Speaking of Larry Summers.
Here's what he famously said about toxic waste and #climate breakdown.
What a di*k! 🤡

Also: a change in projections is not a change in emissions. It's one indicator of progress: but it's misleading to present it as the best, most reliable or most meaningful, or to centre it too aggressively.

If you want to argue some progress has been made with reducing greenhouse gas emissions - OK. But stop framing it like this. The precision of 2.6°C completely misrepresents the *vast* uncertainties when it comes to climate & social responses & dynamics.

Several States at #COP30 are feeling nervous this week. Turns out, clarifying your legal obligations is uncomfortable when you’ve been ignoring them.

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..

Wildfire-smoke-related deaths in the US could climb to 70,000 per year by 2050 due to climate change, study finds
The number of deaths from exposure to wildfire smoke in the U.S. could rise by more than 70% in the next 25 years. The human and economic costs involved would be astronomical, researchers say.

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.

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.

#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."
