Indicator Specification Global and European temperatures This indicator shows observed and projected changes in annual average near-surface temperature globally and for Europe. Europe is defined here as the land area in the range 34° to 72° northern latitude and -25° to 45° eastern longitude. Temperature anomalies are presented relative to a ‘pre-industrial’ period between 1850 and 1899 (the beginning of instrumental temperature records). During this period, greenhouse gases from the industrial revolution are considered to have had a relatively small influence on the global climate compared with natural influences. Time series of global and European land temperatures in Figure 1 are provided both as annual values (top) and as decadal averages (bottom).

Global and European temperature This indicator shows absolute changes and rates of change in average near-surface temperature for the globe and for a region covering Europe. Near-surface air temperature gives one of the clearest and most consistent signals of global and regional climate change, especially in recent decades. It has been measured for many decades — even centuries at some locations — and a dense network of stations across the globe, especially in Europe, provides regular monitoring of temperature, using standardised measurements, quality control and homogeneity procedures. Global average annual temperature deviations (anomalies) are discussed relative to a ‘pre-industrial’ period between 1850 and 1899 (the beginning of instrumental temperature records). During this time, anthropogenic greenhouse gases from the industrial revolution (between 1750 and 1850) are considered to have had a relatively small influence on the climate compared with natural influences. However, it should be noted that owing to earlier changes in the climate due to internal and forced natural variability, there was not one single pre-industrial climate and it is not clear that there is a rigorous scientific definition of the term ‘pre-industrial climate’. Temperature changes also influence other aspects of the climate system that can have an impact on human activities, including sea level, intensity and frequency of floods and droughts, biota and food productivity, and infectious diseases. In addition to the global average target, seasonal variations and spatial distributions of temperature change are important, for example, to understand the risks that the current climate poses to human and natural systems, and to assess how these may be impacted by future climate change.
