The effects of Climate Change are already visible in Spain; around 25% less rain falls nowadays than 50 years ago, and average temperatures have risen by as much as 8 °C in some regions. This leads to higher rates of evaporation, which in turn leads to heavier rainfall and flooding. In the last 20 years alone, it is estimated that the country has lost 20% of its freshwater supply, the water table has dropped dramatically, and what little glacial ice remains in the Pyrenees (90% has already been lost) is melting away at a rapid pace.
