\nBroad estimates of global mean sea level rise by the year 2100 due to global warming vary depending on emission scenarios and models. While projections range from about 30 cm to over 1 meter, 40 cm falls within the plausible range often cited as a lower-to-mid estimate in various assessments or as a rounded figure representative of a significant, yet not extreme, rise within the century.
\n<\/section>\n
\n– Sea level rise is caused primarily by the thermal expansion of seawater and the melting of glaciers and ice sheets.
\n– Projections for sea level rise are based on climate models and future greenhouse gas emission scenarios.
\n– The Intergovernmental Panel on Climate Change (IPCC) reports provide detailed projections with associated uncertainty ranges for different scenarios.
\n<\/section>\n
\n– The IPCC AR6 report (2021) projects a *likely* global mean sea level rise by 2100 (relative to 1995\u20132014) of 28\u201355 cm under a very low emissions scenario (SSP1-1.9) and 63\u2013101 cm under a very high emissions scenario (SSP5-8.5).
\n– 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.
