Scientific organizations like the Intergovernmental Panel on Climate Change (IPCC) are publishing sea level rise projections with increasing levels of confidence.

By 2300, seas could stand as much as 5 meters higher under the worst-case scenario. If countries do cut their emissions significantly, the IPCC expects 0.3 to 0.6 meters of sea level rise by 2100.
