Temperature increase reduces global yields of major crops in four independent estimates ($)

Although future negative impacts on crop yields expected from rising temperature are well known to plant scientists, there are still some members of the broader public that need to be made aware of this problem. Zhao et al. combined four different methods of assessing the impact of increasing temperatures on yields of wheat, rice, maize, and soybean across global and regional areas. Their results will be useful to “develop targeted adaptive strategies to feed a burgeoning world population.” Proc. Natl. Acad. Sci. USA  10.1073/pnas.1701762114
