Other countries experience this effect as well; in a portion of Alaska and Canada, the relative sea level is falling by up to 2.0 cm (0.8 in) a year. In Norway, Sweden and Finland, an effect called Fennoscandian land elevation causes the relative sea level to fall by up to 0.7 cm (0.3 in) a year. [5] [6]
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.
At the height of the last ice age, around 18,000 years ago, the global sea level was 120 to 130 m (390-425 ft) lower than today. A cold spell around 6 million years ago was linked to an advance in glaciation, a marine regression, and the start of the Messinian salinity crisis in the Mediterranean basin.
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 ...
The upcoming climate talks in Paris have generated a lot of buzz lately. Multiple large organizations are coming out with reports on the climate's future impact on humans, and the general ...
Rather than a sudden decline in sea level, intermittent periods of ocean-bottom hyperoxia and anoxia (high-oxygen and low- or zero-oxygen conditions) may have caused the 13 C ⁄ 12 C ratio fluctuations in the Early Triassic; [108] and global anoxia may have been responsible for the end-Permian blip. The continents of the end-Permian and early ...
Sea levels are rising fast, and predicted to climb higher in the coming decades. This makes buying a retirement home that's right on the water a risky move. 5 beach retirement spots to escape ...
