    Europe is, after Asia, the second largest producer of wheat in the world, and provides
    the largest share of barley. Wheat (and to a similar extent, barley) production in Europe increased
    by more than 6-fold during the 20th century. During the first half of the 20th century, this was
    driven by expanding the harvested area. This was followed, from the mid-20th century, by a massive
    increase in productivity that in many regions has stalled since 2000. However, it remains
    unclear what role climatic factors have played in these changes. Understanding the net impact of
    climatic trends over the past century would also aid in our understanding of the potential impact
    of future climate changes and in assessments of the potential for adaptation across Europe. In this
    study, we compiled information from several sources on winter wheat and spring barley yields and
    climatological data from 12 countries/regions covering the period from 1901−2012. The studied
    area includes the majority of climatic regions in which wheat and barley are grown (from central
    Italy to Finland). We hypothesized that changes in climatic conditions have led to measurable
    shifts in climate−yield relationships over the past 112 yr, and that presently grown wheat and barley
    show a more pronounced response to adverse weather conditions compared to crops from the
    early 20th century. The results confirm that climate−yield relationships have changed significantly
    over the period studied, and that in some regions, different predictors have had a greater effect on
    yields in recent times (between 1991 and 2012) than in previous decades. It is likely that changes
    in the climate−yield relationship at the local level might be more pronounced than those across
    the relatively large regions used in this study, as the latter represents aggregations of yields from
    various agroclimatic and pedoclimatic conditions that may show opposing trends.
