This article discusses how climate change will deleteriously impact the wine industry.
At first, global warming was a boon for wine production: Vines yielded more grapes, and those grapes ripened earlier, resulting in a crop that was richer and more pleasing. Most of the world’s wine grapes are grown in a band between the thirtieth and fiftieth parallels, with a significant concentration at the forty-fifth parallel north, halfway between the equator and the North Pole (Oregon, Bordeaux, the Rhone Valley and Provence, Central Otago in New Zealand, etc.). By 2050, many researchers expect those regions to be inhospitable to wine grapes, or at least to the varieties currently grown there; Pinot Noir will be impossible in Oregon, and Bordeaux will be better suited to Syrah, Cabernet Sauvignon, and Merlot. Some areas, such as mainland Australia, won’t be able to make wine at all.
