Wine grapes are about as sensitive as your head the morning after you've tied one on with a bottle of Bordeaux: They need just the right climate to thrive. And that climate, of course, is changing.
A new study published in the journal Proceedings of the National Academy of Sciences predicts the rapid decline of wine-growing regions from California to Australia -- quite the headache for the $290-billion-a-year global wine industry.
Researchers predict a two-thirds fall in production in the world's premier wine regions because of climate change. ...
The scientists used 17 different climate models to gauge the effects on nine major wine-producing areas. They used two different climate futures for 2050, one assuming a worst-case scenario with a 4.7C (8.5F) warming, the other a 2.5C increase.
Both forecast a radical re-ordering of the wine world. The most drastic decline was expected in Europe, where the scientists found a 85% decrease in production in Bordeaux, Rhone and Tuscany.
The future was also bleak for wine growing areas of Australia, with a 74% drop, and California, with a 70% fall
