In recognition of us doing fuck all to reduce emissions, let me remind y'all that carbon dioxide removal (CDR) is useless unless we decarbonize drastically. rdcu.be/dbFbB

I don't understand why more roofs aren't white, let alone covered in radiative-cooling paint.

I wonder if estimates of the Earth's capacity for geologic CO₂ sequestration account for people's opposition to having it in their backyards. 🧐

I have a very funny audience that I can never make completely happy, but such is life for queer Christian clergy, I suppose - especially when you write about a mostly secular topic. Anyway, I wrote about what being queer and cycling have in common, inspired by the guy who called me a bitch earlier

Besides being racist and false, this suggests science is only carried out by a few geniuses who claim prizes, whereas in reality science relies on smart and diligent people committed to collaboration and discovery without special recognition.

It’s not the biggest problem with this idea but it’s dumb all around.

But China…

Some unhinged comments and quote posts on this. Machine learning with artificial neural networks has transformed the environmental sciences, and rightly deserved the 2024 Nobel Prize in Physics. This isn’t using a chatbot to predict hurricanes.

In addition to two fascists losing elections in Serbia and Brazil yesterday, Oxford Street in London was closed to vehicular traffic and transformed into a pedestrian zone. 🥳

Can’t wait to see this!

Lol. Fascist losers are poor losers.

Me storming out of the faculty meeting.

Reform and Tories have pledged to reverse ULEZ repeatedly.

My investigation for @nature.com finds a surge of open records requests from groups with ties to the energy industry targeting climate attribution researchers. They come as the field plays a growing role in lawsuits suing big emitters for climate-related damages. www.nature.com/articles/d41...

NEW: Ingram, Texas, was just rebuilding from a devastating flood when its tiny police department enrolled in ICE’s 287(g) deportation program. Within a year, cops would hand over the equivalent of 10% of the town. with @nytimes.com

@karenlloyd.bsky.social is a microbial biogeochemist who’s the Wrigley Chair in Environmental Studies and Professor of Earth Sciences at USC. She researches microbes living deep inside Earth's crust and ocean floor to uncover how life survives in extreme environments and shapes ecosystems.

@ghgpolicy.org is a Senior Fellow at the Kleinman Center for Energy Policy who focuses on evaluating the scientific integrity of carbon markets. He co-authored Making Climate Policy Work with David Victor.

No, climate change isn’t going to kill everyone by 2100, but that’s not the metric by which we should judge how bad something is.

The Exxon ad Exxon doesn't want you to see. New from Adam McKay @ghostpanther.bsky.social and voiced by Woody Harrelson.

JUST POSTED: A Russian energy giant has secretly moved to acquire a position in a massive Alaska gas project. Its part of talks between Witkoff/Kushner & Putin. But CEO of US company resigns after learning of Russian money in the project. A wowzer of a story. www.nytimes.com/2026/10/23/u...

JUST POSTED: Today at The NYT we are publishing a major investigation into how President Trump used his executive powers to expose millions of Americans to greater cancer risks. A six month-long investigation built on more than 10,000 pages of FOIA records. Read it www.nytimes.com/2026/10/24/c...

In the coming century, there will be very few people who have seen a coral reef or a glacier.

Our ability to attribute climate change to human activities. 🫠

We live in a simulation where everything is very stupid.

70 percent of the internet was vulnerable yesterday to very bad security flaws inside a coding language. Turns out, *one volunteer* is mostly responsible for maintaining that code & helping push updates. Yesterday Ondřej Surý saved the internet. So I called him up www.theatlantic.com/technology/2...

Of the 50,000 heat deaths in Europe in the summer of 2026, 32,000 were killed by fossil fuels. Meanwhile, $65 billion in windfall profits for five biggest oil and gas companies in second quarter of 2026. www.npr.org/2026/10/23/g...

Kudos to NBC New York for saying it without equivocation: "The US is to blame for the world falling behind in the fight against climate change."

Called it!

The CDC denied a request from California, Hawaiʻi, Oregon, and Washington to validate a high-volume measles test, citing “other priorities.” 🤨
