Still reeling a year on, Brazil's Porto Alegre fears next flood

As residents continue to repair damage nearly 12 months after Rio Grande do Sul's worst-ever natural calamity, they worry not enough is being done to buttress the city against another such catastrophe, which experts say is made ever more likely by climate change. In late April and early May 2024, three months' worth of rain fell on the wealthy state, of which Porto Alegre is the capital, in just 10 days. The brunt of the deluge was felt in the city of 1.3 million people located on the shores of Lake Guaiba, which is fed by four rivers.
