In several towns, streets essentially turned into rivers, with roads and bridges destroyed. The storm also triggered landslides and the partial collapse of a dam structure at a small hydroelectric power plant. Heavy rains battering Brazil’s southernmost state of Rio Grande do Sul have killed 31 people and the death toll is expected to rise as dozens still have not been accounted for. More than 70 people were still missing and at least 17,000 were displaced in the state bordering Uruguay and Argentina, which had nearly half of its 497 cities affected, according to Rio Grande do Sul’s civil defense. Can the floods be attributed to effects of climate change ?
