Temperature Anomaly
Figure 8: Global temperature anomalies for 2000 to 2009. Temperature anomalies do not depict absolute temperature, but rather how much warmer or colder a region is compared to the norm for that region from 1951 to 1980. Global temperatures from 2000–2009 were on average about 0.6°C higher than they were from 1951– 1980. The Arctic, however, was about 2°C warmer.[fn][[nid:344]][/fn]
