Every year or so, the guys from the tire shop behind our place change the mural on the side of their building. This new one isn’t quite finished but it’s a banger so far.

The giant blimp hangar at Moffett Field got a new skin, now it looks like something from David Lynch’s Dune movie.

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...
The weak land carbon sink hypothesis
Satellite-derived time series of vegetation carbon do not support a strong Northern Hemisphere net land carbon sink.

OK, these budget cuts have gotten ridiculous.

Just out: A new geodatabase of fuel treatments across federal lands—published in Scientific Data.

Whether you’re mapping change or assessing risk, TWIG shows when and where treatments happened.

Grateful to be part of a team!

Yup, full support here. SF has been in dire need and we finally got 33 of them this year.

There’s a widespread myth that Americans hate traffic cameras. It’s simply not true.

On the contrary, researchers have consistently found that Americans broadly support using automatic enforcement to curb crashes. And for good reason: It works.

Me, in Bloomberg 🧵
Automated Traffic Enforcement Is More Popular Than You Think
Cameras that ticket drivers who run red lights and speed are effective and widely popular with city residents. So why are they banned in so many places?

Oh, for sure. “San Francisco start-up says,” is basically code for “what follows is unsubstantiated hyped up bullshit.”

Did you know that many consider San Francisco's system of care broken?

People fall through the cracks, or only get care after they've lost their jobs or housing.

#sf, and the public, have an opportunity to transform that system for the better.

I'd just like to point out how weird it is that places with hundreds or even thousands of reporters — the NYT, WaPo, CBS, NBC, AP, etc. — are all getting pummeled on every major story by the dozen computerboys at Wired. To fumble the bag this consistently is, at some point, cowardice and a choice.
