Update: the warming trend for the last 50 years is 0.13oC per decade, nearly twice that for the previous 100 years. The total global average temperature increase from 1850-2005 is now 0.76oC.
Anomalies are often used, rather than absolute measures, as the nature of the data frequently shows changes in quantities better than absolute. The anomaly is plotted against some reference figure, in this case the 1961 to 1990 average temperature. As shown, global average surface temperatures have been higher than this average for at least 20 years. Also, since 1979, land temperatures have increased about twice as fast as ocean temperatures, 0.25oC per decade against 0.13oC per decade respectively (Smith, 2005). Update: 11 of the last 12 years (1995-2006) were among the warmest on the surface temperature record.
