Why Is Sea Level Rise Worse in Some Places?

There are other factors, too. I remember reading about sea level change as a result of Greenland's ice melting. The sea level around Greenland is actually predicted to go down. One reason is that the ice is pushing the land down, and that effect will reverse as the ice melts. The other surprising reason is that the ice is massive enough to have a noticeable gravitational effect on the surrounding water.

Fun random factoid, big parts of Europe are still slowly rising because the weight of ice compressed a lot of it.

On the other side, a lot of land is sinking because the soil is drying out due to years of droughts and water mismanagement (farmers like to keep the water table lower. I live in NL where we have the water management infrastructure to tweak the water table)

Shockingly fast, too, in some spots.

"Over the past 14 years, the town has sunk as much as 11.5 feet in some places..."

Same thing happened in Vermont with some of the evidence for it being whale skeletons found in fields hundreds of miles from the ocean: https://en.wikipedia.org/wiki/Charlotte_whale

When the soil is drying out, it will start to float. Im from Boskoop in NL, we have that problem with peat soil (veen grond). This is also irreversible, when peat soil gets dried it will not become wet again.

Seems we are missing "Land level rise" and "Land level fall". Those will be more patchy and local than sea level.

That's exactly what TFA is explaining.

This is literally two of the three things the article talks about.

Yeah, and that's good locally, but globally we see a rise overall.
