Climate change is not just resulting in a steady increase in temperatures, but also in an increased frequency and severity of extreme climatic events, like droughts, heat waves, and floods. These extreme conditions are particularly damaging for agriculture. Climate variability is responsible for at least 30% of the annual fluctuations in worldwide agricultural yield. Under “normal” climatic conditions, the global food system can compensate for local crop losses through grain storage and trade. However, it is doubtful whether the current system is resilient to more extreme climatic conditions.
