"SAO PAULO - Record floods that killed over 170 people and displaced half a million in southern Brazil are a warning sign of more disasters to come throughout the Americas because of climate change, an official at the United Nations' refugee agency said on Tuesday.
Roughly 389,000 people in the state of Rio Grande do Sul remain displaced from their homes because of the intense rain and flooding, which local officials say was the worst disaster in the region's history. Scientists say climate change made the flooding twice as likely to happen.
Andrew Harper, special advisor on climate action to the refugee agency UNHCR, visited a flooded neighborhood in state capital Porto Alegre over the weekend and called it "a ghost town."
"It was underwater for almost 40 days. There wasn't even any rats running around. Everything had died," Harper said in an interview on Tuesday."
