Vulturno by Jorge Aznar

How much of an increase in temperatures in Spain because of climate change?
I analysed the temperatures increase in 47 stations of AEMET(State Meteorological Agency in Spain). The data came from Open Data AEMET since 1950 to today.

When in the year was it registered the highest temperature recorded of each day of the year? Was it this century or the past century?
How many tropicals night has every city had?
How much frost has every city had?
How many days over 40ºC(104℉) temperature in every year?
