sea level rise stuff?

So... when there's a lot of ice, the sea level is lower than when there's just a little ice, right? I just need to be sure for an essay.

Update:

But ice floats on water so that doesn't effect the sea level right, does it?

    Today's ice floating on the sea doesn't alter the sea level. Archimedes principle says that ice or any matter floating on water, displaces (or occupies) the same volume that it would do after melting.

    Problem is - all that ice (snow) stacked on 5.5 millions miles² on Antarctica (bigger than Europe) to an average height of a mile & about 2 million miles² on the Arctic fringe-lands (0.8 million miles² on Greenland alone). If it melts & slips or flows into the global Ocean (all Oceans, Seas are connected) it would mean a rise of anywhere between 10 m (=33') to 67 m (=200'), with different experts giving different figures.

    Ice at the south pole is 'mostly' covering land, the continent of Antarctica. If all of this ice were to melt, ot would cause a rise in sea level.

    However, ice at the north pole is floating on water, since there is no continent at the north pole. If all of this ice were to melt, there would be no rise in sea level, since the 'former ice' in this location was already part of the ocean.

    I hope this is helpful.

    yes, the polar ice caps are melting and raising the sea level

    extremely we are in a position to make vast frig and shop the international interior it, each and every of the water interior the see will become ice the water point will flow down o down. After that the earth could nicely be taken out and the refrigerator could nicely be stored aside for next use or the different international who've comparable situation can use it they'll supply us funds for utilising it.
