Source graph drawn by Hanno using data from different sources. For the temperature data, see Global temperature 1ka.png. CO2 levels are based on historical carbon dioxide records from ice cores drilled at the Law Dome in Antarctica, published on the web by D.M. Etheridge, L.P. Steele, R.L. Langenfelds & R.J. Francey (1998) as "Historical CO2 records from the Law Dome DE08, DE08-2, and DSS ice cores". In Trends: A Compendium of Data on Global Change.

This graph image could be recreated using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file "CO2-Temp.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.
