Global warming and raised sea level?

Question

The main bulk of the earth's ice lies trapped in polar ice caps which are floating on sea water. If these floating ice caps melt due to global warming by how much will the level of the earth's oceans actually fall due only to the melting of this ice? If you now consider the ice from sea level up to 1000metres melting I suggest the melting of this ice would not produce enough water to pose the kind of threat you advertise.

Answer 1

Where did you get those facts.  Canada  and Alaska and Russia are not floating and there is ice atop of them.  Antartica is a solid land mass. with ice atop of it.  If it melts in the north, it is gonna melt in the south.  Did you figure that in your calculations.?

Answer 2

If the polar ice caps melt, the sea level will not fall but will rather rise.

Also, I have definitely not advertised anything about a possible threat of rising sea levels!

Answer 3

3/4 of the ice would evaporate into the air. A simple experiment can prove that....take 1 cup of water and freeze it...then let it melt...the water level would be lower than what was frozen.

Answer 4

If I fill a glass half full of coke, then finish filling the glass with ice, when the ice melts, how much slower will the coke/water level be, than if I hadn't added ice? Duh..........!!!!

Answer 5

Rise not fall..

If small glaciers and polar ice caps on the margins of Greenland and the Antarctic Peninsula melt, the projected rise in sea level will be around 0.5 m. Melting of the Greenland ice sheet would produce 7.2 m of sea-level rise, and melting of the Antarctic ice sheet would produce 61.1 m of sea level rise. The collapse of the grounded interior reservoir of the West Antarctic Ice Sheet would raise sea level by 5-6 m.

Edit:- As you can see from link below - Sea levels have in fact risen exponentially over the past 10 years and will keep doing so unless Global warming is addressed-

Answer 6

Floating ice melting will not change sea level at all. Ice on land that melts will raise sea level. Ice at the south pole is not floating.  The sea level WILL NOT DROP because some of the VOLUME of floating ice is HELD ABOVE THE LEVEL OF THE SEA. FLOATING ICE MELTING EQUALS NO LEVEL CHANGE.
