So far a large portion of the ice melting is sea ice. Because that was already floating and thus displacing water it doesn't actually impact sea level. That's why people always talk about Greenland and Antarctica, two landmasses with huge amounts of ice on them (often kilometers deep). When their ice melts (and it is melting, just slower) you see notable changes in sea levels. This will also accelerate when there's less sea ice around the land keeping things cool
