This figure appears in chapter 12 of the Climate Science Special Report: The Fourth National Climate Assessment: Volume I report.

(a) The relationship between peak global mean temperature, maximum global mean sea level (GMSL), and source(s) of meltwater for two periods in the past with global mean temperature comparable to or warmer than present. Light blue shading indicates uncertainty of GMSL maximum. Red pie charts over Greenland and Antarctica denote fraction, not location, of ice retreat. Atmospheric CO₂ levels in 2100 are shown under RCP8.5 (b) GMSL rise from −500 to 1900 CE, from Kopp et al.’sa0130167-b319-493d-bedc-7cab8f8fe9d9 geological and tide gauge-based reconstruction (blue), from 1900 to 2010 from Hay et al.’s7c318710-b8fb-4e09-9982-546f2b60be67 tide gauge-based reconstruction (black), and from 1992 to 2015 from the satellite-based reconstruction updated from Nerem et al.7b7ffcb0-766c-43b3-ac22-db29fbffef71 (magenta).
