Sea level rise is a physical phenomenon, does not happen in a monotonic fashion. Difficult to explain the full significance of each mm rise to morons.
But, weeds, vermin, etc are biological phenomena, given to exponential growth rates and can flip things around suddenly
You see forsythia blooming in April first week in your area? It used to bloom in late April usually, does it mean anything? That crocus is blooming in Jan?
So much of the weeds, vermin like stink bugs get killed by hard frost over the winte
Please educate us: how is the sea level at Shanghai higher than everywhere else?
The ocean is not a static body of homogenous fluid, but rather a dynamic system of intermixing (but not perfectly mixed) different fluids. Both different densities (e.g. less saline or warmer water in some regions) and changing currents can lead to differences in sea level and differences in sea level rise.
Mean *local* sea level does in fact vary from place to place due to many factors, starting with the fact that the Earth is not a geometrically perfect sphere. On top of that you have local gravity differences due to variations in the thickness of the Earth's crust, as well as large scale ocean circulation patterns and differences in ocean water density -- both from temperature and salinity.
So yes, local mean sea level in Shanghai *can* be higher than the global mean sea level, which in turn can be higher
In 2022, China's coastal sea levels were 94 millimeters (3.7 inch) higher than "normal,"
Noooo! 3.7 inches! Whatever will we do? Run for your lives?
4.0 mm per year since 1993. That's right in the error band of the predictions published in the IPCC first assessment report (1995), which said 3 to 10 cm of sea level rise per decade in the 21st century for the "business as usual" scenario

Those that do not understand what they are talking about will forever voice stupid opinions...
