UNEP Grid Arendal
This visualization graphically displays temperature and CO2 concentration in the atmosphere as derived from ice core data from 400,000 years ago to 1950. The data originates from UNEP GRID Arendal's graphic library of CO2 levels from Vostok ice core.

Technical Details
Teaching Tips
- Can be complemented with related graphics, videos and activities on Milankovitch/orbital cycles and their role in the climate system. For example, http://www.learner.org/courses/envsci/visual/animation.php?shortname=anm_polar_icecores.
About the Content
- Graphic is slightly dated (2000) and could benefit from the inclusion of more recent ice core data going back 600K years from EPICA (Dome D).
- Comments from expert scientist: This webpage offers a graph of Vostok CO2 and Antarctic surface temperature, the latter reconstructed using deuterium (a hydrogen isotope) data. The graphs appear accurate and it is nice to have a simple figure showing these two datasets.
Technical Details/Ease of Use
- Easy-to-access image can be downloaded.
- The site hosting this graphic provides detailed information on the source of data, use constraints and citation suggestions.
