I was liking some music and then it turned out it was an AI band. It made me question my taste. It wouldn't be so bad if they would tell me who are the main real artists this AI was trained on. I have a feeling Summertime Sadness was part of the training dataset. youtu.be/TdrL3QxjyVw

People who want to understand why CO2 cools the stratosphere as it heats the troposphere, and why this increases instantaneous radiative forcing, should check out this new paper by Sean Cohen and colleagues. www.nature.com/articles/s41...

By the way, here is an excellent in-depth interview with @aoc.bsky.social that came out 2 days ago. She is impressive and would make an excellent President. www.youtube.com/watch?v=nbzY...

I agree that @aoc.bsky.social is one of the best communicators the Democratic Party has, and it is not just the style of communication, it is the content. And if you look at AOC's web site, her featured success is economic. She is an excellent strategist. ocasio-cortez.house.gov

The first step is to regain political power, and to do that we need to advance policies that help ordinary working people. Politicians need to genuinely work to improve the lives of ordinary working people and advance policies that ordinary working people will see as fighting on their behalf.

In an unprecedented move, the Trump administration has granted industrial facilities in 38 states and Puerto Rico a two-year reprieve from rules under the Clean Air Act. The president is considering exempting even more.

Please enjoy my soundtrack for Yann Le Bihan's Mandelbrot zoom video. www.youtube.com/watch?v=6mQB... I suggested this variant to Yann. I liked it because it is a bit more organic-looking. It is based on modular arithmetic. z[n+1] = z[n]^2 + (1 + n % 31) * c

War criminals, killers, murderers

Spiralling global temperatures (1850-2026) It is exactly 10 years since I first put this animated graphic of changes in global temperature online. #ClimateSpiral It instantly went viral. People watched it over and over again. It still offers the power to shock a decade on.

What you don't know, can't hurt them. (But it can hurt you!) www.theguardian.com/us-news/ng-i...

Our ways of thinking are not ready for this world of large language models. We want to say "you" when communicating with something that is responding with natural language even when we know there is no "you" there.

chief justice roberts doesnt want us to think the supreme court is political oh sorry, i dropped this

This essay attributes declining birth rates, in part, to the "shadow of the future" -- a perception that the future may be worse, not better, than today. Why is the richest generation in history failing to give people widespread anticipation of a better future? www.nytimes.com/2026/05/07/o...

The Project 2025 author is using millions of dollars in USAID money for his own security detail. It is estimated that 762,000 people have *already died* as a result of Elon Musk and Russell Vought’s obscene murder of USAID, including more than 500,000 children. Vought is a mass murderer.

I can imagine the vetting process: "Is Trump a pedophile?" "Does Trump have dementia?" "Are Trump's pardons part of a pay-to-play scheme?" "Did the Trump family and various hangers-on get their contracts and make their billions due to their business acumen alone?"

The Republican talking points now come directly from Putin.

"We can have democracy in this country, or we can have great wealth concentrated in the hands of a few, but we can't have both." –Justice Louis Brandeis Words spoken many years ago that are just as relevant today. We must continue the fight to get big money out of politics.

Unfortunately, it's very hard to change people's diets. Money doesn't do it, even when paired with education. A new study gave people $80/mo for produce and most didn't even use it. I wrote about it just today. www.washingtonpost.com/food/2026/05...

Rupert Murdoch's @wsj.com is saying 'more military strikes may be necessary' as they continue to dream of 'strategic victory' in the Republican war on Iran. Military strikes are always a choice, not a necessity, and strategic victory is not within their grasp. www.wsj.com/opinion/trum...

Americans spend about 3.5 times more on health care than we spend on food (5% of GDP vs. 17 to 18% of GDP). Cheap junk food costs less now, but costs us more in the long run. Spending more now to buy healthier food, over time, saves money and lives.

🚨 NEWS: The U.S. Court of Appeals for the Fifth Circuit just rolled back nationwide access to the abortion pill mifepristone—BLOCKING telehealth prescriptions and mail delivery allowed under a 2023 Food and Drug Administration policy.

When Republican US Senators facilitate brazen disregard of the law, we get a Republican regime that brazenly disregards laws.

