Threat to future global food security from climate change and ozone air pollution
Future food production is highly vulnerable to both climate change and air pollution with implications for global food security. Climate change adaptation and ozone regulation have been identified as important strategies to safeguard food production5,6, but little is known about how climate and ozone pollution interact to affect agriculture, nor the relative eectiveness of these two strategies for different crops and regions. Here we present an integrated analysis of the individual and combined eects of 2000–2050 climate change and ozone trends on the production of four major crops (wheat, rice, maize and soybean)worldwide based on historical observations and model projections, specifically accounting for ozone–temperature co-variation.
