That's from a group of more than a dozen prominent climate scientists. Probably nothing.

Watch this from @techconnectify.bsky.social until the end. The first part is things you probably already know. But the call to action in the last part, even though it’s also things you already know, is good to hear.

NIMBYism and apartment bans are expensive.
In 2019, a study found that housing constraints resulted 36% lower GDP than if we had simply allowed enough housing to meet demand.

Not surprised that Trump is not actually concerned about affordability.
What's really scary is how many Democrats push the same nonsense.

Periodic reminder to Democratic Party electeds: preserving the patterns of segregation represented by single-family-only zoning and local control over land use is a page straight out of the MAGA playbook. Specifically, page 511.

Why do we require so many vent pipes for our wastewater plumbing?
While Europeans are stunned when they discover that an extensive network of vent piping is still required in most of North America, Norwegians having been scoffing at the rest of Europe for using a 4 inch (100 mm) single stack instead of a 3 inch (80 mm) for nearly a century.

I love this line.
This isn't mine, and I can't definitively find the original source. But I love this little bit of wisdom:
"If you're a fifteen-minute walk from a coffee shop, but the server there has to drive an hour to get to work, you don't live in a walkable city. You live in a theme park."

For all the fearmongering about capital flight from New York City, there’s an exodus few want to talk about: working people.
Sky-high rents and outrageous child care costs are already pushing families out of the city they keep running.
That’s what we have to change.

"Upzoning is destroying LA neighborhoods"
Oh yea? Here's the 1930 zoning map for this lot. It was zoned "B" aka "R4"
What did R4 allow in 1930? Any residential use "without limitation on the height or area"
This area has actually been DOWNZONED

Today on UCLA Housing Voice, I talk with @kevinerdmann.bsky.social about about the mid-2000s housing market pre-crash, resulting changes in federal mortgage lending standards, and their catastrophic effects on homeownership, rental affordability, and production. www.lewis.ucla.edu/2026/01/21/1...
Episode 106: Mortgage Lending Standards with Kevin Erdmann (Incentives Series pt. 8) - UCLA Lewis Center for Regional Policy Studies
We built too much housing in the mid-2000s, right? Kevin Erdmann says no, explaining how this misunderstanding is at the root of unaffordability today.

Throughout the Incentives Series we've been talking about the costs of being overly cautious, and I'd argue that restricting mortgage credit to such a large extent in response to the Global Financial Crisis deserves to go right to the top of the list. www.lewis.ucla.edu/2026/01/21/1...

If I'm being honest, the collapse of the post-Cold War international order and the violent occupation of an American city are making it difficult for me to concentrate on housing policy.

SO many of NYC's iconic buildings only exist because there were no historic preservationists around to block demolition of what used to be at the site.
If the city had prevented the razing of the old Schaefer Brewery a century ago we wouldn't have St. Bartholomew’s Church today.
