Big Meadows was dammed to form Lake Almanor with Kohm Yah-mah-nee (now called Mount Lassen) in the background, with its first layer of snow for the season.

I'm realizing that I really need to understand the grandfathering provisions for post-catastrophe rebuilding in California. I do not understand why rebuilt homes in Greenville are not built to the WUI code and exactly which elements they were exempted from. Putting this on my homework list.

California insurance town hall this afternoon - just catching it after getting home from inspecting homes for wildfire risks. But not only do I talk about preventing home ignitions, I share the good news that home hardening increases your home's chance of surviving by a whole lot!

Why banks’ credit risk models are blind to climate

18% of banks integrate climate risk into their internal ratings-based models

credit risk and climate risk models are built on different logics

Unless supervisors adapt, these models will remain blind..

Terrific investigation by the @houstonchronicle.com finds that 20% of residential properties built since Harvey in greater Houston are in a mapped floodplain, 57,000 in-all. www.houstonchronicle.com/projects/202...
65K Houston-area properties have been built in floodplains since Hurricane Harvey
Houston’s relentless push into new suburbs has overlooked flood risks, putting tens of thousands of families in harm’s way.

This is center stage in the ladies room at work, about 6 feet by 8 feet big. I am a RCRA-CERCLA gal, not a NEPA gal, but I venture to say this is harder.

Here’s a great summary of how things are going in the world of forest fire mitigation at scale. I can confirm that reporter Jane Braxton Little did her homework on this one. plumassun.org/2025/09/21/u...

I was invited to provide the entertainment at the annual luncheon for my mom’s service club. I’m working on a short routine that involves the history of the violin and how both my sister’s ex-husband and current husband happened to be right where the Fly Fire started and merged with the Dixie Fire.

I've been monitoring FEMA's processing of disaster declarations after a long pause in the spring. This is the time of year when we start to get an uptick.

Lightning storms in Northern California - my cozy vibes consist of nonstop scanner traffic over the Tahoe, Plumas, and Lassen National Forests while I monitor @weatherwest.bsky.social Daniel Swain’s livestream. And I’m glad I jumped on my bike to get home before things got crazy.

The Los Angeles Fire Human Exposure and Long-Term Health Study continues to share good insights into physical and chemical conditions post LA Fires. Hexavalent Chromium data release aligns with my experience around hazardous waste incineration and ash management.

New LA Fire HEALTH Data Brief: Chromium-6 detected in air near LA burn zones - LA Fire HEALTH Study
Air quality monitoring in the Eaton and Palisades fire areas in March and April found elevated levels of chromium-6 (also known as hexavalent chromium, or “hex chrome”) in the air. […]

Author Lyndsey Gilpin did a great job with this guide! A fire burned nearly a million acres in my community, and I volunteered to set up a long-term recovery committee as part of the FEMA major disaster declaration. I was new to the entire bewildering process; learned all this from scratch!

#NTSB hearings today are as interesting as ever. But has anyone else noticed the snazzy new NTSB staff shirts being sported by everyone from Chair Jennifer Homendy on down? It definitely gives a very different vibe to the proceedings. Interesting #fashion choice to signal “we are public safety."

Wow—there are reports on Japanese television of at least four whales having washed ashore on the coast of the Chiba prefecture following the earthquake in the western Pacific:

Explaining the difference between a 3-foot tsunami wave and a 3-foot coastal wave is one of the hardest things to explain to island folks. I didn’t truly understand it either until I watched on live TV the tsunami inundating the Japanese coast in 2011. Unstoppable. Inundation. #tsunami
