Ignorant, uninformed question: are insurance actuaries managing mortgages and properties following these updates? What is going to happen to families with land in areas that are going to be permanantly flooded in 10, 20, 30 years? Do we even have a plan for that?
Interesting bit: during a press event recently, Warren Buffett was asked whether increasing climate-related catastrophes would hurt the insurance companies in his portfolio. The answer was, to paraphrase, that they would help the companies more than hurt them. Even in a particular year that has unforeseen high levels of disaster, the companies will quickly update their risk models and increase their premiums, essentially bringing in the same margins as before on a larger risk pool = more profit.
