SOS is seen written on a truck at a flooded area at Diego de Almagro town
SOS is seen written on a truck at a flooded area at Diego de Almagro town, March 28, 2015. The heavy rainfall that battered Chile's usually arid north this week happened because of climate change, a senior meteorologist said, as the region gradually returns to normal after rivers broke banks and villages were cut off. The word at left reads "Rescue". REUTERS/Ivan Alvarado
