Coastal Cities Face $1 Trillion Floods by 2050

2. If you have friends or family living in coastal flood plains/waterfront properties

Ask them to consider this. Can they afford to take a total loss on their property? Can they afford an increase in flood plain insurance to $15,000-20,000 a year? If not, urge them to sell their property while there are still climate change deniers out there foolish enough to purchase in a flood plain (and that window of opportunity is shrinking with every news story/report like the OP's link). Then either move somewhere on higher ground, OR if they are determined to remain in their present location, rent or short term lease a property. And keep in mind that landlords may opt out of flood plain insurance, and it may be prohibitively expensive to get renter's insurance, so a second or third floor apartment would be the best bet.
