Riven,
The conclusion made above are rather well-known fats - and conclusions - from the Scandinvian debate and research of the ice-age. The contribution reffered to are adding some valuable facts to this debate, -but some are still left out of due consideration...
One quote;
"Ocean levels rose at a rate of more than a metre per century around 10,000 BP, but the water level was still 30 metres below what it is today (Taipale & Saarnisto 1991: 237)". (endquote)

The estimates applied in the Scandinavian models does not take into accounting that a general rise of the oceanlevels are of the size of 120-160 metres, occuring at the end of ice-time, - all over the globe. Which includes the North Atlantic and the White Sea.

Nor does the geodynamic models of the rises of Scandinavia apply. The land-rise were MUCH faster than 1 cm a year, which is the level measured throughout the 50-ties and 60-ties. Today that rise is down to 0,30 cm a year, - clearly stating that the tectonical rise - after ice-time - is just about to end, - at a tectonical balance in the crust of the northern hemisphere. In the most northern west-coast of Finland - where the ice-cap had its core (optimum of 5 km+). Here the rise is still 1 cm a year -which is more than 3 times the speed of any other area of Scandinavia today.

Thus statistic data as this may be misinforming. According to the geodynamical models of Sweden/Norway the land-rise of the first millenium after ice-time (9.-10.000 BP) is about 150 metres, giving a midle value of 150 cm a year. Instead of 1.

Then there are some quite recent facts - from international geology - that doesnt really apply to the models made to explain the sudden disappearance of the ice-sheet and the artic climate.

Thus we get the explanation that the enormous mass of a 3000 metres thick glacier - larger than Fenno-Scandia, upported by a North-Atlantic glacier from the present Nort Pole covering land and oceans as far as South Greenland and Iceland - should have "melted away".
Which takes time.

The stratigrafical measures says that it all melted away between 11-18.000 years ago, covering the time from 1) Maximum extent, to 2)Minimum extent, as todays reality.
Thus the "Baltic bassin" are supposed to have collected all the melting water - as ice-cold fresh-water, inside an isolated bassin. Consequently we find the next argument - the sudden rise of climate in Scandinavia specifically, - as the reservoir of cold water are bursting, as out of a dam - to connect with the oceans.

Simultaniously our geologists get to strengthen their logic explaination to the sudden slide of "the remaining, regional and local glaciers" - as well as the sudden rise in the regional temperatures.
As all the stored coldwater rushed OUT of the Baltic Ocean.

But, - the studies are far from complete. Even if a sharp rise in the Global Temperature may occur - it is difficult to explain the "sudden shifts" described (above, too) as a mere change in the temperature of the global atmosphere. Heating away a 5000-3000 metres thick ice-CAP, by sun and wind alone? Fully possible, - but not in 6000 years.

We still have some fragments of the large ice-cap existing, as the artic ice, Greenland and some more glaciers. But none of them have melted much (more) - in the LAST 9.000 years.

/Before recently, - as the gulf-stream managed to gnaw it way through the Arctic Ice-cap and reach the North Pole. As the ice-sheet is now broken - even during winter - the Gulfstream is repported to have started whirling around it, before levveling out - to both the Atlantic and the Pacific./

The work refferd above keeps the main-line of the "old" explanation to the swift changes of the last ice-time and its "de-glacification". Thus it also overlooks present archological data - proving human populations to have existed in;

1) Varanger/Alta - Norway, 9.900 BP.
2) Kolan Pennisula, east coast, 13-17.000 years ago.
3) Moscow, 17.000 years ago
4. White Sea and Kara Ocean; 36-40.000 BP
5. SW Finland, 11.000 - 280.000 years ago.

(The recent habitat have been used continously - during all known interglacials - from the last 300.000 years, - including the last one...)

The processes of glaciation and de-glaciation is still far from clear. Present researh still work on a model of it`s largest (definite maximum) extent, as well as the consequences of the end of glacial America and Eurasia. A model of the (still) rising of continents, rising parts of continents and local varations along tectonic meltpoints - are just in the making.

Then we have to relate local, regional and tectonic differences - in the reaction to a vanishing pressure of 3-5000 kilometres thick ice - weighing some 0.91 kg pr cubic centi-litre.

As the tectonic reactionS are understood and measured - we have to relate the real rise of the arctic sea-levels, corrected and controlled by the present data from southern waters, stating a rise of 160 metres. And - mind us - the oceanographic surveys have just started to investigate this question in particular...
