A heatwave has struck Brazil’s southernmost state of Rio Grande do Sul, forcing the postponement of school classes due to inadequate ventilation and water supplies. The region is experiencing record-breaking temperatures, with the highest temperature recorded in February at 43.8C (110.8F).
The heatwave comes amid a severe drought that has affected over 60 municipalities in the state. Scientists say the current heatwave and last year’s floods are “potentially linked to the climate crisis”, as extreme weather events become more frequent and intense.
Teachers’ unions argue that many schools lack air conditioning, which would help mitigate the effects of the heatwave. The Olindo Flores school in São Leopoldo had air conditioning installed before its destruction in last year’s floods, but it remains without replacement.
A court ruling suspended classes for at least a week, while an appellate judge later ruled that they could resume on Thursday when a cold front is expected to arrive. However, teachers say the issue will persist and they will continue to fight for air conditioning installations in all schools.
The region’s milder climate is unusual compared to other Brazilian regions closer to the equator. As temperatures rise, it becomes increasingly difficult for living beings to adapt to such rapid changes, according to meteorologist Marina Hirota.
