The slope on the graph suggests that in the past 27 million years, the total quantity of water on Earth has increased from 1.0  to 1.2 trillion-trillion litres.

This  (0.2 x 10^24) divided by 27 x 10 ^ 6

This is equivalent to 0.074074  x 10 ^ 18, litres per year

Or  7407.4 trillion litres per year

Water accumulation calculated from Sea Level rise over past 100 years

The surface area of the oceans on Earth has been estimated at 361 million kilometres square. The ocean level has increased 18 cm in the past 100 years.

The increase in volume of ocean by the rise over the past 100 years is therefore

361,000,000 x 0.00018  cubic km

equals       64980 km 3 over 100 years

equals        649.8 km 3 over 1 year

equals       649.8 x 10 ^ 12   litres/ year

Or          649.8 trillion litres per year    (about 650 km3)

This amounts to    17544.6 x  10 ^ 18  litres/ year  over 27 million years

Or     0.0175 trillion-trillion litres

The Earth, according to my models has increased its radius by 5% in the last 27 million years and so the surface area of the Earth has increased too (mainly in the form of new ocean beds) and this will have negated sea level rise.

SEA LEVEL RISE INDICATORS

The North Sea Shelf

From the following image (adapted from Smith and Sandwell 1997) which indicates the bathymetry of the North Sea Shelf it confirms that mankind will have been able to walk across to England from Denmark, Germany or Holland until about 27,000 years ago. This is calculated by dividing the depth of the Sea (50 metres by the 18cm/100 year figure. Fossil trees have been recovered from the North Sea Shelf which confirm this.

THE ACCUMULATION
OF WATER

Volume of water produced in last 2000 years (Roman times) =

650 kms x 2000 = 1.3 million km3

Amount of ice on Greenland, according to Wikipedia is 1.747 million km3.

So if the sea level rise during this period was due to the melting of ice - the ice on a landmass nearly the size of Greenland would have had to disappear.
