Effects of human-caused global heating are blocking vital winter rains, with severe implications for farming and tourism
Spain and Portugal are suffering their driest climate for at least 1,200 years, according to research, with severe implications for both food production and tourism.
Most rain on the Iberian peninsula falls in winter as wet, low-pressure systems blow in from the Atlantic. But a high-pressure system off the coast, called the Azores high, can block the wet weather fronts.
