Ancient pollen hidden below lake tells the story of a stronger monsoon
- Palynology-based palaeoclimate study by Birbal Sahni Institute of Palaeosciences (BSIP), Lucknow reconstructed a ~2,500-year vegetation–climate record from Raja Rani Lake, Korba district, Chhattisgarh, in India's Core Monsoon Zone (CMZ).
- Evidence indicates intense rainfall and stronger Indian Summer Monsoon (ISM) between 1060–1725 CE in central India — relevant for GS-I (geography/climatology) and GS-III (science & climate change).
