Geological records can help scientists understand future Indian monsoons
Anil Kumar Gupta said geological history can help scientists understand future monsoon behaviour at a research institute celebration in India.
He said natural climate records preserve evidence of past rainfall and temperature in places such as marine sediments, lake deposits, caves, tree rings and ice cores.
Scientists can use these records, with accurate dating, to reconstruct long-term climate changes.
Ancient geological changes helped shape the Indian monsoon, including the collision of the Indian and Asian plates and the rise of the Himalaya-Tibetan Plateau.
Gupta also highlighted how El Niño and the Indian Ocean Dipole influence the summer monsoon.
Understanding these past changes and climate interactions can help researchers assess long-term patterns, but no specific next step was announced.
Anil Kumar Gupta said geological records can help scientists understand long-term changes in the Indian monsoon and improve understanding of future climate variability.
He spoke at the 66th Foundation Day celebrations of the CSIR-National Geophysical Research Institute.
Gupta said records in marine sediments, lake deposits, cave formations, tree rings and ice cores can reveal past climate conditions.
He said combining multiple climate indicators with accurate dating is essential for reliable climate reconstruction.
He linked the monsoon’s long-term evolution to geological events including the collision of the Indian and Asian tectonic plates and the uplift of the Himalaya-Tibetan Plateau region.
