Louisiana’s Governor Declares State Of Emergency Over Disappearing Coastline
The first two comments seem to associate anthropogenic climate change with the changes in Louisiana's coastline. A more likely culprit is hydrologic mismanagement. The coastline was formed by waterways that periodically changed channels and dumped sediment in different areas. In relatively recent times cities on the existing waterways became politically influential enough for the federal government to build a series of controls to prevent waterway changes that would otherwise distribute silt more evenly along the coastline.Given the long-running chronic nature of the coastline change, I'm surprised this is being raised as an "emergency." Given that the principal cities of government and commerce in Louisiana would likely be extremely negatively affected by an honest root cause analysis (without the Mississippian waters, they won't work so well as ports), I'd bet the powers that be will play up climate change and ask for lots of money to be pointlessly dumped in the gulf.
