Duplicated question. Do you mean tons or tonnes?

probably as much as ten years ago until you read bent reports from the government.

it's 2.85 million km³ as a cubic metre is about a tonne and there's a trillion cubic metres in a cubic km that's in excess of 3 million trillion tonnes.

Can you be a bit more precise jake

[jake-the-peg]

Not without spending longer researching it - a few minutes only gave me the volume - the ice is very thick so will be denser at the bottom so that figure's going to be a minimum.

I'm sure you can get a better figure gromit

A gallon of water weights about 10lbs. You can do the calculation yourself.
