The authors of this letter to Nature Climate Change link vulnerabilities in food production to climate change as well as air pollution. They also note that while these issues are understood as threats to global food security, our detailed understanding of interactions between climate and ozone pollution is limited, as are their independing effects on different crops and different regions. Their letter presents an integrated analysis of climate and ozone trends from 2000-2050.
