AEMET Data: Temperature in Spain has risen in 70 years
AEMET Details: The temperature in Spain has risen in 70 years Since 1930, temperatures in Spain have not suffered neither a promotion nor a significant decrease. Thanks to data from the English Meteorological Agency itself detected a few tenths of warming in some areas (mainly urban) and cooling in other 01/12/2010

The study was carried out by the blog From Exile, has prepared a comparison of the data provided by the website of the English Agency for Meteorology , on Temperatures in Spain from 1971 to 2000.
From the blog draws attention to the state agency not provide temperature data for previous periods the period 1971-2000. However, these data are collected in the book Guide Climate Summary, available on paper, which was released in 1982 and includes results related to the period 1931 to 1960.
From Exile alert to compare the two guides, it is noted that the network of observatories that collect temperature results have changed, so r esultaría misleading to compare the national average for each of the periods 30 years. Should also be taken into account the location of the observatories, as those in the center of the city are influenced by the effect of heat island. "
Therefore, the only way to make a comparison minimally serious is judged on a case by case, observatory observatory and then draw appropriate conclusions.
Taking the example of Madrid , been noted that the observatories in the 30-60 period still exist, they have shifted their location and remain part of the Home Network. The observatories of Retiro, Madrid Barajas Airport and Puerto de Navacerrada
For Retirement , the average temperature has increased 7 / 10, specifically 13.9 to 14.6. To test whether this increase is due to the effect "heat island" should be compared with other observatories in Madrid.
In Puerto de Navacerrada local warming is negative, the 1930-60 average is 6.5 while that for 1970-2000 is 6.4. One-tenth less. So is the Barajas Airport has also declined, the average 30 to 60 is 14.4 and 70 to 00 from 14.1. Three tenths !
The same happens in the rest of Spain, a few tenths of increase in some places (usually coinciding with urban observatories) and a few tenths down on others. Neither heating or cooling, at least in significant levels.
addition to calling attention to these conclusions, everything is significant that AEMET not expose these results on the web, and yet accommodate itself to studies such as "global warming" which is available at
