_{GLOBAL MEAN TEMPERATURES}

Patterns of linear global temperature trends 1979 to 2005 estimated at the surface (left), and for the troposphere from satellite records (right). Grey areas indicate incomplete data. Bottom: The annual global mean temperatures (black dots) are given along with simple fits to the data. The red line is a linear trend fit to the complete 1850–2005 record and the blue line is a smoothed depiction to capture the decadal variations, and with decadal 95% (yellow) error range about that line. The temperature change from the first 70 years of the instrumental record (1850–1919) to the last 5 years (2001–2005) is 0.78 ± 0.18ºC.
