And LA is not a one-off - we're consistently losing a material amount of housing to wildfire in a state that doesn't have housing to spare

Absolutely fantastic study comparing anonymized outputs of climate analytics models.
Everyone loves to bag on flood (rightly so), but can we talk about how the spread here is "30mph breeze to Cat 5 hurricane" www.fca.org.uk/publication/... HT @ruarirhodes.bsky.social

If you want to see what a best-in-class climate scientist with a lens on geopolitics and energy can do in the financial sector - read Sarah Kapnick's new report on energy system politics for JP Morgan. A few of my favorite figures below 🧵1/ www.jpmorgan.com/content/dam/...

Curious about which fields poast the most?
Medicine / Social science / Environmental science / Biochemistry
Note that these aren't corrected for field size, so love the strong showing from earth science too ⚒️🧪

Super thoughtful research on the impact of mitigation strategies for reducing wildfire risk from @gollnerfire.bsky.social team. Good news: building level mitigation can do a lot. Bad news: #1 factor is structure density (SSD below) - hard to change and may get worse. www.nature.com/articles/s41...

Fires started on private lands and transmitted to public are more damaging than the reverse - relatively uncommon for destructive fires to start in public wildlands and spread to private communities. Fig 6 is esp striking.
