1. Almost all the Arctic ice is floating on the sea, according to Archimedes , the sea ice melting or freezing does not change the sea surface height, because ice and water are belong to the same material, the weight of dissolved water and the original ice are the same. If you put ice into a glass of water, when melting, the water level will not change.
2. The ocean thermal expansion caused by global warming is one of the main reasons of sea level rise.It is such as the theory of thermal expansion and contraction. Of course, the sea level will change in the different season.
