Scientists studying speleothems in Mawsmai Cave have uncovered evidence of monsoon intensity dating back 4,200 years, offering a new climate benchmark for the region.
Researchers examining mineral deposits inside Mawsmai Cave in Meghalaya have identified a continuous record of monsoon activity that stretches back roughly 4,200 years. Using uranium‑series dating techniques, the team established the age of the speleothem layers and linked variations in their composition to changes in rainfall intensity over millennia.
The findings suggest that the region experienced several distinct phases of stronger and weaker monsoon periods, aligning with broader South Asian climate shifts documented in other proxy records. This cave‑based archive provides a rare, high‑resolution glimpse into the pre‑instrumental era of the Indian subcontinent's monsoon system.
Experts say the new data will help refine climate models that predict future monsoon behavior, especially as the subcontinent faces growing climate‑related challenges. The study underscores the importance of Meghalaya's limestone caves as natural laboratories for reconstructing past environmental conditions.
