Reassessment of the Potential Sea-Level Rise from a Collapse of the West Antarctic Ice Sheet
Open accessAbstract
Collapse and Rise: The West Antarctic Ice Sheet (WAIS) is thought to be inherently unstable and susceptible to rapid collapse if it reaches a certain warming threshold. Although such an event is considered unlikely, to predict the consequences of collapse it is important to know how much sea level would rise in such a case. The WAIS is thought to contain enough ice to raise sea level by 5 to 7 meters were it to collapse. Bamber et al. (p. 901 , see the cover; see the Perspective by Ivins ) have reassessed that number, on the basis of better data on the geometry of the WAIS, and conclude that its sudden collapse would raise sea level by about 3.2 meters, on average, with large and important regional variations. Although this is only about half as much as previously thought, its impact on coastal areas would still be devastating.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
