Produced figures

Figure Observed and projected change in global mean sea level 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).

Used in indicators

Indicator Specification Global and European sea level rise This indicator comprises several metrics to describe past and future sea level rise globally and along European coastlines: observed change in global mean sea level, based on reconstructions from tide gauge measurements (since 1900) and on satellite altimeter data (since 1993); projected change in global sea level for three different forcing scenarios; spatial trends in relative sea level along the European coastline, based on tide gauge stations with long time series (since 1970); and projected change in relative sea level across European seas

Global and European sea-level rise This indicator comprises several metrics to describe past and future sea level rises globally and in European seas. Global sea level rise is reported because it is the second-most important metric of global climate change (after global mean surface temperature), and because it is a proxy of sea level rise in Europe. Past sea level trends across Europe are reported in two different ways: first, absolute sea level change based on satellite altimeter measurements that reflect primarily the contribution of global climate change to sea level rise in Europe; second, relative sea level change based on tide gauges that also include local land movement, which is more relevant for the development of regional adaptation strategies. The indicator also addresses changes in extreme sea level along the European coast. The following aspects of sea level rise are included: observed change in GMSL, based on two reconstructions from tide gauge measurements (since 1880) and on satellite altimeter data (since 1993); spatial trends in absolute sea level across European seas, based on satellite measurements (since 1993); spatial trends in relative sea level across European seas, based on European tide gauge stations with long time series (since 1970); projected change in global sea level for three different forcing scenarios; projected change in relative sea level across European seas; projected change in the frequency of flooding events along European coasts.
