New warning for wine on climate threat

More than half the world's vineyards could be unviable if the planet warms by two degrees Celcius, but switching grape varieties may help, says a new study.

Swapping grape varieties can significantly offset damage that would be inflicted on some wine regions by higher temperatures linked to climate change, says a study published in the Proceedings of the National Academy of Sciences (PNAS) this month.


Up to 56% of current wine growing land may no longer be suitable for vineyards if the planet warms by two degrees Celcius - the upper limit set by the Paris Climate Agreement - says the study.


That figure rises to 85% if warming hits four degrees, says the study, which used historical growing season data for 11 grape varieties, including Cabernet Sauvignon, Pinot Noir and Chardonnay, to create its model.


It is one of the starkest warnings so far about the size of the climate challenge facing vineyards.


But, it says there’s still time to adapt and that switching grape varieties could reduce losses by more than half in some cases.
