Why most wine production could be lost in the next 50 years

Dr. Lee Hannah, senior climate change researcher at Conservation International in California, predicted vast shifts in the global wine industry with the publication of his 2013 paper, “Climate change, wine, and conservation,” which included a series of predictive maps.

At the time, wine insiders disputed its only 30-year timeline, but a decade later, no one is refuting its claims. The paper reports that due to climate change, by 2050 many traditional wine regions across Europe, from the Mediterranean to the North Seas, will become less suitable for growing wine grapes, including the region of Champagne, and the prosperous countries of Spain, Portugal, France and Italy. , and German wine regions. The map (pictured) shows red areas, including most classic wine regions, that will become uninhabitable for grapes. Green areas will remain viable, and blue areas will open up new possibilities and emerging regions. Emerging regions of Canada, England, Scandinavia and China grow wine grapes.

Hannah continues that even amid massive and destructive droughts and fires across California, her famous wine regions, including Napa and Sonoma, will benefit from climate change for now. It won’t last long. Wine grapes only thrive in specific climatic circumstances and need warm, sunny days and cool nights to produce the best fruit, Climate Central. Grapes do not like the slightest fluctuations in temperature norms, water availability and humidity.
