Unfortunately, I was not well enough to help and my youngest had to make his sign alone. But look how well he did! He’s excited to see others out today!

In like 2008 I was Cindi Lauper's stand-in on a music video. I ended up wearing a trash bag to stay dry while a bunch of sexy back up dancers gyrated under a huge shower behind me and Cindi Lauper looked on.

December 2025 through February 2026 was the 2nd warmest winter on record for the Contiguous U.S. according to Prism climate data. The widespread record to near record warmth in the west easily outweighed the cool temps in the east. 🔥🔥🔥

Trump’s ICE Is Quietly Stockpiling Weaponry—and It Should Alarm Us All In addition to staffing up at a furious rate, ICE and CPB are acquiring a vast cache of weapons from private contractors, new data reveals. This will not end well—or anytime soon.

Appalling: ICE and CBP contracted for $144 million in weaponry and accessories in Trump's first year, per data obtained by Sen Adam Schiff.

For ICE it's a fourfold increase, much of it for military-style weapons. A heavily armed secret police force. 1/

How to stop a dictator I spent months studying how authoritarians like Trump lose. The answer is shockingly simple.

I have spent the past several months studying the cutting-edge research on modern democracies that have defeated authoritarian leaders.

I've learned that the conventional wisdom on the topic is wrong — in ways that have clear implications for the US going forward

"Women adopt AI at rates 25% lower than men.

This isn’t a guess. It’s the finding of a Harvard Business School meta-analysis examining eighteen studies, over 140,000 participants, across multiple countries."

With the federal government poised to (illegally) kill off the EPA's climate authority, what has been an open secret is now the only game in town:

If you want to make progress on climate, you need to focus on the States.

Scientists thought they understood global warming. Then the past three years happened. The fastest warming period since 1880 occurred in the past 30 years, according to a Washington Post analysis of NASA data.

"We’re not continuing on the same path we had before. Something has changed."

A @washingtonpost.com analysis of a dataset from NASA, which it used to analyze global average surface temperatures from 1880 to 2025, shows the *fastest* global warming rate on record occurred in the last 30 years.

Oh.

The Board of Governors decided, unilaterally, that no published textbook in the field of sociology could be used in compliance with the law for an Intro to Sociology class. None.
Victor: There's not a single existing textbook on the market that could be used that would qualify under state law?
Zachary: Correct.
Victor: I'm sorry, that's kind of funny. Like, the absurdity of not a single sociology textbook getting past the censors. I mean, it makes me kind of proud of our colleagues, but...

I do want to shout-out my fellow sociologists, who have collectively created a discipline so woke that not a single one of our introductory textbooks can make it past Florida's censors.

Great work everyone.
