Since the coast water is rising,it would be hard to find fresh water. The people would not be able to use the water,because it would be contaminated with bacteria. If all of the ice does melt,most of the fresh water will turn to salt water,and we would have to adapt to a new way of life. People would have to live on higher land,there would be no one to grow crops,and their would be no way that trees would survive,meaning we would not be able to breathe.The worst part of this all is that the Earth's temperature will sky rocket,and it will be so hot,the Earth will kinda be like a huge hurricane.(lol)
Hope this helped and good luck!
