Global annual average temperature deviations, 1850-2007, compared with the 1850-1899 average. The lines refer to 10-year moving average, the bars to the annual 'land and ocean' global average.
The global mean annual temperature deviations are in the source in relation to the base period 1961-1990. The annual deviations shown in the chart have been adjusted to be relative to the period 1850-1899 to better monitor the EU objective not to exceed 2oC above pre-industrial values. Over Europe average annual temperatures during the real pre-industrial period (1750-1799) were very similar to those during 1850-99.
