Cool article about 2 new papers, one a literature review and one a paleo view

Good German article https://www.derstandard.at/story/3000000319484/new-orleans-muss-in-absehbarer-zeit-wohl-umgesiedelt-werden
But in sea level articles I always miss why this should be a problem and be addressed today. 30cm for New Orleans by 2100 doesn't sound much. What are the actual impacts? A flooded basement at king tide? So what? I don't get it.
In IPCC AR6-WG2 one learns that #by2030, Bangladesh has to relocated 2/3 of her Southern fossil power plants due to sea level rise. You read that right: by 2030.
So there's one hint why 30cm can be a real problem: corrosion via saltwater intruding from below. and from the surface inflow.
Another is soil: saltwater renders agricultural land unusable, 1 flood event is enough. Dunno why this is so.
And there's another factor: if you think in 3D, imagine that all the coastal ocean area gets the added power of 30cm more water forcing its way inland during tides? And during storms!? When the waves crash against beaches or dams, and with this much more force from the tons and tons of more water… WHAM!
