Today's top wine-producing regions from Chile to Tuscany could see their suitable growing area reduced by as much as 20 to 70 percent by the year 2050, the study suggests.

That means some growers will likely adjust by planting new vines in previously undisturbed ecosystems at higher latitudes or higher elevations—displacing the plant and animal species currently residing there.

“This can lead to serious impacts on wildlife habitat as new areas become suitable for wine production and open up to planting,” Hannah said.

Making matters worse is the intersection between tasty wine territory and prime habitat. Some of the top terrain for wine production is located in Mediterranean climate regions around the world boasting warm,
