South Louisiana is a thrill ride

Sometimes when I'm just sitting here, I like to throw my hands up and say, Wheeeeee! Try it. You can feel the drop a lot better that way.

Land along Louisiana's coastline is sinking 50 percent faster than was estimated just two years ago, according to a new map published Wednesday (June 14) as part of a study by Tulane University geologists. It says the average subsidence is 9 millimeters a year, more than one third of an inch.

That's subsidence alone, by the way.  Add in the sea level rise and you come to understand that you may get wet on this ride.
