A new study co-authored by CSUDH Professor of Earth Science Ashish Sinha reveals that catastrophic droughts–unlike anything observed in the last 150 years–have regularly occurred in the Indian subcontinent throughout the last 1,000 years. The new data indicate that the region's current rainfall predictability could give way to decades-long drought.
