Phoenix sinking 1mm a year is so negligible until California splits off. Our worst issue is floods from torrential downpours, not the ocean

    Maybe I’m an idiot but how does “mm per year” classify you as being at a high risk of sinking? Seems a lot different depending on your elevation. The highest peak could sink a meter per year and still not be at risk of flooding

    True, for not being at risk from flooding from the ocean given elevation (from sea level).

    Local flooding: entirely possible. For example, over a few years city X sinks by a cm, because of that in a flood situation there's slightly more flood water. Over a large area that might be quality a few acre-feet of water: that's quite a lot more water.

    It's less that the likely hood of a flood increases and more that the severity of a flood increases.

    LOL @ Seattle....

    yeah, bits will be underwater one day. thank goodness most of the town is up on giant ridge lines and hills.

    I suspect the Houston number is actually Katy or the gre at Houston area as a whole because last I check Houston-proper has taken some action to reduce the pumping of ground water and mostly stabilized? But the surrounding suburbs think not wanting flooding is commi BS probably.

    the circle is the city location, not the tip of the cone, for anyone else who was confused

    Seattle was built by digging through the local hills and dumping them into the bay. Half the downtown wouldn't exist without these massive earthworks done a century ago.

    Still plently of hills left to start backfilling if needed.

    Seriously. i don't get the methodology here. Sea levels could increase ten feet and Seattle would lose like 5 city blocks. The AVERAGE elevation of Seattle is 180ft above sea level.

    Might just be because I'm not rich enough, but who has a 5cm thick credit card?

    Isn't New Orleans already sinking?

    Credit Cards have three dimensions, one of which doesn't seem to bad, so I am sure that is the one policy makers will choose to believe this chart is referencing.
