Global Threats Data (grid, shapefile)ZIP
Zip file contains the following data layers: -Acidification -Future thermal stress -Integrated future local and global threats -Past thermal stress The GIS data are in ArcMap shapefile format (for vector data), or ArcInfo GRID format (for raster data). All data are in a WGS 1984 Datum and a Cylindrical Equal-Area (Lambert) projection, with a Central Meridian at -160. Projects are included in each folder with datasets already loaded. Format for projects is ESRI ArcGIS ArcMap version 9.3.1. (.MXD) If you have ArcGIS 9.x or 10 installed on your machine, open ArcMap and navigate to the desired file. These files provide pointers to both the vector and GRID data on the CD. NB: These files are not compatible with version 8.x of ESRI's ArcGIS software.
Local & Global Threats in 2030 (KML)KMZ
Local & Global Threats in 2050 (KML)KMZ
Global (i.e., climate-related) threats to the world's coral reefs were analyzed. These include: past thermal stress (i.e., warming seas and bleaching over the last decade), future thermal stress (ie., projections of future warming in 2030 and 2050); and ocean acidification (i.e., reduced ocean pH in the present, 2030, and 2050). Future thermal stress and ocean acidification were integrated with local threats into the Integrated Local and Global Threat indices for 2030 and 2050. For additional information see: http://www.wri.org/sites/default/files/docs/reefs_at_risk_revisited_technical_notes.pdf.
The data files include GIS data sets and KML files for use in Google Earth and other map applications that support KML.
See the README file for source information.
The model relies on available data and predicted relationships but cannot capture all aspects of the dynamic interactions between people/environment and coral reefs. The threat indicators gauge current and potential risks associated with human activities/climate change. A strength of the analysis lies in its use of regionally consistent data sets to develop globally consistent indicators of human pressure on coral reefs. However, the model is not perfect, and omissions and other errors in the data sets are inevitable.