New Banksy just dropped and it's fantastic.

🚨BREAKING: Louisiana officials made clear Thursday that the state’s primaries will be postponed so lawmakers can draw a new congressional map in response to Wednesday’s Supreme Court ruling that gutted the Voting Rights Act. www.democracydocket.com/news-alerts/...

This @carbonbrief.org explainer on the Atlantic Meridional Overturning Circulation (AMOC) is very good. Useful for experts and novices alike. Kudos to @ceciliakeating.carbonbrief.org, @tomoprater.carbonbrief.org and @kerryanncleaver.bsky.social. interactive.carbonbrief.org/amoc-explain...

We (the mainstream press) don't talk nearly enough about MAGA white supremacy www.kcra.com/article/us-r...

Trump: "Global warming -- we're actually cooling as a planet"

Changes in the Indian monsoon rainfall are associated with the cold blob in the North Atlantic. New paper by Mahendra Nimmakanti, currently at Indian Institute of Science (Bengaluru). We hope to bring him to Stanford when his visa situation resolves. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

What are the most important peer-reviewed climate or sustainability studies over the past few years? What recent papers should we be sure to be reading? I am surprised by the lackluster response to this query. Does that mean there haven't been many important recent studies, or are people just shy?

U.S. President Donald Trump has fired all 24 members of the National Science Board, the body that oversees the National Science Foundation. https://scim.ag/4cxQWhl

What organizations are keeping track of actions like this, and identifying people who should be (re)appointed to reconstitute such boards if/when the Republican regime gets removed from power? Who is doing this? Do such efforts exist? Are they sufficiently funded?

The Republican regime is a collection of killers and murderers. Calling them war criminals, while accurate, puts too much of a high-tone gloss on their deeply repugnant and immoral actions. www.nytimes.com/2026/04/25/h...

Seeking thoughtful suggestions. What are the most important studies of the last several years that everyone working in climate or sustainability should be aware of? We would like to develop this list both for our own reading group and as a service to others.

Cherry trees in Kyoto. Not a subtle signal.

I just assumed that this was a parody account, but "President Donald J. Trump is Accelerating Treatments for Serious Mental Illness" is a real White House post. They were talking about other people's mental illness and assumed we would interpret their post that way. They are living in a bubble.

The 50% of people earning below median income pay only about 3.3% of the total income tax burden. The Democrats should announce that they will get rid of income taxes for the bottom 50%. A modest increase in taxes on highest earners would make this revenue neutral. www.nytimes.com/2026/04/19/b...

If in proportion to population, this would be equivalent to the United States regularizing 3,500,000 undocumented immigrants.

In the Venn diagram of humanity, the set of people who are ready to give advice intersects with, but is much larger than, the set of people who know what they are doing.

YouTube is now banning the Iranian propaganda Lego videos. Google changed their map to show "Gulf of America" on day 1, so it is not overly surprising. The Republican regime has both the carrot (your tax $$$) and the stick (anti-trust actions). www.aljazeera.com/news/2026/4/...

Interesting perspective. Stock market prices do make sense if you consider the skewed incentives created for politicians. The stock market is priced high because traders assume politicians will prioritize keeping stock market prices high over other social goals. www.nytimes.com/2026/04/18/o...

Remember when the biggest Presidential scandal was wearing a tan suit. Republicans were livid.

Ukraine built more than 10,000 drones per day in 2025 and will be building nearly 20,000 drones per day in 2026. www.globaldefensecorp.com/2026/01/30/u...

Trump apparently believes governmental officials routinely engage in grift by acting as project managers for real estate construction projects. A bit of projection going on here, methinks. apnews.com/article/fede...

We have a new paper finding that parabolic trough solar thermal collectors with molten salt energy storage could reduce both costs and GHG emissions in process heat applications, particularly in regions with strong solar resources and sufficient land availability. iopscience.iop.org/article/10.1...

The Republicans are very creative in thinking up new ways to destroy our country -- ways that nobody had considered before. Don't blame Trump. Trump is not smart enough to imagine such destruction. thebulletin.org/2026/04/its-...

These mask-wearing ICE thugs are the same people who refused to wear a mask during Covid.
