Summary

Description

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. Following the common practice of the IPCC, the zero on this figure is the mean temperature from 1961-1990. The graph shows an overall long-term warming trend. In the 1880s, the global temperature anomaly was on average slightly below -0.4 °C, while in the first decade of the 21st century, the anomaly was on average almost +0.5 °C. This figure was originally prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.
