Brazil's Heat Waves Remain Neglected, Experts Warn

Heat waves in Brazil are a "completely neglected" disaster, according to researcher Renata Libonati. Despite 50,000 deaths caused by heat waves from 2000 to 2020, the issue receives little attention. Experts warn that a new El Niño may bring exceptionally high temperatures and exacerbate existing problems. The phenomenon may contribute to heat waves, droughts, and wildfires, particularly in the North, Northeast, and Central-West regions. Impacts vary across regions, with increased rainfall in the South and reduced rainfall in the North and Northeast. Experts emphasize the need for climate adaptation and preparation, particularly in cities, to minimize harm to the most vulnerable populations. Brazil's climate is already experiencing higher temperatures and more frequent extreme events, with an average temperature increase of nearly 2 °C above the global average.
