Sea ice melt is a huge worry because it changes the albedo of the polar ocean. That means more heating from the sun, which means a warmer Arctic and a warmer planet. It's one of the positive reinforcement mechanisms that's a huge worry to the climate community.
Greenland melting is also huge, and sea ice melting will make it go faster.
