This handout picture released by the Brazilian Presidency shows an aerial view of Porto Alegre, Brazil, with the Arena do Gremio stadium (top, R), taken on May 5, 2024, during an overfly by Brazil's President Luiz Inacio Lula da Silva of areas affected by floods triggered by torrential storms in the southern Rio Grande do Sul State. Authorities in southern Brazil scrambled Sunday to rescue people from raging floods and mudslides in what has become the region's largest ever climate catastrophe, with at least 78 dead and 115,000 forced from their homes. Entire cities were underwater, with thousands of people cut off from the world by the floodwater, brought by days of torrential rains.
