Our publications come from cross-disciplinary research that relies on a team of ecologists, climatologists, crop modelers, and experts in winegrape diversity and viticulture. Each publication takes years of work.
In the papers below, learn more about the importance of wine variety diversity in mitigating the effects climate change may bring to the wine industry.
Figure 1. Global maps of winegrowing. (A) Current winegrowing regions (B) Modeled predictions of cultivar diversity (total number of varieties) under our 0 ◦C reference scenario—all colored pixels show areas predicted as climatically suitable (Calculating Climatic Suitability). (C–E) Predicted effects of climate change on cultivar diversity and distribution under 2 ◦C warming (C), 4 ◦C warming (D), and cultivar turnover.

Figure 1. As tempertures across the globe have risen significantly since the early 1980s, harvest times have shifted earlier. Here we show (left) global temperature anomalies (the change in global surface temperature relative to 1951-1980 average temperatures) and harvest times (relative to 31 August) averaged across France, and (right) for the Bordeaux region. Temperature anomalies data from NASA-GISS and BEST; harvest data from Daux et al. (2012), Cook and Wolkovich (2016). Note that harvest data ends in 2007, while we show climate data through 2017.
