First coffee, then chocolate. Now, researchers predict that climate change will affect another delicacy: wine. Washington State will overtake Northern California as the most diversified wine production region in the western United States by 2100, according to data presented by scientists at the fall meeting of the American Geophysical Society.

The two most famous wines in these regions, Cabernet Sauvignon and Pinot Noir, may have to "settle" elsewhere because the grapes will grow in conditions that are impossible to stay normal after 80 years. To generate their predictions, the researchers mapped the diversity of grapes grown in major wine-growing regions in the United States, and then through the high-emission "business as usual" scenario of the Intergovernmental Panel on Climate change, a model of future climate change is established. The "business as usual" scenario predicts that the global temperature will increase by 2.6℃ ~ 4.8℃ by 2100.

The data show that at the same stage, the number of wine grape species growing in Napa and other parts of California will decline from dozens to less than 10, while northern Washington and British Columbia will experience an explosive increase in the number of plantable grape varieties.

The data show that European grape-growing areas are also moving northward. However, not all hope is being lost: as grape varieties mature at different rates and grow at different temperatures and elevations, the researchers believe that expanding wine production areas to accommodate more grape varieties will help regional producers survive.
