Science:北半球酿酒葡萄种植区正在北移

摘要 : 近日,科学家在美国地球物理学会秋季会议上展示的数据表明,气候变化会影响葡萄酒的生产,北半球酿酒葡萄种植区正在北移。到2100年,华盛顿州将取代北加州成为美国西部葡萄酒生产最多元化的地区。

近日,科学家在美国地球物理学会秋季会议上展示的数据表明,气候变化会影响葡萄酒的生产,北半球酿酒葡萄种植区正在北移。到2100年,华盛顿州将取代北加州成为美国西部葡萄酒生产最多元化的地区。

目前在这些地区最著名的两种葡萄酒——赤霞珠和黑比诺,可能不得不到其他地方“定居”,因为80年后这些葡萄会在不可能保持正常状态的条件下生长。为生成他们的预测,研究人员绘制了在美国各个主要葡萄酒产区生长的葡萄多样性地图,然后通过政府间气候变化专门委员会的高排放量“一切照旧”情形,建立了未来气候变化模型。“一切照旧”情形预测,到2100年全球气温将增加2.6℃~4.8℃。

数据显示,在同一阶段,生长于纳帕和加州其他地区的酿酒葡萄种类会从几十种下降到不足10种,而华盛顿北部和加拿大不列颠哥伦比亚省将经历可种植葡萄种类的爆发式增加。

数据表明,欧洲葡萄种植区也在向北移动。不过,所有的希望并非都在失去:由于各葡萄品种以不同的速度成熟,并且在不同的温度和海拔生长,研究人员认为,现在扩展葡萄酒产区以适应更多的葡萄品种,将有助于地区生产商幸免于难。

原文摘要:AN FRANCISCO, CALIFORNIA—First it was coffee, then chocolate. Now, researchers are predicting that climate change could shake up yet another gastronomic delicacy: wine. Data presented today at the fall meeting of the American Geophysical unio suggest that by 2100,Washington state could unseat Northern California as the most diverse wine-producing region in the western United States. And two of the most prominent wines in these regions right now—cabernet sauvignon and pinot noir—may have to take up residence elsewher. That’s because these grapes thrive in conditions unlikely to be the norm 80 years from now. To generate their predictions, the researchers mapped grape varieties grown in each of the country’s major wine-producing regions and then modeled future climate shifts using the Intergovernmental Panel on Climate Change’s high-emissions business-as-usual scenario, which has global temperatures jumping between 2.6°C and 4.8°C by the year 2100. In that same time period, according to the data, the number of wine grape varieties that can be grown in Napa and other California regions could dro from a few dozen to less than 10, while areas in northern Washington and British Columbia could see an explosion in cultivable grape varieties. The data suggest that wine-growing regions in Europe will shift northward as well. But all is not lost: Because grape varieties mature at varying rates and thrive at different temperatures and altitudes, the researchers suggest that expanding wine regions now to accommodate more varieties could help regional producers survive.
