About The Cover
ONLINE COVER While past studies have demonstrated that global crop production stability is critical for food security, few studies have informed what factors force globally synchronous crop failures. Here, Anderson et al. quantify how modes of climate variability—the El Niño Southern Oscillation (ENSO), the Indian Ocean Dipole, tropical Atlantic variability (TAV) and the North Atlantic Oscillation (NAO)—contribute to varied yields of maize, soybean and wheat production around the world. While all of these climate modes can affect crop production, only ENSO can force globally synchronous crop failures, the authors find. The results are relevant to monitoring the risk factors that lead to such failures in the present climate and for understanding how they may change in a future climate.
