Sea-level Rise by 2100 Could Exceed IPCC Projections Under High Emissions Scenarios

One Earth, December 18, 2020
In relation to the above work on Antarctic sea-level rise, this late 2020 paper by several past and present IPCC authors may be of interest.  It addresses concerns that many current ice sheet models and data sets may well underestimate projections of sea-level rise from the Greenland and Antarctic ice sheets, especially under high emissions scenarios, inadvertently skewing the results towards the low end of possible projections.  The authors argue that outcomes above this range are far more probable than those below; and discuss how decision makers might benefit from a reframing of IPCC terminology, to avoid unintentional masking of worst-case scenarios.
