ICYMI: This is my STARTER PACK specifically profiling urbanists OUTSIDE of North America! If you love cities and want them to be better for people, please consider following these folks and orgs, and please share this pack as much as you can! Thanks very much.
A global network of urbanists shaping the cities of tomorrow. From sustainability to resilience and fairness, we’re all tackling the same challenges—and we have so much to learn from each other. As climate change and other crises intensify, sharing ideas has never been more urgent.

Great men& women are leaving us—a Great Generation of thinkers& doers. They leave behind giant shoes to fill and it’s now time for younger generations to step up. People like Alan fought for profound, positive change—change that we must defend & expand.
Our challenges are great, but so were theirs.

Posting tonight about great city-making books made me realize, to my shock, that I never posted about the deeply sad death this year of one of the greatest urbanists who ever lived— Allan Jacobs. Jake was a big hero of mine in my early life, who became an advisor & friend later on. A GREAT man. #RIP

If you’re frustrated with the Dems for caving, pls watch @lawrenceodonnell.msnbc.com explain what actually happened. He’s one of VERY few pundits who’ve ever been inside the LBJ room in the Senate, where key decisions are made. Things may be looking brighter than you think.

Cycling is healthy, fun, and one of the simplest and cheapest ways to fight the climate crisis.
More bike lanes mean safer streets, cleaner air, quieter neighborhoods, and even local economic growth.
Honestly, what more could we ask for?

It’s awesome to see this — but seriously, it’s so damn frustrating that we have to fight this fight in every city when the science couldn’t be clearer. Get the cars out, make more money for local shops, and build cities that are exciting, healthy, and happy for everyone.
It’s really important that #Vancouver’s Downtown Business Association, who were originally against bike-lanes, are now among their most vigourous supporters, because of ACTUAL EVIDENCE that they’re better for downtown business than any street parking they replaced.

Our greatest challenge is to awaken awareness without extinguishing hope—the very force that drives action amid accelerating climate change. Adaptation demands that we rethink old assumptions and rebuild societies that are more fair, sustainable, compassionate—able to thrive in the face of change.
This is the news I've dreaded all my life, and it's here: Humanity has failed to avoid dangerous climate change.

Dear people who don't live in the Chicago area,
Trump's thugs are practicing their violence on us before they apply it coast-to-coast. Get active now, while you can. Help us defeat the fascists and save our country.

The deeper issue is that city govs often overlook the real costs of inaction—investments that seem costly now but yield long-term savings or even revenues. For example well-designed social infrastructure reduces mental health costs and strengthens community cohesion & #resilience in times of crisis.
Many city halls are deep in budget-time. Some are pushing austerity ideologies, and are ignoring the difference between costs and cost-savers/value creators. Citizens, PAY ATTENTION, and never forget that the TRUTH about a city’s REAL aspirations isn’t found in its visions. It’s found in its budget.

We’re no utopia, and we’re far from perfect, especially in recent years. Frankly we should be doing much better. But we’ve generally made better city-building decisions emphasizing a city for people. Discussing our city-building with visitors often reminds me of how much we’ve done well. #Vancouver
My wife and I had a chance to spend a few days in Vancouver last year and let me tell you…
This city feels like it’s from an alternate reality where the people don’t prioritize greed and selfishness over empathy and community.
We went home incredibly jealous of… well, everything.

Fair point. However, most people who could be swayed by more media coverage already know enough about climate change and other elements of the #polycrisis to act. Yet despite that knowledge, they not only fail to act—they rarely even share their concerns or discuss the issue.

Brazil poured great diplomatic effort into forging connections and fostering climate networks, drawing on the local concept of mutirão. Adapted from Indigenous practice, a mutirao refers to a community coming together to work on a shared task, whether harvesting, building, or supporting one another.
