It is found that the impact of large-scale climate variability can affect crop yields in different regions of the world at the same time. This finding overturns one of the core concepts of the global agricultural system: There is no correlation between crop failures among the grain producing areas which are geographically distant from each other.

Typhoon storm in China, flood in South Asia and hurricane in North America…The extreme weather and climate events surged the global major grain producing areas in the first eight months of 2019. A recent research has found that the impact of large-scale climate variability can affect crop yields in different regions of the world at the same time, posing great challenges to food security. The research was achieved by the experts from International Research Institute for Climate and Society (IRICS), Columbia University, USA, International Food Policy Research Institute (IFPRI) and Macro Agriculture Research Institute (MARI), Huazhong Agricultural University (HZAU). Recently, the relevant academic achievement has been published on Science Advances as a cover story. This research also attracts the attention from academia because it overturns one of the core concepts of the global agricultural system: There is no correlation between crop failures among the grain producing areas which are geographically distant from each other.
