344 309 966 tonnes of water will need to be displaced to make a one metre rise in the oceans of the world.
NO.
You would need to displace 361,000,000,000,000 Metric Tons to raise the oceans water level by 1 meter.
Current bulk shipping fleets of the entire world = 282,361,250 metric tons.
It's not even a drop in the bucket.
As an addendum to my post, I will elaborate on the math portion for you, so that you can follow along.
The Earths oceans have a total surface area of 361 million km squared or 361,000,000,000,000 meters squared
(361 trillion square meters)
Sea water has a density of 1000kg / m^3
SO, the first meter in depth of the ocean has a mass of 361,000,000,000,000,000 kg, which is the mass you would need to displace the ocean water level
by one meter.
Your Average Supramax Freighter = 50,000 DWT (Deadweight Tons) or (45,359,237kg)
(That's 45,359 metric tons.... 1,000kg = 1 metric ton.)
There are over over 6,225 Shipping vessels over 10,000 DWT in the world.
So, the current bulk shipping fleet of the ENTIRE WORLD displaces around 0.00000078216413 meters.
(782 nanometers) or, the width of a single bacteria cell.
