How accurate are the worst-case sea level rise maps, and what are their limitations?

Answers

The accuracy of worst-case sea-level rise projections is inherently limited by the complexity of the underlying physical processes. We are dealing with a coupled system of atmospheric, oceanic and cryospheric interactions that are not entirely understood, making definitive predictions challenging. The current generation of ice sheet models still struggles to capture the full range of potential instability mechanisms. Furthermore, the omission of certain feedback processes and compounding factors can lead to underestimation of the actual risks. It is critical to acknowledge that these maps represent high-end scenarios rather than probabilistic forecasts and highlight the potential for substantial societal and environmental disruptions. The best use of this information is not in deterministic prediction but in risk management and adaptation planning, allowing communities and infrastructure to prepare for a range of potential outcomes, including those at the upper end of the projection range.

Worst-case sea level rise maps aren't perfectly accurate due to uncertainties in ice sheet melt and regional factors. They show high-end scenarios, not guaranteed outcomes.
