Short 🧵. Several folks routinely do a great job updating global mean temperature comparisons between observations & different model generations, which shows their impressive skill, but I think as a public communication tool downplays the explanatory and predictive power of climate science 1/

Anyway here's the real article, please share this one and not that one heated.world/p/charlie-ki...

Tens of thousands marched through Midtown Manhattan and the local paper of record appears to have ignored it. Way to go, @nytimes.com

Wait, it gets worse. The team of economists and researchers responsible for the USDA survey that measures food insecurity and hunger were put on indefinite paid leave today. www.wsj.com/politics/pol...

As the brother of an autistic American, as a person who worked on US scientific integrity policy at the White House, and as human being, I'm boiling at the RFK idiocy. And though I have little to offer beyond surpassing rage and national shame, I did smile at this statement from NYU's Arthur Caplan:

See also: med students. Can you imagine being in med school now? Surreal.

Update of perhaps my favorite global climate policy indicator: The production gap report. In fact, the gap between countries' planned fossil fuel extraction and global climate targets has widened. Turning the tide on these indicators is essential for climate policy success. productiongap.org

In 2024 the US economy was approx $29 trillion. Investing $7 trillion by 2030 over 4 years is about 1.75 trillion a year in data centers or 6% of the economy per year to…..meet AI demand for….what purpose exactly? To make more AI slop? Bubble, popping soon, it is.

Remarkable how persistent we were in ignoring these early warnings.

New report says, if rich countries want, they have more than enough money to fund climate action: $6.6 trillion annually oilchange.org/publications...

Saving America from Trump and preserving our democracy explicitly requires that people who voted for Trump change their mind. Which in turn requires that those who didn’t vote for Trump show grace and empathy to those whose change of heart came from being hurt by the guy they voted for…

There is no world in which it is normal for the president to publicly call upon his attorney general to hurry up and prosecute his political foes. It’s like the Watergate tapes but posted on social media. Let’s get a grip on what’s happening here.

“The first amendment is a series of concentric circles, beginning within your mind and then moving to your close acquaintances.” radiolab.org/podcast/27-m...

Media execs have fallen prey to a propaganda and harassment campaign that has completely divorced them from what people actually want right now. Both their insular information environments (group chats, podcasts) and ambient noise (Twitter reactionaries) have put them in a very stupid bubble.

An antidote to despair and cynicism -- academics studying countries facing autocratic takeovers document that more than half of these episodes lead to "U-turns" and more than 90% result in strengthened democracies. Up to us to make it so! www.tandfonline.com/doi/full/10....

Even before the AI bubble, energy was an immense puzzle

This is really interesting, first in its look at recent and current times - and the social changes - in Japan, and its discussion of a bit of social psychology. Thanks for the post!

In the Hudson Valley? Come to Vassar College to celebrate Sun Day, Sept. 21, 1:00 - 3:00. Come for a solar + EV powered musics, art, games, food and more!

Indeed. Earlier this summer, the White House did this to me, as a scientific expert source in media, and issued a formal statement regarding my personal campaign contribution history in an attempt to discredit my commentary on wildfire, climate, and federal policy. Yet more alarm bells ringing...

"China is the only large country driving the energy transition at anything close to the necessary speed and scale." It's also the only one whose energy transition is not hamstrung by reliance on the motive force of renewables profitability. Coincidence? I think not.

Live-posting #PlayEnergetic ! This is the 4th year I've had my climate solutions class play. The game gets so much so right - and it makes relations of decarbonization, affordability, grid reliability, community opinion, politics, policy intuitive in a way that all the readings in the world don't.

"Fascism is a temper tantrum disguised as an ideology" is a great line

Glad to see dozens of students at Vassar decarbonizing NYC this morning in @jeffsseidman.bsky.social's class. We can do this for any city, and now we have 1000 sets to distribute for New York. Ideas welcome! #PlayEnergetic

Probably because business as usual is easier. Simply stop insuring risky properties and keep making huge profits by investing the rising premiums, often in the very fossil fuel companies causing the problem

Here is my best guidance, rendered beautifully by the great John Lithgow. I first published these lessons nearly nine years ago, in late 2016. They open the twenty chapters of "On Tyranny: Twenty Lessons from the Twentieth Century." snyder.substack.com/p/twenty-les...

Overcrowded cells. Unsanitary conditions. Limited access to food and water. These are the conditions that ICE has created at 26 Federal Plaza, which eleven elected officials sought to expose. Instead, they were arrested. They must be released right now — and inspectors let in.

This is very good. The story on Kimmel isn't Kirk - it's the bribery and corruption of our media by the FCC & Trump WH.

x1000 this. for the list @jayrosen.bsky.social keeps

Seems really bad www.bloomberg.com/news/article...

We are excited to announce the release of the Environmental Hazard Adaptation Atlas, an effort to map ongoing and future environmental hazards and their impacts on society, and to provide up to date evidence on what policies and interventions work to reduce impacts: adaptationatlas.org.

We experience it, but we can't call it "involuntary degrowth," even though that's accurate.

Whenever I meet boomer/late genX Indian upper middle class elites, their utter disinterest in the costs of our connected lives of luxurious convenience is so pervasive. They simply do not care if the working class are suffering, & are never convinced the working class are working hard enough.

Bill’s exactly right. 99.9% of climate denial is solution aversion. They don’t want to fix it, but they know that saying “it’s real and serious but I don’t want to fix it” isn’t a great message. So they go with the smoke screen of science denial instead.

Grand Rapids celebrates being the first city to flouridate its water. But now other Michigan cities, and even Windsor, ON, are dropping the practice. The idea of *public* health is in retreat.

Will LLMs someday predict renewable electricity output, or guide dispatch decisions, as well as today's (far less resource intensive) systems? It's possible. Will the incremental performance improvement be worth all the pollution and power grid strains/costs from data center buildout? I doubt it.

Exhibit A holds all the cards at the moment, but Exhibit C can always come out of left field and back up Piketty

Exhibit A is in his own warped way trying to explain this to us, as the world's hardest working, most competitive, most anxious & wealthiest decarbonization entrepreneur bsky.app/profile/jenn...

There’s a once-in-a-lifetime opportunity for people to build on the rubble of what’s being destroyed before our eyes. Private corporations bending over to forcefeed everyone government-approved speech is evil and amoral, but more than anything this creates boring, inauthentic, unwatchable shit.

Continuing a theme, and offering material to @ghostpanther.bsky.social's notebook

Thiel's whole bet: well-educated Americans believe in nothing. Per Packer's book "The Unwinding," Thiel started out on Wall Street & it scared him. As he now wants to turn the US into Mordor, maybe his logic is, "I might as well rule, then." There is hope yet, though. Sleeping giant and all that.

When super moderate centrist shows like Kimmel and Colbert are being shut down you know we are chest deep in the fascist broth. What is SNL going to do? The entire foundation of that show for 50 years has been mocking whoever’s President.
