Assessing climate risks to UK agriculture

In January 2012, the first Climate Change Risk Assessment (CCRA) report was presented to the UK government to inform national adaptation policy. Regarding the agricultural sector, we and our colleagues used a risk-metric approach to assess consequences for crop yield. Writing in Nature Climate Change, Semenov et al. present a critique on the crop yield metric used in our analysis. Although we do not refute the scientific evidence presented, we do question its purpose. (Correspondence)
