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 ...

"During droughts, rising sea level could make fresh water less available—particularly groundwater, which provides 80 percent of Guam's water supply. Most of Guam's fresh water comes from the northern part of the island, which has a "lens" of fresh groundwater floating on top of the heavier, saltier water.
Geologic map of Guam. The geology of Guam formed as a result of mafic, felsic and intermediate composition volcanic rocks erupting below the ocean, building up the base of the island in the Eocene, between 33.9 and 56 million years ago. The island emerged above the water in the Eocene, although the volcanic crater collapsed.
Map of the Earth with a long-term 6-metre (20 ft) sea level rise represented in red (uniform distribution, actual sea level rise will vary regionally and local adaptation measures will also have an effect on local sea levels). After 500 years, sea level rise from thermal expansion alone may have reached only half of its eventual level - likely ...
Comparison of two sea level reconstructions during the last 500 Myr: Exxon curve and Hallam curve. The scale of change during the last glacial/interglacial transition is indicated with a black bar. The sea-level curve (also known as the eustatic curve) is the representation of the changes of the sea level relative to present day mean sea level ...
