For mid-latitude coasts that border subduction zones, sequences of buried soils may provide a long - duration, subsidence stratigraphic paleoseismic record that spans to the present, but in other settings such as the Aceh coastal plain, joint research approaches, for example targeted foraminiferal analyses and palynology, are required to both exploit the changing form of the relative sea - level curve and characterize coastal evolution in the context of the diminishing importance of accommodation space.

The papers questioned everything from the relative role of natural mechanisms in changes to the climate system vis - à - vis increased CO2 concentrations, the allegedly «unprecedented» nature of modern climate phenomena such as warming, sea levels, glacier and sea ice retreat, and the efficacy and reliability of computer climate models for projecting future climate states.

Not only that, but since the 1980s, more land area is above water than below it, indicating that tectonics and subsidence / uplift have much more to do with long - term relative sea level than climate or changes in water temperatures do.

But, tidal gauges are located on land, so if the land (where the gauge is located) moves up or down over time, this would cause an apparent change in the relative sea level, without the sea level actually changing.

The exchange of water between the land, ocean and atmosphere is an essential factor driving changes in ocean mass and relative sea level, both of which are important indicators of climate change.

Such changes in mass and relative sea level can be affected by the physics of self - attraction and loading (SAL).

Sea level changes can be driven by either variations in the masses or volume of the oceans («eustatic»), or by changes of the sea surface relative to the land («relative»Sea level changes can be driven by either variations in the masses or volume of the oceans («eustatic»), or by changes of the sea surface relative to the land («relative»sea surface relative to the land («relative»).

An understanding of sea - level change requires maintaining a clear distinction between global (or eustatic) sea - level and local relative sea - level.

Thermal expansion of seawater and melting continental ice sheets relevant to global warming are tiny effects relative to secular sea level change of ancient times.

The present sea level rise now observed is very small relative to sea level changes on geological time scales.

The paper by Tamisiea et al. (2010) examines how the exchange of water between the atmosphere, oceans, and continents can contribute to the water cycle, load the Earth and change its geoid, and cause the annual variations in relative sea level over the global ocean.

Coastal management must instead rest upon accurate knowledge of local geological, meteorological and oceanographical conditions, including, amongst other things, changes in local relative sea level.

Coastal stability in polar regions is affected by factors common to all areas (exposure, relative sea - level change, climate and lithology), and by factors specific to the high latitudes (low temperatures, ground ice and sea ice).

In the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Bindoff et al. (2007) projected a mean global sea level rise somewhere in the range of 18 - 59 cm relative to mean global sea level in 1990.

Rohling et al. [52] estimate an average rate of Eemian sea - level change of 1.4 m per century, and several studies noted above suggest that the Eemian sea level reached heights of +4 — 6 m or more relative to today.

If the sea level response to a change in temperature is an exponential decay to equilibrium then given that the 0.8 C temperature increase since pre-industrial times occurred over a relatively short time period relative to time scale of the ice - albedo feedback, the expected rate of sea level rise should be approximately 3 m / C * 0.8 C / 560 y = 43 cm per century.
