Brazil continues to face significant challenges regarding climate vulnerability and extreme weather patterns. Discussions on environmental racism have highlighted how race and income levels influence susceptibility to natural disasters, such as flooding, in peripheral urban areas like Guarulhos and São Paulo. To address these inequalities, seminars in Rio de Janeiro have focused on climate justice and protection policies for vulnerable groups, including indigenous peoples and favela residents. Meteorologists and researchers are increasingly warning of the severe, neglected impact of heatwaves. Professor Renata Libonati of UFRJ reported that between 2000 and 2020, approximately 50,000 deaths were linked to heatwaves across 14 metropolitan regions, a figure she noted is “20 times higher than deaths caused by landslides in the same period.” The expected influence of the El Niño phenomenon is predicted to intensify these extreme temperatures, potentially leading to exceptionally high temperatures in 2026 and increasing the frequency of droughts and wildfires. Regional instability remains varied, with storms expected in the South and low humidity levels persisting in the Central-West and Southeast regions. Recent reports confirm these trends, noting that Goiás has recorded temperatures reaching 41.4°C amid dry conditions and low humidity, while the South continues to experience storms and instability driven by El Niño.
