That's a wrap! - 50 hours of science + calling Congress - 300 letters given to Congress after a 250-mile walk We provided the templates and our viewers and supporters injected their voices. And like last year, we feel so uplifted by our community. Thank you for spending your time with us

If you’re not aware of it, please consider watching this livestream + taking action to protect the outstanding science and institutions such as NSF NCAR that are so valuable to society: wclivestream.com/act/ Now is the time to speak up and protect this public good for future generations!

Walking the last 2 miles of 270 with Syl Foisy and @zentouro.info for @wclivestream.bsky.social! 300 letters in support of science! 7 members of Congress (and more turned away) to greet us! I get to give a speech at the Capitol today!!! Let's gooooooo

on the @wclivestream.bsky.social, Rob Socolow just called the present moment an "anti-Sputnik" moment. I think that's a perfect encapsulation of this situation. Watch the livestream here: wclivestream.com

On The Climate Brink, I've posted my talk from the Weather and Climate Livestream @wclivestream.bsky.social on "How Science Works in Three Steps". www.theclimatebrink.com/p/how-scienc...

some very good graphs (and words) by @andrewdessler.com here

Never gets old. J-school essay topic: Is there any performance test for essentially life-tenure columnists? A limit on how many big calls you can get totally wrong, before they say: Hey, buddy, how about taking a step back for a while. Maybe a few reported pieces? Where you go out and ask around?

Check out the 2nd annual weather and climate livestream! Tune in to hear climate scientists & meteorologists talk over the next 50 hours about how federal funding has made incredible climate research happen. I'll be talking Tuesday at 1:20PM PT / 4:20PM ET :)

Heatmap News @heatmap.news republished my Climate Brink article on why the future of energy is hard to predict. Take a look! heatmap.news/ideas/future...

🚨 We begin our 50-hour broadcast today at 4pm 🚨 It's a showcase of incredible people and their phenomenal work- a celebration of the scientific community 🧪, defined broadly Use this link to subscribe to our YouTube channel and you'll get notified when we're live: wclivestream.com/watch

The Weather & Climate Livestream is back to remind us all of the *huge* range of services provided by federally funded science! I'll be up far past my bedtime at 12:20am ET on Wed to talk about how extreme heat seasons are changing around the world -- tune in this week and write/call your reps!

The Weather and Climate Livestream starts today at 4pm ET, and I am the first speaker, at 4:20! I'm going to talk about my own career, how it was enabled by many great people, federal agencies, and intellectual traditions, and the public benefits of the whole enterprise. wclivestream.com

Tune in today to the start of the weather and climate livestream! I’m presenting at 9pm eastern time on why plants matter for climate.

who did this? h/t @MLBMetrics on X

I'm really looking forward to attending this meeting on climate attribution science and the law (June 10-11). I'm on a panel about "Defending Science in the Current Political Climate". In-person attendance is full, but you can register to attend it online.

Meanwhile, Floridians are also losing home insurance bc of climate change related problems.

"The value of persons, however, does not depend on what they achieve or produce. There are rights that apply to everyone simply by virtue of being human, and no human power can legitimately deny or arbitrarily limit them."

Deniers spent years insisting "you can't get a grant funded unless you call climate change an imminent threat." Turns out that wasn't a critique. It was a roadmap. Every accusation, a confession — and now political appointees (might) get the final say on which research gets funded.

Over on his blog, Roy Spencer is arguing with people who don't believe the greenhouse effect is real. LOL 😂. I would normally pity the person, but it's Roy and he deserves it.

To a first approximation, when emissions stop, warming stops as @andrewdessler.com and @hausfath.bsky.social have shown www.theclimatebrink.com/p/climate-ch...

James Talarico: Ken Paxton is morally unfit for office. He’ll lie to you with a straight face. He’s failed the character test. He’s the most corrupt Attorney General of our lifetime. Those aren’t my words. Those are the words of Ken Paxton’s fellow Republicans.

On The Climate Brink, I write about how hard it is to predict the future of our energy system. The failure of past predictions should make us hesitant to put too much faith in future predictions. #energysky 🔌💡 www.theclimatebrink.com/p/nobody-kno...

“How much Iran will get away with, and how much humiliation the United States will endure, has yet to be ironed out by the negotiators, but the war is now almost certain to end with Tehran’s theocrats firmly in power,” @radiofreetom.bsky.social argues: theatln.tc/fNGBk4cQ

This is absolutely hilarious. Colbert’s Sudden Return to Late Night? It Happened on Public Access. www.nytimes.com/2026/05/23/a...

With friends! It *is* a lovely day Thanks to everyone who came to support us in-person this morning as we started our walk from NYC to DC!

Normie take, but Game of Thrones *is* a good analogy for climate change - not just because of the humans squabbling amongst themselves as their doom approaches, but also because the final season absolutely sucks.

this is very cool

Scientists: Please sign up! This is a great opportunity to both showcase your work but also, in concert with everyone else, highlight the entire field.

Yes, we are affecting the weather by emitting carbon dioxide and greenhouse gases. However, that’s a far cry from “controlling” the weather. The speculation that it’s 5G cell phone towers releasing particles is wrong in every way. factcheck.afp.com/doc.afp.com....

I wrote about RCP8.5 in one of the first posts on The Climate Brink. It may not be business as usual, but there are still good reasons to analyze RPC8.5 runs. www.theclimatebrink.com/p/rcp85-asks...

My latest screed on the besieged state of U.S. science. I connect it to a broader phenomenon, namely willful blindness to the value of government-supplied public goods. deepconvection.substack.com/p/wrecking-t...

Still thinking about this (from @ferrisjabr.bsky.social 's Becoming Earth): "a single gallon of gasoline represents 100 tonnes of ancient life, roughly equivalent to 20 adult elephants". I knew it was big, but never worked it out. A tank of petrol is a LOT of ancient life. +1 reason to electrify!

This is a good post from @janrosenow.bsky.social about the cost of electricity from renewables vs. fossil fuels. Do renewables make electricity cheaper or more expensive? open.substack.com/pub/janrosen...

can anyone explain why the 2026 prediction is so low compared to the 2023 and 2025 predictions (2024 is missing)? in the 2026 prediction, solar grows slowly after 2030.

These plots of actual changes in energy produced vs. what the experts predicted tell an important story. I've created updated plots, and you can get the code to reproduce them, or make other versions, here: github.com/aedessler/EI... #energysky 🔌💡

Every semester I do an anonymous survey of my class' political views. I did it at the beginning of the semester and then redid it survey at the end. Here are the end-of-semester results. Here is the political affiliation question, which yields results similar to the beginning of the semester:

I spoke with three infectious disease scientists about the connection between hantavirus and climate change, and how the rapidly-approaching Super El Niño could affect infectious disease spread this summer.

In the year 536 AD a massive volcanic eruption caused major climate change, forcing rats to cluster in human environments and leading to the first recorded epidemic of bubonic plague
