Caverna no Paran� revela influ�ncia da Ant�rtida e do El Ni�o em chuvas extremas no Sul do Brasil

Researchers have discovered a cave in Paraná that serves as a "climate archive," revealing the history of extreme rainfall in southern Brazil over the last 7,500 years. The findings indicate that the frequency of these events in the 20th century is among the highest in the entire historical record. This data points to the influence of Antarctic climate variability and El Niño occurrences, both of which are relevant today as climate patterns continue to evolve. This insight is crucial for understanding and predicting future weather trends in the region.
