Valencia floods: Warming climate is making once-rare weather more common and more destructive, says researcher

In the last few days, a seasonal weather system known in Spain as the "cold drop" or DANA (an acronym of "depresión aislada en niveles altos": isolated depression at high levels) has caused heavy rain and flooding across Spain's Mediterranean coast and in Andalusia, especially in the Valencian Community, Castilla-La Mancha and the Balearic Islands. The storm has left hundreds dead and many more missing, with immense damage in the affected areas.
