– Projections for sea level rise are based on climate models and future greenhouse gas emission scenarios.
– The Intergovernmental Panel on Climate Change (IPCC) reports provide detailed projections with associated uncertainty ranges for different scenarios.
– The options provided (10, 20, 30, 40 cm) are relatively low compared to the midpoints of even the lowest IPCC ranges, but 40 cm is the highest option and falls within the lower part of the range projected under moderate emission scenarios by earlier reports or as a rounded figure. Given the options, 40 cm is the most reasonable “broad estimate” among the choices.
