Global Warming to hurt traditional wine making regions

According to a new study by economists Orley Ashenfelter of Princeton University and Karl Storchmann of Whitman College, vineyards are getting warmer due to solar radiation and global warming. Vineyards to the north (at the top end of the latitude wine belt (50 degrees) such as those in Germany, England and Sweden are set to produce better wines while the ones in the south as in Southern France, Italy and Spain will suffer.

How does this affect India? The warmer climates will probably negatively affect grape production given our latitude. Indian farmers maybe forced to find new, cooler locations in other parts of India as the world gets warmer.
