A study published last month in the journal Proceedings of the National Academy of Sciences forecasts that temperature increases may trigger the loss of at least two thirds of Napa Valley’s grape output by 2050 with similar losses in wine producing regions in France. A team of nine researchers used 17 different climate models to gauge the coming effects of global warming on nine major wine producing regions. California’s wine region is expected to shrink by 70% with regions in France, Italy and the Mediterranean shrinking by 85%. If wine production is to continue in these areas it will have to be done with different varieties and using different techniques that will likely be more expensive.
