A great update on the best way to scale up solar radiation management. Keep a lid on extreme temperatures, stabilize the ice sheets, bring down CO2, avoid deleting all the coastlines.

Why are people against self-driving vehicles?
Tragic news today: the eminent historian Gordon S. Wood was struck and killed while walking in the Shaw's plaza in East Providence, his family confirms to me. No comment from Brown yet
Wood was just featured in Ken Burns' American Revolution documentary wpri.com/news/local-news/pro…

I was at CAA to pitch Jared Leto. He was there for a fireside chat with Justin Kan (my Partner at YC who told me to come) about how celebrities should invest in startups, but Leto just bolted after the chat. I looked into the crowd and saw Matt and pitched him on the spot.

I was once pitching in a board room at a top 3 VC firm for a $15M Series A.
12 people in the meeting. One of the GPs fully fell asleep. Out cold for 30 minutes. Nobody acknowledged it. Everyone just kept going.
I kept presenting my Series A slides to an unconscious man in a Herman Miller chair and somehow that was considered normal. That's venture capital.
You might fly across the country to perform for people who may or may not be conscious.
It's a dance.
And sometimes you lead and sometimes you follow and sometimes your partner is unconscious.
If you're raising right now, just know: every founder has a story like this. The process is weird. The power dynamic is weird. You're not crazy for thinking it's weird.
No one talks about it because they want to continue raising. But I'm happy to stick my neck out there.
It is weird.

Is there a place in SF proper where you can park an 25 foot RV and live in it for $1,000/month?

The climate version of this is academic experts who correctly identify the problem, then immediately pull the degrowth lever.
But humans don’t scale sacrifice. They scale better technology.
If your “solution” requires billions of people to accept a worse life, maybe the random guy online asking for 10x better tools has a point.

Imagine spending your whole life becoming an academic expert. Then a random guy online tells you that you are wrong about your own field. And he's right. But you can never admit that. Because it would mean admitting that your life was a lie. That is the dilemma of many academics.

For my right winged followers, it doesn't really matter if you believe in global warming or not. There are millions of people who are currently located close to the equator feeling the full force of what you don't believe in. Guess where they're going to go once it feels too hot? Let's cool things down and not create climate refugees if we can for less than $6 per American per year.

So far, 3 net new sales from this podcast with apparently 10 million listeners each week. Surprisingly, the coverage is pretty positive. marketplace.org/episode/2026…
What do you think is going on @lulumeservey?

NPR might come out to a balloon launch, again. Cool.
But here’s the problem: legacy media is Boomer media.
We’ve already done the press — ABC, BBC, TIME, NPR, CBS, USA Today, CNBC, Reuters, WaPo, WSJ, FT, you name it. The script never changes:
“look at these weird tech bros”
vs
“concerned scientists who want bigger modeling budgets and more model UN cosplay”
Outcome: great B-roll, almost zero customers. Receipts:
docs.google.com/spreadsheets…
So what’s the rational move with @kairyssdal?
Do we keep supplying free content so Boomer audiences can feel morally superior about being outraged at the only people trying to cool the world they heated… or do we say “no thanks” unless the story is actually about what matters — people buying real cooling instead of another vibes-only climate sermon?
cc @lulumeservey lulu-one-kenobi, you’re my only hope.

Eli Lilly has done it.
They've gone and made what seems to be a powerful, permanent gene therapy for LDL cholesterol.
That means they'll be able to effectively prevent most heart disease with a single infusion!

Termination Shock.
Stop a statin and your LDL cholesterol rises 30% in four days. Nobody writes a WSJ feature about it. Stop certain blood pressure medications and your BP can spike within hours. Nobody calls it a design flaw.
Levothyroxine, antidepressants, insulin, metformin, antihistamines. Chronic treatments for chronic conditions, and all of them stop working when you stop taking them. None of them generate think-pieces questioning whether patients should have started.
The AMA classified obesity as a disease in 2013. Thirteen years later, it’s still the only chronic condition where “you have to take it forever” is framed as an argument against treatment rather than a description of how medicine works.

the heat will kill you first
Climate activists have spent decades shutting down nuclear, blocking clean energy transmission, and trying to ban research on cooling the planet... but the movement that wins the next century will be led by the people doing the work, not those protesting it. New essay out today👇

Like seriously: how transparent has Israel been about its nuclear program?
Now we’re supposed to trust a group of former nuclear scientists from that same national-security culture to become the global leaders in controlling how much sunlight reaches Earth?
That seems politically explosive.
Solar geoengineering is already one of the most contentious technologies imaginable. It affects the whole planet. So legitimacy cannot come from a small group of experts, a private company, or one desperate government writing a check. It has to come from radical transparency, public scrutiny, and earned trust.
That’s why I think @MakeSunsets is the better model. We have been transparent from the beginning about what we are doing, what we are releasing, why we are doing it, and how we think about scale. You may disagree with deployment, but at least the public can see the work, scrutinize it, criticize it, and force the conversation into the open.
For a technology that could affect global sunlight, that matters. A lot.
May 21
Depends. But the bigger question is: why hide it until now?
Why not disclose, as early and clearly as possible, what material they intend to put into the atmosphere, at what scale, and under what conditions?
What I still don’t understand is their thesis that deployment only happens if a government pays for it. Any government willing to partner on this would have to be desperate enough to attempt reflecting 1–2% of the Sun’s energy back into space, while also being willing to absorb massive domestic and international backlash.
That seems politically unrealistic without first earning public trust. You need buy-in from ordinary people before deployment, not just approval from elites or a single government. I don’t think this can succeed as a purely top-down project.
And that’s before you even get into the geopolitical issue of where this technology is being developed and who the rest of the world would trust to control it.
