This POSTbrief provides further information on current projections of future sea level rise. It introduces sea level rise projections and discusses the various future emissions scenarios used in the projections, the different modelling methods employed, as well as the likelihood ranges and uncertainties associated with them. It also provides an overview of the current sea level rise projections arising from different modelling techniques and emission scenarios and discusses high-end sea level rise scenarios.

This POSTbrief accompanies POSTnote 555 Rising Sea Levels.
