By the 2010s, Greenland was contributing roughly 0.8 mm/yr to sea level rise, and Antarctica was contributing roughly 0.4 mm/yr, both accelerating by 10%/yr (a doubling time of 7 years). [citation needed] Climate models estimate they will contribute 1 m - 2 m to sea level rise by 2100, mostly in the latter half of the century [10] [11]
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.
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.
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 ...
Sea levels are rising faster than previously anticipated—and it's only going to get worse. According to NASA, sea levels have risen an average of three inches in the past 23 years—with ...
Climate Central says global warming has caused global sea levels to rise 8 inches since 1880, and the rate is accelerating. The study projects that a 2-degree Celsius increase in temperatures ...
Deglaciation influences sea level because water previously held on land in solid form turns into liquid water and eventually drains into the ocean. The recent period of intense deglaciation has resulted in an average global sea level rise of 1.7 mm/year for the entire 20th century, and 3.2 mm/year over the past two decades, a very rapid increase.
It will take four feet of sea level rise to drown nearly half of Waikiki, and researchers plan on one foot of sea level rise by 2050 and four to six feet by 2100.
