Comment on Lobell et al "Climate Trends and Global Crop Production Since 1980"

Abstract

Lobel et al (ScienceXpress) analysed changes in global yields which can be attributed to climate change trend, and reported a 5.5% decline in global wheat production since 1980. We have failed to confirm these results using a process-based crop model, which showed no decline in wheat yield since the 1950s at two European sites. The Lobel et al conclusions are not valid due to the limitations of the regression analysis used.
