# How much of Earth's surface would be covered by water if all ice melted? [duplicate]

I'm trying to find how much water would be on the surface of Earth and how much surface would it cover (how much land will remain) if all the ice at the North and South Poles (and everywhere else) would melt.

Please provide the source of the information.

• Based on water.usgs.gov/edu/graphics/earthwheredistribution.gif we can see that about 20.6% of the Earth's water is in icecaps and glaciers. It's unclear how the change from ice to water will affect sea level and also what amount of that 20.6% is ice already in the ocean (displacing sea and changing its level) and what of it is on land (not displaying sea level yet). Figuring out those variables would make it easier to estimate the change is sea level, which could then be used to answer your question of how much land would remain. I don't have that answer yet though. – cr0 Jan 11 '16 at 18:54
• If this graph are correct and I'm understanding it right, then 3% is ALL the fresh water... including in the ice... what makes no sense. And I think I understand this graphic picture correct, because above two columns it says 0.9% and 2% what is telling us it is from the 3% of total fresh water. But again, not making any sense to me... however, if it is, then it is about 0.65% of fresh water is in the ice, right? then what the hell... I mean it seems like more than this – theagouf Jan 11 '16 at 19:02
• Googling for your exact title question seems to give you partial answers. Don't let us do all the work. – Jan Doggen Jan 11 '16 at 19:49
• OMG! Jan! I'm sorry, I googled with other requests but didn't find the answer... googled it now with my own question and found what I was looking for :D I didn't mean you do search something I can do :) – theagouf Jan 11 '16 at 20:05
• @theagouf If you've found a good answer elsewhere, you are welcome to post it here as an answer to your own question :-). – Pont Jan 12 '16 at 8:29
