The fact that you talk about ice extension as anything relevant proves your lack of knowledge in this topic.

Ice extent is fairly irrelevant for sea level rise. Existing glacier melt for glaciers that are extremely large (kilometers deep) is extremely relevant for global sea level. The nelti of Antarctic glaciers has a very substantial impact on sea level and oceanic currents, which affects climate across the entire Southern hemisphere.
