Future mean sea level - Based on data from IPCC AR6 SROCC (2019)

Future mean sea levels for Sweden's coast for the middle of the century (2050) and the end of the century (2100) are calculated for three different climate scenarios. GIS layers for the calculated mean water levels have been developed and show the location of the shoreline on average. The inventories are based on projections from the IPCC Special Report The Ocean and Cryosphere in a Changing Climate (SROCC) that was decided in September 2019. Inventories include the median, upper and lower boundary of the likely range of projected sea level rises under three different emission scenarios: RCP2,6, RCP4,5 and RCP8,5. The likely range is limited by the 17th and 83rd percentiles. Those levels therefore do not constitute either a lower or an upper limit for the possible level of the mean sea level in 2050 and 2100. A total of 252 stocks are available for download. Please note that newer bases have been developed. You can find it under the metadata entry "Future mean sea level - Based on data from IPCC AR6 WG 1 (2021)", https://www.smhi.se/data/explorer-oppna-data/future-mean-water-stand-based-pa-data-fran-ipcc-ar6-wg-1-2021. LIMITATIONS The geographical extent is limited to the area between the Swedish territorial boundary in the sea and 1.0 - 1.5 km inside the coastline. Comments: 1. The map data used in the calculations lacks detailed information on where there are or are missing natural or constructed obstacles or passages between land and sea. This means that land below future sea level may appear to be flooded even though there may be obstacles to flooding from the sea. 2. There are instances where land rise in parts of Sweden is greater than sea level rise. This means that the sea level in the near future will be lower than it is today. In these places, where land rises faster than the sea rises, the future sea level is shown as if it were unchanged, i.e. at the same level as today. 3. Possible effects on the coastline of a change in mean sea level (e.g. erosion) cannot be deduced from the map. SCOPE All data relates to Sweden. Coordinates for the area are given by the corners southwest 55.25N, 10.79E northeast 65.91N, 24.18E USE The inventories provide a comprehensive basis for information on future sea levels. The aim is not to provide a complete basis for decision-making, but to give an indication of the areas in which a more detailed basis should be developed. Please note that there are later calculations of future mean water levels than those found in this data material. Stocks show the shoreline of possible future mean sea levels in the middle of the century (2050) and the end of the century (2100). This is based on information on mean sea level during the reference period (1986-2005), sea level rise including regional variations and local land uplift. In the planning context, consideration should also be given to, among other things, high-water events that may occur, for example, during storms. High-water events are not included in these layers.
