I know the world sucks right now, but for the next week I’m going to be exclusively posting about my trip to Geneva for #IAVCEI2025. I’m presenting a poster on Thursday, and looking forward to a week of fun and cutting edge volcano science.

Greenland is right. We must help ourselves, because our administration has forsaken our global partners. We will pay for this folly for a generation.

Every year on MLK weekend, my Appalachian town is host to two dueling protests. Curious if other folks in the South have the same experience.

Watch the videos I’ve posted over the past month on the May 18 lahars. If you need a gut-check on what lahars can do, read about Armero, Colombia. They’re fast, destructive, and often deadly.
And it wouldn’t take a 1980-scale eruption for Rainier to send a major lahar downstream.

Nice summary of recent research building upon the important early work of Pat Pringle, an excellent geologist who's spent time with the US Geological Survey, the Washington Geological Survey, and now an emeritus professor at Centralia College.

If ICE goes to Philadelphia it's gonna be real Wile E. Coyote hours
I've heard rumors that Philadelphia is next for the ICE invasion after Minneapolis.
Maybe I'm wrong, but
1) More than 11% of all ICE agents are in Minneapolis, and they've utterly failed to pacify the city.
2) Philly is 5x the size of Minneapolis.
3) "Minnesota nice" is a thing. We don't have that.

The split between Independents thinking science is better now vs both Rs and Ds thinking it’s getting worse is hard for me to understand…
A new report finds that a majority of Americans think the U.S. should be a world leader in science, but Democrats increasingly believe other countries are catching up. Check out the numbers below and learn more in the story here: www.scientificamerican.com/article/amer...

I don’t think this stuff is recoverable. I think these are the crucial four years where we just cede all basically all green tech production to China.

Like 56% of Earth's volume is just largely a mass of nearly black bridgmanite and dark but iridescent ferropericlase.
A bit more than 5% is a mix of darkest purple majorite garnet and deep blue ringwoodite.
A little over 4% is a mix of dark purple majorite garnet and blue green wadsleyite.

Imagine the old oceanic plates descending through a green that grows first blue then steadily darker before plunging into a mass of black flecked iridescent.
Imagine the great plumes ascending from the core-mantle boundary through first an inky blackness, then steadily lightening blue and green.
