Five-Year Average Global Temperature Anomalies for 1888,1918,1948,1978, 2008

Each year, scientists at NASA Goddard Institute for Space Studies analyze global temperature data. A rapid warming trend has occurred over the past 30 years. Calendar year 2008 was the coolest year since 2000, according to the Goddard Institute for Space Studies analysis of surface air temperature measurements. In this analysis, 2008 is the ninth warmest year in the period of instrumental measurements, which extends back to 1881. 2005 is the hottest year on record, and 2007 is tied with 1998 for second place. The Earth is experiencing the warmest level of the current interglacial period, or interval between ice ages, which has lasted nearly 12,000 years. This color-coded map displays a long term progression of changing global surface temperatures, from 1881 to 2008. Dark red indicates the greatest warming and dark blue indicates the greatest cooling.
