While trend-line warnings certainly have their place, we might be interested in the idea that the price of peanuts might go up for instance, they usually fall apart because they don't account for a reaction to a changing situation.

Florida Keys Prepare For Sea Level Rise
Associated Press, 2 July 2013 (hat tip: NC)
A tidal gauge operating since before the Civil War has documented a sea level rise of 9 inches in the last century, and officials expect that to double over the next 50 years. So when building a new Stock Island fire station, county authorities went ahead added a foot and a half over federal flood planning directives that the ground floor be built up 9 feet.
Seasonal tidal flooding that was once a rare inconvenience is now so predictable that some businesses at the end of Key West's famed Duval Street stock sandbags just inside their front doors, ready anytime.
Note that this does not make the keys hurricane, or flood proof, but they do argue against them becoming immediately uninhabitable."It's really easy to see during our spring high tides that the sea level is coming up — for whatever reason — and we have to accommodate for that," said Johnnie Yongue, the on-site technician at the fire station for Monroe County's project management department.
