A fundamental tension: Robotaxi services can make the most money in dense urban neighborhoods—which are precisely the places that need them least.

Please read this extremely thoughtful & careful post on Tim Walz, Anne Frank, & the US Holocaust Memorial Museum from Martin Shuster, philosopher, Isaac Swift Distinguished Professor of Jewish Studies, former Holocaust Memorial Museum Fellow, & scholar of genocide, the Holocaust, & authoritarianism:

NEW | India is forging a different #energytransition path to China 🇮🇳⚡ Where China built first on coal and gas, India is taking a shortcut — using cheap solar to meet rising demand, relying far less on fossil fuels, and electrifying transport earlier. https://loom.ly/UFDLamw

A timely (long) read, both because of the birthday last Thursday (see below), and MLK day on Monday, and because the thoughts on non-violent protest against 'legal' injustices are very much on-point also with respect to the current situation: www.africa.upenn.edu/Articles_Gen...

The US is a great place to live for the super rich and super famous. For everyone else, plenty of other places would offer a better life. And yet, a big chunk of the latter group doesn't demand better from the US, because the former group convinced them that they too could be rich or famous someday.

Peaceful protest in DC right now

There is a growing network of faith communities across the US who are organizing & speaking out against the Trump administration's use of government powers for cruelty and repression. Tender green shoots of civil society resistance, but important ones.

So when authorities say “she tried to run over an officer,” that is not a neutral description. It is a claim of intent that can be used to justify lethal force after the fact. When the state kills first and invents the threat afterward, it is not policing, it is death squad behavior. /end

🧵In my expert opinion as a researcher of vehicle ramming attacks, what has been publicly described in the video evidence does not support the claim that Renee Nicole Good was attempting a deliberate ramming attack when she was shot in Minneapolis on January 7, 2026. 1/7

I just actually read the news for the first time in a week. Do not recommend.

Days start getting longer on Monday

For everyone traveling home from #AGU25, here something fitting to listen to, the final message dovetails nicely with one of my highlight take-home messages from this year: "If you don’t stop, they really can’t stop you." bsky.app/profile/agu.... And if you need a perfect nerd present:

On #AGVTV at #AGU25, Dr. Melissa Kenney and I talked about the opportunity for the entire scientific community to contribute towards climate assessment research. Submit your papers at USclimatecollection.org. youtu.be/7Kb-hfwIUxQ?...

Summary of the news today

Some of these redactions are almost like modern art

Shout-out to the bagpipes player welcoming attendees to the last day of #AGU25 in New Orleans

Definitely going to this dance today. From 8-9pm there is a beginner lesson, which is a great way to get ready for the dance if you haven't done it before. The social dance starts at 9, and will be with live music. Walkable from #AGU25 . www.maisondupuy.com/live-music/ www.maisondupuy.com/dining/

Still not sure who did this, but it’s really good advice for cities.

Happy to see this paper out - engineering estimates of company-level stranded assets implied by a 2 degree temperature target derived from ownership of individual energy assets. Congrats to lead author Robert Fofrich and @stevenjdavis.bsky.social

Glad to see this is happening! It's important that scientists *other* than those chiefly working on climate/weather speak up. Step up to the bully pulpit Geophysicists, Earth Scientists, Space scientists, Geochemists ..., #AGU25 #NCAR

This week CGS researchers are at #AGU25 to share research from our modeling and Indonesia programs. Learn more about how CGS's modeling and country climate work to support climate ambition in the NDC process: country-ambition.cgs...

Nice sunrise today to #AGU25 in New Orleans. If you want to hear about the economic impact of the rise of low cost electric vehicles, go to room 271, session GC22C from 10.30am-12 today

*Busy* Monday for me at #AGU25 NH12B-05 11:12-11:22 Applying the Swiss Cheese Model to Wildfire Risk Management in the Built Environment TH15B 6-7 Town Hall Hurricane Katrina 20 Year Later then RUNNING to Atmos Science section Student/Early Career mixer to talk cat modeling 7-8:30

Any lindy hop dancers 💃🕺 who go to #AGU25, and are on bluesky? There seem to be 2 live music events this week, tonight (Sunday) at The Allways Lounge (45 min walking from NOMCC, see below) and Thursday at Maison Dupuy (29 min walk, www.wwoz.org/events/1276446). Let me know if you go!

