Atmospheric greenhouse gas concentrations 2000-2100.png greenhouse gas GHG concentrations between the years 2000 and 2100 for a range of climate change mitigation scenarios GHG concentrations are measured in carbon dioxide-equivalents GtCO<sub>2</sub>-eq in units of parts-per-million by volume ppmv Concentrations include the full basket of GHGs as well as other radiatively active gases such as aerosol and aerosol precursors Projections for 5 scenarios are shown Each scenario is designed to stabilize atmospheric GHG concentrations at a different level 450 520 670 970 and 1390 ppmv A summary table of the graph data is given in a later section References Scenario data can be freely downloaded from International Institute for Applied System Analysis IIASA http //www iiasa ac at/web-apps/ggi/GgiDb/dsd Action htmlpage page about GGI Scenario Database Ver 2 0 2009 Archived https //web archive org/web/20131004192147/http //www iiasa ac at/web-apps/ggi/GgiDb/dsd Action htmlpage page about 4 October 2013 These are the A2r mitigation scenarios 2014-10-29 08 35 48 own Enescot other versions Data Atmospheric GHG concentrations for scenarios 2000 to 2100 wikitable sortable - Scenario Year<br/>2000 2030 2050 2100 - 450 ppmv 369 2 475 5 512 6 441 7 - 520 ppmv 369 2 484 0 548 3 515 1 - 670 ppmv 369 2 492 8 600 1 675 1 - 970 ppmv 369 2 498 7 650 3 985 0 - 1390 ppmv 369 2 502 9 682 9 1349 7 cc-zero Uploaded with UploadWizard Greenhouse gases | ||||
