European average air temperature anomalies (1850 to 2012) in °C over land areas only

The sources of the original data: 1) Black line - HadCRUT4 from the UK Met Office Hadley Centre and University of East Anglia Climate Research Unit, baseline period 1850-1899 (Morice et al. 2012) with the grey area representing the 95% confidence range, 2) Red line – MLOST from the US National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Centre, baseline period 1880-1899 (Smith et al., 2008), and 3) Blue line - GISSTemp from the National Aeronautics and Space Administration (NASA) Goddard Institute for Space Studies, baseline period 1880-1899 (Hansen et al., 2010). Upper graph shows anomalies and lower graph shows decadal average anomalies for the same datasets.
Europe is defined as the area between 35° to 70° North and -25° to 30° East, plus Turkey (35° to 40° North and 30° to 45° East).
