"The international team of scientists said a primary cause of the deaths was inequality and inadequate urban planning, which created landslide vulnerabilities for poor communities dwelling on steep, deforested and poorly drained hill slopes. Juiz de Fora is one of the 10 riskiest cities in Brazil in terms of the proportion of residents living in such danger zones.

The intensity of the downpour in the city was also exceptional, calculated by the experts as a one-in-several-hundred-year event. While the scientists were unable to determine a clear fingerprint of human-driven climate disruption in this instance, they found that downpours in the area would be expected to become 7% more severe if the planet reached 2.6C of heating above preindustrial levels, up from the current level of about 1.3C."
