I share your concern over the risks posed by the loss of sea ice. However, per the Thwaites Glacier Collaboration, even if the entire glacier were to collapse it would amount to around a 65cm rise of sea level, and the majority of that would come in the 22nd and 23rd century.

Ok, cool. idk. Was just referencing stuff like this, from Wired: "If it totally melts, the Thwaites Glacier, aka the Doomsday Glacier, could add 10 feet to sea levels. Sea ice protects Thwaites and other glaciers because it acts like a buffer, absorbing the energy of winds and waves that would otherwise erode them."
