Description
English: 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.
  • SVG code for background of chart was was automatically generated using a spreadsheet linked at User:RCraig09/Excel to XML for SVG. The graphed content was manually added using a text editor.
