Glaciers dominate eustatic sea-level rise in the 21st Century. Year-to-year trends vary, with some glaciers gaining mass in certain years (for example, Wolverine Glacier during the 1980s), but the measurements clearly indicate a loss of glacier mass over time. Under IPCC scenario RCP 8.5 (a more business-as-usual scenario), global sea level contributions from glaciers will be 216 44 mm by 2100 AD14. In context, that means that by 2100 AD, about half of all the Worlds glaciers will be gone unless strong mitigation strategies are employed. 317-382 (Cambridge University Press, 2013).
