How much do climate fluctuations matter for global crop yields?

The El Niño-Southern Oscillation has been responsible for widespread, simultaneous crop failures in recent history, according to a new study. This finding runs counter to a central pillar of the global agriculture system, which assumes that crop failures in geographically distant breadbasket regions such as the United States, China and Argentina are unrelated. The results also underscore the potential opportunity to manage such climate risks, which can be predicted using seasonal climate forecasts.
