The left panel depicts the rise in global mean sea level from 1880 to 2019 based on two data sources. The red line (DMW) shows the hybrid sea-level reconstruction of sea level anomalies during 1900–2015 (Dangendorf et al., 2019). The uncertainty interval around is shaded. The dark blue line (CMEMS) shows the filtered sea level anomalies for the time period from 1993 to 2019 based on satellite observations (Ablain et al., 2017; WCRP Sea Level Budget Group, 2018). All values are relative to the average level of the period 1993-2012, during which the two datasets overlap. The right panel shows projections of global mean sea level until 2100 for three emissions scenarios based on the IPCC SROCC (Special Report on the Ocean and Cryosphere in a Changing Climate).
