But so is lower Manhattan, Miami, 60% of the land in the Netherlands, almost all of Bangladesh, along with numerous other places.
Now 3m-7m is vastly higher than any current predictions, but hey lets scare monger about a single city!
From page 1 of the paper: "Coastal Louisiana has been referred to as 'canary in the coal mine' with respect to climate impacts. As highlighted in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), the central US Gulf Coast is the single most exposed LECZ (low-elevation coastal zone) in the world in terms of projected relative sea-level (RSL) rise throughout this century."
> Notably it does not predict this
Again from page 1 of the paper: "The initial impetus consists of new evidence that RSL in this region is probably committed to 3-7m of future rise, with a shoreline bound to migrate as much as 100km inland. We argue that future RSL rise to this elevation – judging from field evidence rather than climate model output – is, in fact, a best-case scenario."
The 3-7m! Relocate now! stuff seems unfounded and irresponsible.
