The state of climate in NW Iberia

Since 1974, there has been a significant increasing trend in land and sea surface temperatures of 0.5 and 0.24 degrees C decade(-1), respectively, in the NW Iberian Peninsula. Over the same period, annual precipitation does not show any trend, although some tendencies have been detected at seasonal...
