WebOn short time scales, sea level changes globally and locally because of the tide and the effect of storm surges. On longer time scales, sea level is affected by global climate change (ocean temperatures and the amount of land-based ice) and the vertical movement of land masses relative to the sea due to the Earth’s crust rebounding following the last ice age.

Webaverage, and changes in local relative sea-level (LRSL), which correspond to changes in actual sea-levels at real and particular coastal locations. In general, statements made by the IPCC, CSIRO and government planning and management authorities, which use the unqualified and ambiguous term “sea level”, are referring to eustatic sea level. WebGeophysical models propose that a former path of ice retreat can be divided into sea-level zones based on the thickness of ice over the region. The predicted position of these zones fits remarkably closely to the observed positions. Fifteen different, detailed curves of relative sea level have been obtained in the Atlantic Canadian area and three composite curves …

WebRelative sea level change is how the height of the ocean rises or falls relative to the land at a particular location.
