A new study published in Nature Reviews Earth and Environment suggests that climate change could significantly impact traditional wine-growing regions, potentially leading to a decline in French and Italian wine production while creating favorable conditions for British vineyards.
Researchers analyzed the effects of rising temperatures, drought, and changes in pests and diseases on global wine regions. Their findings indicate a substantial risk that 49% to 70% of current wine-producing regions could become economically unviable by 2100, depending on the severity of global warming.
However, the study also highlights potential benefits for regions previously considered unsuitable for wine production. As temperatures rise, areas at higher latitudes and altitudes, including southern parts of Great Britain, could see improved conditions for viticulture.
The study emphasizes the importance of limiting global warming to within 2 degrees Celsius, as outlined in the Paris Agreement. If warming exceeds this limit, most Mediterranean wine regions, including parts of Spain, Italy, and Greece, could become unsuitable for wine production by the end of the century.
While France may not be the most vulnerable country, the study suggests that even traditional wine-producing regions will need to adapt by using more resilient grape varieties and potentially reconsidering irrigation practices.
This research highlights the significant impact climate change could have on the global wine industry, potentially leading to a shift in production from established regions to new and emerging areas like Great Britain.
It is important to note that the study focuses on the potential impact on “quality wine at economically viable yields.” Wine production may still be possible in many regions, but the quality and economic viability may be compromised.
