in April 2025: 7%pt increase (since Aug. 2023) in support for req'ing kids to have MMR vaccination to attend school. A lot could have contributed to this uptick since Aug. 2023, but recall April had TX measles outbreak (& others) plus RFK Jr.'s statements/actions about it. 🛟😷 medsky

Chronic underestimators, the IEA calls solar #1 by 2033—but they’ve never kept up with reality. 🚀 With 2025 smashing records & storage racing ahead, coal could be dethroned by 2027–28, maybe sooner. The sun isn’t waiting for forecasts by the fossil lobby. ☀️ #Solar #BESS #EnergyTransition #Renewables
