Untapped crop data from Africa predicts corn peril if temperatures rise

A team led by David Lobell has found a valuable, untapped resource in historical data from crop yield trials conducted across sub-Saharan Africa. Combined with weather records, they show that yield losses would occur across 65 percent of maize-growing areas from a temperature rise of a single degree Celsius, even with sufficient water. Data from yield tests in other regions of the world could help predict changes in crop yields from climate change.
