English: This image shows the instrumental record of global average temperatures as compiled by the NASA's Goddard Institute for Space Studies. The data set used follows the methodology outlined by Hansen, J., et al. (2006) "Global temperature change". Proc. Natl. Acad. Sci. 103: 14288-14293. |

Dragons flight's Temperature Record Series |
This figure is part of a series of plots created by Dragons flight to illustrate changes in Earth's temperature and climate across many different time scales. |
Time Period: 25 yrs | 150 yrs | 1 kyr | 2 kyr | 12 kyr | 450 kyr | 5 Myr | 65 Myr | 500 Myr |

Plot Generation
[edit]This plot was generated using python, and the matplotlib library for python. The following code, which will fetch the latest data directly from the Climatic Research Unit, was used. The same code can be used to re-generate new plots as necessary to accommodate more recent data as needed.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
