Losing Louisiana

Sea-level rise, subsiding lands in the delta will claim 10 percent of state by 2100

Residents of Louisiana, take note: If engineers don’t divert sediment-rich waters from the Mississippi River to help replenish a sinking river delta, about 10 percent of your state will slip beneath the waves by the end of this century.
