Figure Past trend and projected change in relative sea level across Europe Trends: The arrows show the observed trend in sea level relative to land since 1970 for those tide gauges along the Europe coastline with sufficiently long time series. Projections: European sea level change for 2081–2100 for SSP5-8.5 in metres. Results use CMIP6 model projections for long term scenario (2081-2100), for SSP5-8.5, and with respect to a baseline of 1995-2014.

Past trend and projected change in relative sea level across Europe The arrows show the trend in relative sea level at selected European tide gauge stations since 1970 (in mm/year) based on data from the Permanent Service for Mean Sea Level (PSMSL). The background colours show projections of European sea level change for 2081–2100 for RCP8.5 (in metres). Results are median values based on the values in the IPCC SROCC Table 4.4.

Trend in relative sea level at selected European tide gauge stations The map shows the trend in relative sea level at selected European tide gauge stations since 1970. These measured trends are not corrected for local land movement. No attempt has been made to assess the validity of any individual fit, so results should not be treated as suitable for use in planning or policymaking. Geographical coverage reflects the reporting of tide gauge measurements to the Permanent Service for Mean Sea Level (PSMSL).

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.

The following components on observed sea-level rise are included: Change in global mean sea level (time series starting in 1880, in mm), based on a reconstruction from various data sources (since 1880) and on satellite altimeter data (since 1993) Trend in absolute sea level across Europe (map, in mm/year), based on satellite measurements (since 1992) Trend in relative sea level across Europe (map, in mm/year), based on selected European tide gauge stations (since 1970) Furthermore, this indicator presents projections for sea level rise in the 21st century, both globally and for the European seas. The indicator also presents the contributions to past and future global sea level rise from different sources. Finally, the indicator presents information on observed and projected changes in extreme sea level along European coasts. However, due to insufficient data availability this information cannot be presented by means of figures or maps.
