The authors in “Response of corn markets to climate volatility under alternative energy futures” address the concern regarding food insecurity. Climate change might aggravate the issue by reducing grain yields in the coming decades. However, examples in the United States are used, citing intensification of hot weather conditions in the corn-growing parts of the country. This leads to volatility of corn prices, but ultimately has little impact on food prices. This suggests an important interaction between energy policies, energy-agriculture linkages, and climate change.
