Climate Solutions Explorer - hazard, impacts and exposure data

This is a pre-release dataset and is subject to change. The Climate Solutions Explorer website maps and presents information about mitigation pathways, avoided climate impacts, vulnerabilities and risks arising from development and climate change. www.climate-solutions-explorer.eu Using the latest data, state-of-the-art models were used to assess the future trends of indicators of development- and climate-induced challenges. Updated gridded global climate and impact model data are based on CMIP6 and CMIP5 projections, using a subset of models from the ISIMIP project that have been consistently downscaled and bias-corrected. The data includes various indicators (~30) relating to extremes of precipitation and temperature (e.g. from Expert Team on Climate Change Detection and Indices), hydrological variables including runoff and discharge, heat stress (from wet bulb temperature) events (multiple statistics and durations), and cooling degree days, as well as further indicators relating to air pollution (PM2.5 from the GAINs model), and crop yields and natural habitat land-use change (biodiversity pressure) from the GLOBIOM model. Indicators were calculated at a spatial resolution of 0.5° (approximately 50km at the equator), and subsequently spatially aggregated to the country level – from which population and land area exposure to the impacts were calculated. This has enabled the country-by-country comparison of national climate impacts and avoided exposure. Impacts were calculated at global mean temperature intervals, i.e. 1.2, 1.5, 2, 2.5, 3, and 3.5 °C, compared to a pre-industrial climate. The dataset includes: Global gridded projections (in netcdf format) of all the climate impact indicators at 0.5° spatial resolution, at global warming levels of 1.2, 1.5, 2, 2.5, 3, and 3.5 °C For each GWL, maps for the absolute indicator values, the relative difference, and the scores are provided. The naming format is: [short_indicator_name]_[ssp]_[gwl]_[metric].nc4. Included in the .zip files are also the intermediate output files containing the multi-model ensemble statistics for the GWLs and the reference period. The naming format for these files is either [ISIMIP protocol]_MM_[short_indicator_name].nc4 for the GWLs or [ISIMIP protocol]_MM_historical_[short_indicator_name] for the reference period. Tabular data (Excel .csv) is also provided, aggregating the impact indicators to the country level, for both hazards and exposure (both population and land) The .zip archive ‘table_output_climate_exposure.zip’ contains the tabular data for all indicators. For each indicator, two csv files are provided: one for country-level data and one for the R10 regions and the EU. Heatwave and precipitation indicators are grouped into one file. Further details on the methodology and indicator definitions are available on the Data Story page – www.climate-solutions-explorer.eu/story/data. Release Notes (v0.4) Changes in this version: Removed spp and metric from variable name in netCDF files Removed obsolete coordinates in netCDF files for 'Drought intensity' Added intermediate outputs for energy, hydrology, precipitation, and temperature indicators
