Opinion | This Is Just Who Trump Is

"For years, a cottage industry of political observers has contorted itself to obscure and occlude the obvious. That regardless of what others see in him, Trump’s entire political career...cannot be understood outside the context of his bitter, deep-seated racism." (gift link)

We are recruiting a postdoc to study wetland plant-soil-microbe interactions using isotope labeling in our greenhouse at LLNL with me and Erin Nuccio as part of a multidisciplinary project. Experience with wetland plants and SIP a plus. Please share!

Love it. My hometown.

Across America and the world, people are realizing it’s not possible to appease America’s dictator.

The only way to deal with him is to stand up to him — and the only way to stand up to him is by joining together against him.

It's time for a massive general strike across the country.

If you’re able, please support this verified GoFundMe for Alex Pretti’s family. And if you’re not in a position to donate, sharing it far and wide matters just as much. It’s at $300K and counting.

My sister-in-law's dad died last week, in hospice in the VA hospital in Minneapolis. I just learned Alex Pretti was part of his care team. They shot Alex less than 1/2 mile from my niece's house while doing the same observation work that my niece is doing. These are real people. Step up folks!

We’ve been in WHO since 1948.

This should be a national shutdown

If you missed it, the TL;DR is in my April thread below

The Epstein Files Transparency Act is a law, passed by Congress on November 19 with an overwhelming vote. Complying with it was not optional. The Department of Justice did not comply.

I want to make sure this is very clear.

Humans have emitted 2750 gigatons of CO2 since the industrial revolution from burning fossil fuels and land use change. To put this in perspective, this is more than the (dry) mass of all living things on earth and everything humans have ever built combined:

Remarkable how well earthquake alert systems work. We got ~5-8 seconds warning ahead of a 6.5 quake just now. Center was 400 km away, but still felt pretty significant here in CDMX.

I bet it’s hard to let it go. I’m glad I got to see it at the beginning. Gold standard of a well built, well run study.

As someone who often conducts fieldwork in remote places, I find it really irritating that many basic applications now require an internet connection to function.

Happy winter solstice! At last, we've made it to 'The Shortest Day' Dec. 21 is the shortest day of the year in the Northern Hemisphere. Susan Cooper, who wrote the solstice poem "The Shortest Day," collaborated with illustrator Carson Ellis on a new picture book.

President Trump thinks he can intimidate Colorado by shuttering NCAR.

It’s political retribution, Senator John Hickenlooper and I won’t stand for it. We are holding up the appropriations package to demand NCAR is fully funded.

The carbon and water footprints of data centers and what this could mean for artificial intelligence Company-wide metrics from the environmental disclosure of data center operators suggest that AI systems may have a carbon footprint equivalent to that of New York City in 2025, while their water footp...

There are many claims that AI is a “planet killing” source of greenhouse gases.

But is it?

This paper might be the most detailed estimate of the emissions associated with AI.

It suggests that AI could emit as much as 30-80 *million* tons of CO2 per year.

1883 wool quilt by Ellen Harding Baker: a vast black sky with a blazing yellow Sun at center. Mercury, Venus, Earth with its Moon, and Mars orbit it. Four clumps of objects beyond Mars represent asteroids. Jupiter shows its four Galilean moons, Saturn its rings, Uranus six moons, Neptune one. Top left: streaking Coggia’s Comet. Hundreds of stars dot the darkness. Hand-stitched by an Iowa mom.

Here's Ellen Harding Baker's "Solar System" quilt.🧪

This is the story.🔭

Back in 1876, an Iowa mom with 7 kids, E. H. Baker, decided that cooking & raising children wasn’t enough for her.

She started working on a wool quilt showing the solar system.

U.S. seizes ‘very large’ oil tanker off Venezuelan coast, Trump says The seizure was a significant escalation in the U.S. pressure campaign against Venezuelan President Nicolás Maduro and his country’s oil-dependent economy.

Just noting that no one is ever going to seize a tanker full of solar energy
