Summary
| Description |
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. |

This figure was based on one originally prepared by Robert A. Rohde from publicly available data. See the Global Warming Art project for that and other figures by Robert A. Rohde. |

| 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
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.
