Wheat is the third most worldwide cultivated cereal and the first one in Europe which represent 24% of the global production1,2. Global warming is predicted to significantly impact its production, slightly enhancing the yield in northern Europe but vastly increasing its variability3, 4.
These predictions are based on models fitted on the actual meteorological conditions. In this study, by using an Ecotron, a common wheat crop was submitted to two meteorological conditions, respectively representative of the present and of the future climate around the end of 21th century of western Europe under RCP 8.5. The aim of this experiment was to test the validity of validity of those claims.
