Average temperature in Spain has risen by 0.55ºC in 50 years

SPAIN (Agencies) According to AEMET, the national meteorologic agency, the average temperature in Spain has risen by only a half percentage point in 50 years. In a recent report, the agency pointed out that this is an overall figure. The reality, as is perceived by most people, is that, for instance, the average temperature between 1971 to 2000 went up by 0.22%, whereas in the 1981-2010 period it rose by 0.46%, over twice the amount of that observed in the two periods of prior reference. The average mean temperature in Spain, then, was 15.09ºC for the 1981-2010, against 14.63ºC for 1971-2000, and 14.43ºC for 1961-1990. As for rainfall>>>

statistics, there has been no significant change overall, with the average staying at the 648mm (litres per square metre). This data is consistent with forecasts for the future, which point to a rise in temperature of between 3 and 5ºC by the end of the century, depending on various factors, including that rainfall is expected to diminish considerably in Spring and Summer, yet compensated by an increase in rainfall in Autumn and Winter.

Although these figures point to an acceleartion in the rise of temperatures over the last couple of decades, the report says that three important factors should be taken into account: the 1970s were particularly cold; the way and places temperatures and other meteorological items are measured may well have changed since the 1950s; and the last 15 years have been the hottest registered yet. Although there are exceptions, an example of this is 2010, which on a global level was the hottest, together with 1998 and 2005 (data: World Metereological Organization http://www.wmo.int/pages/index_en.html), in Spain it was the coldest since 1996.
