I am not sure if you are aware, but water will expand roughly 8% when frozen. This is another way of saying that the area water takes up will decrease by roughly 8% when it melts (when it is no longer frozen).
It's actually closer to 9%. Regardless, sea levels will rise because the majority of the ice is not currently in the sea, but above it. When it all melts, sea levels will rise by around 70 meters.

Unfortunately, anyone who even questions the conclusion of global warming is shouted down, so there is little to no debate within the scientific community on the matter.
I have done zero shouting down. I'm the one providing evidence and facts for my position. You're the one refusing to read or respond to them. If anyone is ignoring the other side here, it's you.
