Image: 2015-2100 Impacts of global warming on glaciers and sea level rise

Description: Chart illustrating effects of global warming of 1.5 °C and 4 °C on glaciers and sea level rise from 2015 to 2100 Source: Rounce, David R.; Hock, Regine; Maussion, Fabien; Hugonnet, Romain; Kochtitzky, William; Huss, Matthias; Berthier, Etienne; Brinkerhoff, Douglas; Compagno, Loris; Copland, Luke; Farinotti, Daniel; Menounos, Brian; McNabb, Robert W. (5 January 2023). "Global glacier change in the 21st century: Every increase in temperature matters". Science 379 (6627): 78-83. DOI:10.1126/science.abo1324. Source states in relevant part: "Glaciers are projected to lose 26 ± 6% (+1.5°C) to 41 ± 11% (+4°C) of their mass by 2100, relative to 2015, for global temperature change scenarios. This corresponds to 90 ± 26 to 154 ± 44 millimeters sea level equivalent and will cause 49 ± 9 to 83 ± 7% of glaciers to disappear. . . . Based on climate pledges from the Conference of the Parties (COP26), global mean temperature is projected to increase by +2.7°C, which would lead to a sea level contribution of 115 ± 40 millimeters and cause widespread deglaciation in most mid-latitude regions by 2100." Suggested caption: "Projections: Melting of glacial mass is approximately linearly related to temperature increase. Based on current pledges, global mean temperature is projected to increase by +2.7 °C, which would cause loss of about half of Earth's glaciers by 2100 with a sea level rise of 115±40 millimeters." Graphic shows: glacier mass loss on horizontal axis sea level rise on vertical axis fraction of glaciers forecast to be lost using the blue rings uncertainty intervals of glacier mass loss and sea leavel rise using the subtle gray rectangles; red-to-gray gradients merely fill the rectangles and do not represent any other quantity.
