Earth volume = 1,083,206,917,000 cubic km

- The radius of the Earth is an average of 6371km (volumetric mean)

- Assuming an average depth of 3.79km the volume of ocean seas will be:

1,085,141,211,000 cubic km

- The volume of water will be the difference between these two quantities:

1,934,294,000 cubic km

- The proportion of water to land is roughly 71:29, so the actual volume of water will equate to:

1,373,348,740 cubic km

- The diameter of a comet (water source) necessary to deliver this quantity of water would need to be about

The baseline water temperature and the associated volume of the oceans cannot be known. It is possible that the maximum atmospheric temperature has not yet been reached where cooling by the melting ice will result in much of the global land is threatened with deepening waters. This is now speculated, but scaremongering for cynical (or other) reasons is unforgivable. Science

Alternatively, the minimum is still to be achieved. The melting-ice volume in the Antarctic has yet a long way to go before it is exhausted. The current problem is that increased water levels are just inconvenient. Living in low lands is not the best place to be, but Earth's climate cannot just be massaged to make it convenient.
