New essay out in @aeonmag in which I consider the deepest ways in which humans have changed the planet (hint: it’s not that super deep hole in Russia).

For @sciam I wrote about how powerful new x-rays and lasers are revealing an “explosion” of new minerals from Earth‘s mantle trapped in super-deep diamonds.🧪⚒️ https://t.co/rS3t05NXDY

We figured out who’s on the NYC council’s informal but powerful Budget Negotiating Team and we tried to ask them about it yesterday - to no avail! With ⁦@Annie_McDonough⁩

I say “symbolic” because it’s a way of taxing a subset of the rich (many of whom conveniently live elsewhere) without pissing too many rich people off. 🧵

The martian atmosphere is currently 200 times thinner than that of Earth. A 3 billion-year-old sandstorm recorded in the rocks could be the first direct evidence that wasn't always so.

A billion years of missing time continues to confound geologists. For @ScienceMagazine, I covered a new find in northern China that complicates debates on the source of the Great Unconformity:🧪⚒️

Seismologists played a key role in establishing bans on underground nuclear blasts — those bans may be starting to break down. Read all about it in my here newsletter: 🧪https://t.co/0TIqEk6GPj

Researchers "overjoyed" #NASA is going to move forward with two new $355 million Earth science satellites. One watching stratosphere, one watching ice/forests. My latest for @ScienceMagazine:

My latest for @ScienceMagazine: the plume of hot rock beneath Hawaii may have split in two deep in the mantle. Tens of millions of years from now this could lead to parallel island tracks above the hotspot.🌋

Seismologists use 5000+ earthquakes to detect sunken slabs of ancient tectonic plates flowing along the edge of Earth's core. My latest from #AGU2025 for

Some debate takeaways from @SahalieD, @Annie_McDonough and me: https://t.co/FRPBWHdtwH

Can fuel made from aluminum scraps supply the clean heat industry needs? For @techreview, I got a sneak peak of Found Energy's largest aluminum-water reactor to date.

What do climate scientists really think about solar geoengineering?

For @newscientist, @tinymaddie and I surveyed 120 IPCC authors about their attitudes towards solar geoengineering given failure to slash emissions on time. The results were surprising: https://t.co/WWpfqN0NUv

She had zero campaign experience before she masterminded Mamdani's June victory. Now everyone wants to get in touch with Chief Adviser Elle Bisgaard-Church.

Over the past two years, the land carbon sink appears to have weakened dramatically, driving the largest one year jump in atmospheric CO2 on record in 2024. Is this the end of the land carbon sink? I asked around for

Scary news for West Coast friends in my latest for
@ScienceMagazine. Disturbed ocean sediments off California suggest big earthquakes on the Cascadia fault can trigger big quakes on the San Andreas. The "Big One" could well become the "Big Two"...
