European annual average temperature deviations, 1850-2008, relative to the 1850-1899 average (in ºC). The lines refer to 10-year moving average, the bars to the annual 'land only' European average
The European 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. Europe is defined as the area between 35o to 70o Northern latitude, -25o to 30o Eastern longitude, plus Turkey (=35o to 40o North, 30o to 45o East). The resulting temperature anomalies were obtained using KNMI climate explorer.
