Global sea level rose by a total of more than 120 metres as the vast ice sheets of the last Ice Age melted back. This melt-back lasted from about 19,000 to about 6,000 years ago, meaning that the average rate of sea-level rise was roughly 1 metre per century.
Previous studies of sea-level change at individual locations have suggested that the gradual rise may have been marked by abrupt 'jumps' of sea-level rise at rates that approached 5 metres per century. These estimates were based on analyses of the distribution of fossil corals around Barbados and coastal drowning along the Sunda Shelf, an extension of the continental shelf of East Asia...
"Rather than relying on individual sites that may not be representative, we have compared large amounts of data from many different sites, taking into account all potential sources of uncertainty," said Professor Eelco Rohling of the University of Southampton's School of Ocean and Earth Science...
Using an extensive series of sophisticated statistical tests, they then reconstructed sea-level history of the last 21 thousand years with a high degree of statistical confidence.
Their analyses indicate that the gradual rise at an average rate of 1 metre per century was interrupted by two periods with rates of rise up to 2.5 metres per century, between 15 and 13 thousand years ago, and between 11 and 9 thousand years ago.
The first of these jumps in the amount of ice-sheet meltwater entering the world ocean coincides with the beginning of a period of global climate warming called the Bølling-Allerød period. The second jump appears to have happened shortly after the end the 'big freeze' called the Younger Dryas that brought the Bølling-Allerød period to an abrupt end.

Let’s hope he lands directly on top of Michael Moore.
Better yet, the other way around.
Which means that most of the global water is now in the ocean. which further means oceans won’t rise, but can only recede in the next cooling period. New oceanfront property.
When you read the phrase “(may) happen, have occured, take/took place, be seen, could be seen, etc...... Stop reading! It’s not science.
B.S.
The next Mini-Ice Age has apparently arrived.
Coldest in central England since 1659
And if you do the math, that is 351 years.
It’s a good thing the Bølling-Allerød period happened long before humanity needed to know how to pronounce it correctly.
I would have been shocked if they found the level change had been gradual. Earth history doesn’t seem to involve much gradualism.
It happened about once a month for thousands of years, so, yeah, very lucky.
AND it was hyphenated.
:’) It would kill some people of whom I know to read that. :’)
