In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
The opposite of transgression is regression where the sea level falls relative to the land and exposes the former sea bottom. During the Pleistocene Ice Age , so much water was removed from the oceans and stored on land as year-round glaciers that the ocean regressed 120 m, exposing the Bering land bridge between Alaska and Asia.
Ninety percent of the Mediterranean Basin flooding occurred abruptly during a period estimated to have been between several months and two years, following low water discharges that could have lasted for several thousand years. [3] Sea level rise in the basin may have reached rates at times greater than 10 metres per day (33 ft/d).
Sea level rise of 0.2–0.3 meters is likely by 2050. In these conditions what is currently a 100-year flood would occur every year in the New Zealand cities of Wellington and Christchurch. With 0.5 m sea level rise, a current 100-year flood in Australia would occur several times a year.
[16]: 1216 This was faster than the sea level had ever risen over at least the past 3,000 years. [ 16 ] : 1216 The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. [ 17 ] Climate change due to human activities is the main cause.
A WMO spokesperson said that the impact of rising water levels on Pacific islands was disproportionately high since their average elevation is just a meter or two (3.3 to 6.5 feet) above sea level.
Most people know about sea-level rise as a result of warming oceans and melting glaciers, but not many are aware of the fact that geological changes as a result of the last ice age are also ...
The sea-level equation (SLE) is a linear integral equation that describes the sea-level variations associated with the PGR. The basic idea of the SLE dates back to 1888, when Woodward published his pioneering work on the form and position of mean sea level , [ 45 ] and only later has been refined by Platzman [ 46 ] and Farrell [ 47 ] in the ...
