I think that Antarctica would fall apart because It Is

Mostly just ice. A lot of the North Pole would collapse. 

Polar bears would die, and penguins a lot of animals would go extinct some of the ice burgs here would collapse. In Peru there is a lot of ice burgs that would melt. Some people will die from the causes of iceburgs. In parts like Ireland and Russia Czech Republic Serbia England Norway Finland and Sweden would totally melt.

And new Zeeland Australia would melt. And that’s what would happen if all the ice melted. I hope you learned.
