Ocean Level Have Been Rising For Millennia, Slower Recently

This graph starts at the peak of the last ice age (Glacial Maximum) and shows sea level rise as the glaciers melted.  The rapid sea level rise slowed about 8,000 years ago, but continues.

Notice that the vertical scale is 10 meters (30 ft.) per division.

24,000 years of sea level rise

This graph starts at the start of the last ice age and shows that the rate of rise has slowed, but continues.

Notice that the vertical scale is 1 meter (3 ft.) per division.

8,000 years of sea level rise

The last 120 years show a constant rate of rise, with no noticeable speed up after the 1950s when CO2 levels increased.

Notice that the vertical scale is 0.05 meter (2 inch.) per division.

The rate of rise was 20 cm (8 in.) in the 100 years from 1910.

120 years of sea level rise

This IPCC chart shows a range of projections from various models along with “uncertainty” envelope.

The range of the upper projection is from about 0.1m (4”) to 0.9m (36”) inches.

The mid point of the various projections is about 0.44 m (17”)

This is a doubling of the recent historic rate of rise. Or an extra 9 inches on top of the historical 8 inches.

IPCC projects average 0.4 m

Notice that the IPCC prediction is about double the recent rate of rise and that Al Gore’s prediction is many times that of the IPCC.

Kinematic Constraints on Glacier Contributions to 21st-Century Sea-Level Rise

W. T. Pfeffer,1* J. T. Harper,2 S. O'Neel3, Science 5 September 2008: Vol. 321. no. 5894, pp. 1340 - 1343 DOI: 10.1126/science.1159099

On the basis of climate modeling and analogies with past conditions, the potential for multimeter increases in sea level by the end of the 21st century has been proposed. We consider glaciological conditions required for large sea-level rise to occur by 2100 and conclude that increases in excess of 2 meters are physically untenable. We find that a total sea-level rise of about 2 meters by 2100 could occur under physically possible glaciological conditions but only if all variables are quickly accelerated to extremely high limits. More plausible but still accelerated conditions lead to total sea-level rise by 2100 of about 0.8 meter. These roughly constrained scenarios provide a "most likely" starting point for refinements in sea-level forecasts that include ice flow dynamics

London Telegraph About a Sea Level Expert :

But if there is one scientist who knows more about sea levels than anyone else in the world it is the Swedish geologist and physicist Nils-Axel Mörner, formerly chairman of the INQUA International Commission on Sea Level Change. And the uncompromising verdict of Dr Mörner, who for 35 years has been using every known scientific method to study sea levels all over the globe, is that all this talk about the sea rising is nothing but a colossal scare story.

. . .

Despite fluctuations down as well as up, "the sea is not rising," he says. "It hasn't risen in 50 years." If there is any rise this century it will "not be more than 10cm (four inches), with an uncertainty of plus or minus 10cm". And quite apart from examining the hard evidence, he says, the elementary laws of physics (latent heat needed to melt ice) tell us that the apocalypse conjured up by

Al Gore and Co could not possibly come about.

. . .

When running the International Commission on Sea Level Change, he launched a special project on the Maldives, whose leaders have for 20 years been calling for vast sums of international aid to stave off disaster. Six times he and his expert team visited the islands, to confirm that the sea has not risen for half a century. Before announcing his findings, he offered to show the inhabitants a film explaining why they had nothing to worry about. The government refused to let it be shown.

. . .

When I spoke to Dr Mörner last week, he expressed his continuing dismay at how the IPCC has fed the scare on this crucial issue. When asked to act as an "expert reviewer" on the IPCC's last two reports, he was "astonished to find that not one of their 22 contributing authors on sea levels was a sea level specialist: not one". Yet the results of all this "deliberate ignorance" and reliance on rigged computer models have become the most powerful single driver of the entire warmist hysteria.
