Climate change in the regions of Valencia and Murcia: the analytical trace of a real Trojan horse

The main goal of this research has been to establish the value of regional climate trends. Rigorous homogenization and correction of climatic time series (SNHT) suggests that, since the mid-twentieth century the Mediterranean observatories has showed a rise in temperatures. The value of this trend would have been less than 0.4 ºC over the period 1950-2008. A thermal increase, according to the behavior of the maximum and minimum temperatures, could be induced very likely by increased solar activity. The small magnitude of this heating could also explain the behavior of rainfall not showing significant trends.
