Abstract
Abstract
Climate warming is one of the major threats to global livestock production. However, the impact of climate warming on livestock meat yield at global scale is rarely investigated. In this study, we present a statistical evidence from country-level cattle meat yield that the response of global cattle meat yield to climate warming is invert-U quadratic nonlinear, which is more obvious in the grassland-based livestock system. Moreover, the nonlinear response determines that climate warming creates unequal burden between high- and low- income countries due to the divergent baseline temperature condition. Future climate warming aggravates these unequal burdens, with the most pronounced effects observed under SSP585. Our results highlight the need for focusing on the global food security under climate change from livestock meat production.
