"an unusually broad and vast Antarctic glacier" "closely monitored for its potential to elevate sea levels. ...described as part of the "weak underbelly" of the West Antarctic Ice Sheet, in part because they seem vulnerable to irreversible retreat and collapse even under relatively little warming, yet also because if they go, the entire ice sheet is likely to eventually follow." "The amount of ice from Thwaites likely to be lost in this century will only amount to several centimetres of sea level rise, but its breakdown will rapidly accelerate in the 22nd and 23rd centuries, and the volume of ice contained in the entire glacier can ultimately contribute 65 cm to global sea level rise" https://en.wikipedia.org/wiki/Thwaites_Glacier https://en.wikipedia.org/wiki/Thwaites_Glacier