Heading to #AGU25? Here is a 🧵 of some useful resources to keep in mind! Be sure to check the meeting app "Helpful Information" section for the most up-to-date details & room numbers. 📸 Need a good indoor professional photo? Visit the Headshot Lounge, M-Th, in the Exhibit Hall. 1/🧵

Train travel also very convenient in that you can continuously post while traveling... that is a minus for the road trip option (although with an EV, the few extra minutes while stopping and charging help, I used all of those to text with friends and family...)

The article doesn't say it, but this cool solar forecasting software uses no large language models, the thing people usually think of when they hear "AI." It uses a fairly simple convolutional neural network that's readily trained on a laptop. No data centers or LLMs involved. Research paper here:

First ride in an electric taxi powered by Brazil's very clean electricity (see country-ambition.cgs.umd.edu/brazil#elect...). Just wow on how much space this offers inside for what from the outside even for European standards is a compact car. Very cheap according to yhe very friendly Rogerio 1/2

China's formal submission of its new climate targets leaves out the commitment made in 2021 to gradually reduce coal consumption in 2026-30. It does reiterate the commitment to reduce carbon intensity, which is currently badly off track, but doesn't provide any progress update.

Some much needed good news. “Jamaicans Have Been Turning to Solar Power. It Paid Off After the Storm.” Guft link: www.nytimes.com/2025/11/08/c...

Here is an embarrassing graph I have just made for a report. Fun fact: in 2020/21 Indian Railways added the equivalent of the UK’s *entire electrified railway network* (over 6000 route kilometers!) to their own electrified network - and then did this again in 2021/22 …and AGAIN in 2022/23! 🤯

Hey all you might want to check your "require alt text" setting - mine got turned off and it sounds like it's happened to others, too (presumably with recent updates). And if you've never done this, now's a good time: Settings → Accessibility → Require alt text before posting

🚨Excited to share our new paper "Dirty talk: Media discourse and the struggle over South Africa’s coal transition", published today in #ERSS @elseviersej.bsky.social with my great @pik-potsdam.bsky.social colleagues Charlotte S. Bez and Giacomo Raederscheidt. A quick thread 🧵1/

We're looking for a postdoc for our new project on forecasting technological change - more details below

Good to see that China has now officially submitted its NDC with 2035 target, though the targets are still disappointing, see e.g. our analysis bsky.app/profile/chri... Anyone aware of a good English translation? @drsimevans.carbonbrief.org @laurimyllyvirta.bsky.social @carbonbrief.org

Sales of non-diesel heavy trucks in the Chinese domestic market reached 57% of the total in September. LNG truck sales are still doing well, but the growth is largely in battery trucks.

The economic case for methane action is clear. - Global methane abatement yields large net global economic benefits. - The benefit-cost ratio of methane action is at least 3—rising to more than 6 when health cobenefits are included. www.science.org/doi/10.1126/...

Great work by our own team Canada, Kowan O'Keefe and Xavier Nelson-Rowntree. They show how Canada can overachieve their 2035 NDC ("Mod Amb"), but also discuss in detail the political difficulties, and crucial impact of whether regulation changes favor fossils or mitigation technologies. 1/2

Nice to hear someone take these loser actions, signs of incredible weakness rather than strength with humor...probably an attitude that can be helpful for many of us

A billionaire who thought we shouldn't give the poor free COVID vaccines, and hung out with Epstein, wrote some weird, vague stuff about how climate change "isn't that bad" and now the media is covering that rather than a record climate fueled hurricane. The age of oligarchy sure is exhausting.

Climate change DEFINITELY affects hurricane: STRENGTH: Warmer water is hurricane food RAINFALL: Warm air holds more water vapor SURGE: Warmer water expands, warmer ice melts, sea levels rise PREDICTION: hotter seas mean faster intensification

The DOJ is investigating unusual NBA prop betting, but it seems to me that insider trading coming out of the White House is a much much bigger problem.

Carbon neutrality doesn’t always lead to decarbonization. But who is decarbonizing? We looked at >600 US colleges and universities and found 7 that have decarbonized direct (Scope 1) emissions by at least 50% (usually with ground source heat pump networks). This is possible folks! 1/6

As someone who will prob. spend the rest of this week on social media being the "decarbonize your scope 1 emissions" guy, I'll just share this figure from @carleton.edu and say that schools also need to look for impact via their scope 3 emissions.
