Wildfires in Brazil's southern Sao Paulo state have resulted in at least two fatalities and left 36 cities on high alert as firefighters struggle to control the flames exacerbated by a heat wave and prolonged drought. The Sao Paulo state government has deployed over 7,300 workers and volunteers to combat the fires, with efforts intensified amid reports of significant smoke affecting visibility and disrupting transportation. Governor Tarcisio de Freitas announced the establishment of a crisis cabinet to coordinate firefighting efforts, declaring that the region is experiencing some of its worst wildfires in decades. The fires have also led to the cancellation of outdoor sports events, with smoke triggering health concerns in urban areas, including the capital, Sao Paulo. As the situation unfolds, the government has indicated that conditions may worsen due to strong winds, further complicating firefighting efforts. The wildfires come at a time when Brazil is grappling with extreme weather events, including earlier fires in the Pantanal wetlands and severe flooding in other regions.
