@dangillmor Seems like it's peripherally about climate change, but it's mostly about the cost of rebuilding going up substantially and not being able to raise premiums to cover those increases as quickly as they have happened.
My guess is that the insurance regulators in California will eventually approve the requested rate increases and the companies will come back.
In a way, this means that the regulation is serving its purpose: it's keeping insurance profits low, as demonstrated by the companies being on the edge of exiting the market. If they were making money hand-over-fist, they wouldn't do that. But you can only squeeze them so tightly, before you need to give in and allow rate increases if you still want insurance.
But communities up in the woods in fire-prone areas are going to have some *astronomical* insurance premiums, looking forward.
