"Brazil's Cerrado Faces Worst Drought in 700 Years, Study Reveals"
A study by the University of São Paulo reveals that Brazil's Cerrado is experiencing its worst drought in at least 700 years, driven by global warming. The research, published in Nature Communications, used geological data from caves to extend climate records and found significant hydrological disruptions due to rising temperatures. The drought is unprecedented and expected to worsen, affecting the São Francisco River basin and altering the chemistry of cave formations.
