From the WashPost: The Drowning South; The new face of flooding. An excerpt:

Human-caused climate change is driving an acceleration of sea level rise globally, largely because of the faster melting of the globe’s giant sheets of ice. Scientists do not know for certain why this region is experiencing a surge in sea levels beyond the global average, but one theory is that naturally occurring ocean currents are moving ever-warmer ocean water deep into the Gulf. This warm water expands and causes seas to rise. This comes on top of sinking land, which has long exacerbated sea level rise in the region.
