Sea level could rise higher than current estimates by 2100 if climate change is unchallenged, according to a new assessment.
Its authors say understanding the way strong global heating affects polar ice sheets will be crucial to projecting sea level rise over the next century. However, uncertainties remain and current knowledge about ice sheets suggests sea-level rise under continued strong warming could be higher than the Intergovernmental Panel on Climate Change (IPCC) likely range by 2100.
The authors of the study, published today in the journal
One Earth, also suggest ways scientists can make predictions more certain, by improving our understanding of ice-sheet dynamics, such as how they interact with warming oceans and how they fracture and break apart.

Its authors say understanding the way strong global heating affects polar ice sheets will be crucial to projecting sea level rise over the next century. However, uncertainties remain and current knowledge about ice sheets suggests sea-level rise under continued strong warming could be higher than the Intergovernmental Panel on Climate Change (IPCC) ‘likely’ range by 2100.
If we don’t do more to avert dangerous global heating, we may reach a point where we can no longer protect people. Professor Martin Siegert
