In southeastern Brazil, at least three dozen people were killed over the weekend as heavy rains triggered landslides and flash flooding in coastal São Paulo state. Some areas received more than two feet of rain in just 24 hours, in what meteorologists called an unprecedented extreme weather event.

In New Zealand, at least 11 people are dead and thousands remain unaccounted for, one week after Cyclone Gabrielle left a trail of devastation along New Zealand’s North Island. Prime Minister Chris Hipkins blamed climate change for the scale of the damage, calling it New Zealand’s worst natural disaster of the century.

Meanwhile, Madagascar is bracing for Cyclone Freddy, one month after a devastating tropical storm killed 30 people. Freddy is an extremely rare and long-lived cyclone — just the third ever recorded crossing the Indian Ocean.
