Study: Climate change threatens global supply of wine

News

(CNN) – A new study said climate change is threatening the global supply of wine. It found if the global temperature rises by 3.6 degrees Fahrenheit in the next 80 years, wine regions could shrink by up to 56%.

If there’s a rise of 7.2 degrees, 85% of those regions would be ruined. The massive losses would likely create a global shortage of wine, which would drive up prices.

One of the study’s co-authors said it boils down to grapes being sensitive to temperature change. Places like Italy, Spain and Australia could be the hardest hit.

Researchers focused on 11 grape varieties out of the 1,100 or so that exist. The international team of researchers said switching grape varieties or quantities could help cut those losses.

The study was published on Monday in “Proceedings of the National Academy of Sciences.”
