Buy flood insurance and if it gets too expensive, it might make more sense to move. I live in an area where flood insurance just skyrocketed and I think people are still hoping prices will go down somehow but I don’t think it’ll happen.
If you’re handy, maybe look into how to gut a house after a flood. Mold can do a lot of damage.
I don’t know if you’re in an area where flooding could be a safety issue but always follow local warnings/official’s advice. Property can be replaced, people can’t.
I think as humans we can engineer our way out of increasingly hostile weather but it takes an investment of time and money and our governments aren’t usually great at either.
Stop buying what shit? Everything? Corporations lobby for policies that save them money at the cost of our environment. Yes there are things individual people can do to help but posts like this one from CNN shift the focus from the actual problem
