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 ...
Image showing sea level change during the end of the last glacial period. Meltwater pulse 1A is indicated. Meltwater pulse 1A (MWP1a) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of rapid post-glacial sea level rise, between 13,500 and 14,700 years ago, during which the global sea level rose between 16 meters (52 ft) and 25 meters (82 ft) in ...
Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B (MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 years ago at the beginning of the Holocene and after the end of the Younger Dryas.

CLIMAP has been a cornerstone of paleoclimate research and remains the most used sea surface temperature reconstruction of the global ocean during the last glacial maximum (Yin and Battisti 2001), but it has also been persistently controversial. CLIMAP resulted in estimates of global cooling of only 3.0 ± 0.6 °C relative to the modern day ...
To form the ice sheets of the last Ice Age, water from the oceans evaporated, condensed as snow and was deposited as ice in high latitudes. Thus global sea level fell during glaciation. The ice sheets at the last glacial maximum were so massive that global sea level fell by about 120 metres. Thus continental shelves were exposed and many ...
The early Holocene sea level rise (EHSLR), which began c. 10,000 BC, tailed off during the 6th millennium BC. Global water levels had risen by about 60 metres due to deglaciation of ice masses since the end of the Last Ice Age. [22] Accelerated rises in sea level rise, called meltwater pulses, occurred three times during the EHSLR.
Their simulation had run for over 1,700 years before the collapse occurred and they had also eventually reached meltwater levels equivalent to a sea level rise of 6 cm (2.4 in) per year, [39] about 20 times larger than the 2.9 mm (0.11 in)/year sea level rise between 1993 and 2017, [79] and well above any level considered plausible.
The sea-level data from the Rhine–Meuse Delta indicate a 2–4 m (6 ft 7 in – 13 ft 1 in) of near-instantaneous rise at 8.54 to 8.2 ka, in addition to 'normal' post-glacial sea-level rise. [26] Meltwater pulse sea-level rise was experienced fully at a great distance from the release area. Gravity and rebound effects associated with the ...
