Louis insisted on motion too, with one crucial difference: in his works, it's the colors themselves that are set in motion, especially so here, where no matter what distance you choose to view the work
from there is a sparkle of gentle
subsidence.
This means that, e.g., if heat moves
from the tropical surface water (temp about 25C) to surface waters at lower temps, the net effect is a
subsidence of sea level — even without any change in total heat content.
«Data
from GPS measurements and carbon dating of marsh sediments indicate that regional land
subsidence in response to glacial isostatic adjustment in the southern Chesapeake Bay region may have a current rate of about 1 mm / yr (Engelhart and others, 2009; Engelhart and Horton, 2012).
But the troposphere can still warm with an increased radiative cooling term because it is also balanced by heating through latent heat release,
subsidence, solar absorption, increased IR flux
from the surface, etc..

Venice's major problem is
subsidence, some of it due to pumping of water
from underground aquifers, some of it due to development, and some of it «natural.»
In New Orleans, geophysical vulnerability is characterized by its below - sea level, bowl - shaped location, its accelerating
subsidence, rising sea level, storm surges, and possible increased frequency of larger hurricanes
from climate change.
Vertical land movements such as resulting
from glacial isostatic adjustment (GIA), tectonics,
subsidence and sedimentation influence local sea level measurements but do not alter ocean water volume; nonetheless, they affect global mean sea level through their alteration of the shape and hence the volume of the ocean basins containing the water.
The problem will be compounded in many river deltas (Ganges, Mississippi, Nile, etc.) by a half meter or so of

Detailed impacts, however, will vary strongly
from region to region and coast to coast and therefore can not be easily generalized, as changing mean and extreme coastal water levels depend on a combination of near shore and offshore processes, related to climatic but also non-climatic anthropogenic factors, such as natural land movement arising
from tectonics, volcanism or compaction; land
subsidence due to anthropogenic extraction of underground resources; and changes in coastal morphology resulting
from sediment transport induced by natural and / or anthropogenic factors.
