Overview

• The South Asian summer monsoon provides 80% of annual rainfall to more than one billion people, sustaining agriculture and livelihoods.
• Climate models previously predicted a paradox of increasing monsoon rainfall despite weakening atmospheric circulation under global warming.
• A May 2025 study by He et al. analyzed Earth's past warm periods to explain this anomaly in monsoon projections.
• The research identified consistent monsoon patterns across past and future climates, enhancing the accuracy of forecasts under global warming.
• Improved predictions of monsoon behavior are vital for climate adaptation and resource management in South Asia.
