The effective federal corporate income tax rate: 1950: 50% 1990: 25% 2020: 13% Stop asking "but how we will pay for it?" Restore the corporate tax rate. That is how we will pay for it.

Excellence in academia is like a river. Great people often flow from place to place. But the environments they flow through are constants. Proud that former @dornsife.usc.edu Prof. Yu Deng was recognized with a Fields Medal today for the work he did here @usc.edu www.nytimes.com/2026/07/23/s...

No, I don’t *think* the national Climate Assessment is working as intended, but I do *believe* it can be fixed. And I am *certain* Matthew Wielicki is the wrong person for the job. That is unless you’re a #climatechange denier like Donald Trump. Then he’s the perfect choice.

The National Climate Assessment is broken – appointing Matthew Wielicki to lead it won’t help

What communities and businesses really need is information they can act on, with examples of what’s worked elsewhere and why – and what fails.

We've learned since Trump took office in 2025 that tariffs are simply passed on to consumers. This is great news for me. I'm an export from Canada to the United States, so could someone please let my employer know that my salary should immediately increase by 50%? Thank you for your cooperation. 🇨🇦

Trump to Impose 50% Tariff on Many Canadian Goods

The administration will use an untested legal provision to put significant duties on Canadian exports, reigniting a clash with one of America’s biggest trading partners.

Remember: Democracy isn’t just about creating rules and institutions. It also relies on the unwritten traditions and norms that people choose to follow: rejecting false populism; a media free from intimidation; sharp self awareness; humility and compassion; valuing betterment over power. #America250

Yes I know that the world still needs #fossilfuels and, yes, I also rely on them even though I work on and care about #climatechange. But, want to know what the world, and especially #business leaders, need even more? Honesty and guts. I wrote about this in my new article for @theconversation.com.

Longtime Exxon CEO Lee Raymond’s legacy of climate denial and misinformation lives on – a psychologist offers ways to counter it

At the heart of combating misinformation is critical thinking and recognizing when you’re being spun for corporate profit.

"Two solar facilities built on rehabilitated agricultural land were restored with native plants. Argonne researchers observed pollinators thrive." Solar power, when smartly built, can improve agriculture *and* provide clean, pollution-free, low-cost energy. www.anl.gov/article/inse...

This is what happens when a company owns too much of our lives. #Amazon drops a movie by an acclaimed creative team about Sam Altman because they struck a bigger deal deal with with #OpenAI. In effect, OpenAI was able to nix a project in the entertainment division by paying 💰💰💰 on the AWS side.

Iran peace “deal” is poised to restore Obama-era JCPOA; also offers a major injection of cash and economic power to a government that has acted with impunity toward its people, especially women and intellectuals. Doesn’t feel like a win. Feeling awful for my Iranian colleagues and students today.

To my colleagues reeling from the #Canvas #cyberattack, I empathize with your frustration. I'll also offer a potential solution: Dump the tech. This semester, I almost completely ditched USC's online "learning" platform (Brightspace) in favor of good, old fashioned person-to-person contact.

According to reporting by @theguardian.com, Orbán has conceded to Péter Magyar and the Tisza Party. After 16 consecutive years, Hungary will have new leadership, which is quite astonishing. Also astonishing is the clear and significant majority claimed by Tisza in a heavily gerrymandered country.

A fun fact about me: I’m a Hungarian citizen and could vote in the election happening in Hungary today. I haven’t supported Orbán or Fidesz since his first victory on an anti-Soviet platform in the late 1980s. In my opinion, Orbán and Fidesz have become poster children for government corruption.

Today’s NYT article is going to make a lot of my climate science colleagues angry and worried. Please remember that, yes, most climate deniers are Republicans. But, most Republicans are not climate deniers. The only way we make progress is by working together.
