Projected Sea Ice Concentration change based on CMIP5 multi-model ensembles

Projected Sea Ice Concentration change based on CMIP5 multi-model ensembles Seasonal and annual multi-model ensembles of projected change (also known as anomalies) in sea ice concentration based on an ensemble of twenty-eight Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models are available for 1900-2100. Sea ice concentration is represented as the percentage (%) of grid cell area. Therefore, projected change in sea ice concentration is with respect to the reference period of 1986-2005 and expressed as a percentage (%). The 5th, 25th, 50th, 75th and 95th percentiles of the ensembles of sea ice concentration change are available for the historical time period, 1900-2005, and for emission scenarios, RCP2.6, RCP4.5 and RCP8.5, for 2006-2100. Twenty-year average changes in sea ice concentration (%) for four time periods (2021-2040; 2041-2060; 2061-2080; 2081-2100), with respect to the reference period of 1986-2005, for RCP2.6, RCP4.5 and RCP8.5 are also available in a range of formats. The median projected change across the ensemble of CMIP5 climate models is provided. Note: Projections among climate models can vary because of differences in their underlying representation of earth system processes. Thus, the use of a multi-model ensemble approach has been demonstrated in recent scientific literature to likely provide better projected climate change information. 2024-05-15 Environment and Climate Change Canada ec.ccds.info-info.dscc.ec@canada.ca Nature and EnvironmentScience and TechnologyProjections; climate; climate change; percentiles; ensembles; climate model; sea ice; cmip5; anomalyClimateClimate changeWeather and ClimateProvide Climate Information Products and ServicesExpand Scientific Knowledge for Climate Monitoring and PredictionNational (CA)Science and Technology BranchAtmospheric Science and TechnologyUnclassified View Data MartHTML https://dd.weather.gc.ca/climate/cmip5 View Data MartHTML https://dd.meteo.gc.ca/climate/cmip5 Climate Data ViewerHTML https://climate-viewer.canada.ca/climate-maps.html Climate Data ViewerHTML https://visualiseur-climatique.canada.ca/cartes-climatiques.html Climate Data Extraction ToolHTML https://climate-change.canada.ca/climate-data/#/cmip5-data GeoMet WMS (EN)WMS https://geo.weather.gc.ca/geomet-climate?service=WMS&version=1.3.0&request=GetCapabilities GeoMet WMS (FR)WMS https://geo.weather.gc.ca/geomet-climate?lang=fr&service=WMS&version=1.3.0&request=GetCapabilities GeoMet WCS (EN)TAB https://geo.weather.gc.ca/geomet-climate?service=WCS&version=2.0.1&request=GetCapabilities GeoMet WCS (FR)TAB https://geo.weather.gc.ca/geomet-climate?lang=fr&service=WCS&version=2.0.1&request=GetCapabilities Canadian Climate Data and Scenarios ENNetCDF https://climate-scenarios.canada.ca/index.php?page=main Canadian Climate Data and Scenarios FRNetCDF https://scenarios-climatiques.canada.ca/index.php?page=main Data Collection MethodologyPDF https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/projected-sea-ice-concentration-change-based-on-cmip5-multi-model-ensembles/CMIP5_-_READ_ME_Technical_Doc_EN.pdf Data Collection MethodologyPDF https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/projected-sea-ice-concentration-change-based-on-cmip5-multi-model-ensembles/CMIP5_-_READ_ME_Technical_Doc_FR.pdf View ECCC Data Mart (English)HTML https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/projected-sea-ice-concentration-change-based-on-cmip5-multi-model-ensembles/ View ECCC Data Mart (French)HTML https://data-donnees.ec.gc.ca/data/climate/scientificknowledge/projected-sea-ice-concentration-change-based-on-cmip5-multi-model-ensembles/?lang=fr
