Melting ice of the sea

Well, idiot, the premise of this stupid movie is all poles melting have flooded the entire planet. There are two poles. The south pole is mainly a continet COVERED with ice. The north pole is ice actually floating in the ocean. Just like any other iceberg. If this specific ice would completly melt, the sea level wouldn't rise one inch.

If you put a full glass of water filled with icecubes into the sun and wait for the ice to melt, the water won't spill. Its Archimedes' principle at work.
The myth off sea levels rising due to melting ice in the oceans has been refuted numerous times.
To be fair, some climate change apologist have since moved their tent-poles to other stuff like glaciers and carbondioxid.

Im too lazy to write all this stuff.
Here's the quote with the relevant info
"Sea ice melt contributes very slightly to global sea level rise. If the melt water from ice floating in the sea was exactly the same as sea water then, according to Archimedes' principle, no rise would occur. However melted sea ice contains less dissolved salt than sea water and is therefore less dense: in other words although the melted sea ice weighs the same as the sea water it was displacing when it was ice, its volume is still slightly greater. If all floating ice shelves and icebergs were to melt sea level would only rise by about 4 cm (1.6 in)"

All the catastrophic predictions of ocean rise are predicated on the notion of land ice melting. Sea ice is pretty much the same as ice cubes in a drink - not quite, but close. If all sea ice melts it will only have a few percent of the effect that the land ice. Land ice sheets and glaciers - That's where the hundreds of feet of maximum rise come from.
