Reply to Meerburg et al: Growing Areas in Brazil and the United States with Similar Exposure to Extreme Heat Have Similar Yields - Appendix

Abstract

In a letter to the editor of the Proceedings of the National Academy of Sciences, Meerburg et al. argue that the predicted yield decreases from climate change in the United States in our earlier study are too pessimistic. They raise two major concerns: First, the authors argue that farmers in Brazil have higher yields even though "exposure to temperatures above the threshold values is far greater than in the US." Second, the authors argue that yields in the United States have been trending upward and are predicted to do so in the future. We provide additional information of our reply in this appendix.
