Simon asked:

How much would the level of the oceans rise if we emptied every car heating system, swimming pool, drinks container etcetera and all the places where we store liquids globally?


Assuming everyone was storing maybe a cubic metre of water, (although some people have very big swimming pools most people maybe only have a little tank of water in the loft between four or five people). So with ten billion people wed have 10,000 billion litres of water stored. If you work out the area of the Earth it comes out at about 100,000 billion square metres so maybe sea level would rise by about a millimetre.

The calculation is that every twenty thousand years or so enough water arrives from outer space to raise the level of the oceans about an inch. So, its miniscule against that.
