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 ...
Source states: "This graph shows cumulative changes in sea level for the world’s oceans since 1880, based on a combination of long-term tide gauge measurements and recent satellite measurements. This figure shows average absolute sea level change, which refers to the height of the ocean surface, regardless of whether nearby land is rising or ...
Sea level rise lags behind changes in the Earth's temperature by decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. [20] What happens after that depends on future human greenhouse gas emissions. If there are very deep cuts in emissions, sea level rise would ...
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.
“The coastal hazard through 2050 is more likely driven by land subsidence than sea level rise, and this has to come across very clearly in every sea rise strategy,” he said.
A study published Monday finds sea level rise along the coast of the southeastern United States has accelerated rapidly since 2010, raising fears that tens of millions of Americans’ homes in ...
This results in global eustatic sea level rise (fall) because the Earth is not expanding. Two main drivers of sea level variation over geologic time are then changes in the volume of continental ice on the land, and the changes over time in ocean basin average depth (basin volume) depending on its average age.

He pointed out that 19 of the 25 cities most threatened by a 1m sea-level rise are in Asia, with seven in the Philippines alone. "Sea-level rise and flooding will have serious economic consequences.
