Thwaites Glacier Study 2026: What the 3 cm Sea-Level Estimate Means
KEYWORD_WORLD · News · Checked 23 October 2026 (KST) A new Thwaites Glacier study puts its contribution to global average sea level at about 3 cm by 2100 in one model setup—roughly twice a comparison estimate. This is one glacier’s projected contribution under stated conditions. It is not a forecast of total sea-level rise or the water depth outside a particular home. The useful question is what changed in the model, and what that number can tell a coastal reader. Start with the ice, then check the units, assumptions and location.

Researchers at JPL, the University of California, Irvine, and Dartmouth studied how to represent the edge where land-supported ice starts to float. A grounding line is that boundary. A grounding zone is a wider tran...
