science π Monsoon code cracked; fishing faces big threat π£
Scientists have resolved a puzzle regarding the South Asian summer monsoon cycle using geological records. This breakthrough came from a global team including the University of Sussex, Ninjing University, and Ohio State University. The study found that rising temperatures in Southern Africa reduce Arabian Sea upwelling, impacting marine productivity. This mechanism shows that monsoon rainfall and sea upwelling are driven by different hemispheric solar forcings. Future climate risks must consider this broader, coupled system for livelihoods across the region.
