Scientists have identified a hidden rainfall pattern that could reshape global farming. Research shows crops suffer greater drought stress when rain comes mainly from land rather than oceans. The findings highlight rising risks in the U.S. Midwest and East Africa and suggest that forest conservation and better land management could help protect rainfall and food secur…Scientists have identified a hidden rainfall pattern that could reshape global farming.
