Five-year average global temperature anomalies. This dataset shows the departure from normal for temperatures from 1884 through 2008. In this case, normal is the 1951-1980 mean temperature. Five-year averages are used for the yearly temperatures to account for year-to-year variability. The warmest year in this record is 2005. Over the past 30 years, there has been a rapid warming trend. In fact, eight of the warmest years have been recorded since 1998. The greatest warming has been observed in the Arctic. Areas that are dark red indicate the greatest warming, while dark blue areas indicate the greatest cooling. The temperature varies from 2 degrees Celsius below normal to 2 degrees Celsius above normal. | |
