“In some ways, wine is like the canary in the coal mine for climate change impacts on agriculture, because these grapes are so climate-sensitive,” said study co-author Benjamin Cook of Columbia University’s Lamont-Doherty Earth Observatory.
Wine grapes are extremely sensitive to the changes in temperature and season that come with climate change.But there is hope: By switching some of the varieties of wine around, losses could be reduced.Many of the world's prime wine-growing regions could shrink dramatically due to human-caused climate change, aThis is because wine grapes are extremely sensitive to the changes in temperature and season that come with climate change.
And with 7.2 degrees of warming, 85 percent of those lands would no longer be able to produce good wines. Wine-growing regions that are already warm now – such as Italy, Spain, and Australia – will see the largest losses as the planet heats up. But the scientists say that cooler wine-growing regions in countries like Germany, New Zealand and the U.S. Pacific Northwest could be relatively unscathed.Still, overall, study authors said that losses were unavoidable in both warming scenarios, due to shifting temperatures and seasonal changes that would affect conditions while the varieties were ripening.
“Conversations in Europe have already begun about new legislation to make it easier for major regions to change the varieties they grow,” said study co-author Elizabeth Wolkovich of the University of British Columbia in Vancouver.
