Reconstructed GMSL since 1880 as described in Church and White (2011). The papers describing this dataset are: Church, J. A. and N.J. White (2011), Sea-level rise from the late 19th to the early 21st Century. Surveys in Geophysics, doi:10.1007/s10712-011-9119-1. This paper is published "Open Access" and is available as a pdf: http://www.springerlink.com/content/h2575k28311g5146/ D. Masters , R. S. Nerem , C. Choe , E. Leuliette , B. Beckley , N. White & M. Ablain (2012): Comparison of Global Mean Sea Level Time Series from TOPEX/Poseidon, Jason-1, and Jason-2, Marine Geodesy, 35:sup1, 20-41. (DOI: 10.1080/01490419.2012.717862)   The time series is updated continuously (data available on the website).

Indicator Specification
Archived
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.

Global and European sea level This indicator comprises several metrics to describe past and future sea level rise 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 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.
