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
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.
