Scientists unequivocally believe that humans are causing the earth's temperature to rise. The global weather system has already gotten more unpredictable. And even insignificant climate changes can have dramatic effects on wine. In fact, by the end of the century, global warming may decrease the areas in the U.S. in which wine can be produced by 81%. Grape production in France doesn't look very promising either. However, grape production in England, being further to the north, is expected to benefit from global warming.

What about India? States like Himachel Pradesh which are slightly cooler may start producing better wines. It is left to be seen what impact this has on places like Nasik. As this LA Times article points out, in a not too distant future the best sparkling may not come from Champagne but from Surrey, England.
