Grape growing temperatures will migrate northward, and traditional winemaking areas (such as France, Italy, and California) could see declining yield and quality. By 2050, the area suitable for cultivating wine grapes will decrease 25% to 73%. Many winemakers are already making plans for changing the variety of grape they cultivate within the next few decades to suit the changing climate. Meanwhile, previously vineyard-sparse areas such as Great Britain may become major wine centers.
