- Description: Atmospheric carbon dioxide concentration and mean global temperature during the past 1000 years. Carbon dioxide levels (blue line, left-hand axis) are given in parts per million (volume), temperatures (red line, right-hand axis) in degrees centigrade.
- 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.
