Scientists issued a dire report in 2006 that said rising temperatures could render Napa Valley in California unsuitable for growing several types of premium grapes [source: Berg].

A more recent study, released in July 2011 by scientists at Stanford University, suggested that farmers will still be able to grow the grapes, but not in California. The study, which assumes an increase in temperature of 2 degrees Fahrenheit (-16.7 degrees Celsius) in the next 30 years, suggests that the growing of pinot noir and cabernet sauvignon grapes could shift to the Willamette Valley in Oregon and the Walla Walla Valley in Washington [source: Berg].

The growers need a temperature of about 68 degrees Fahrenheit (20 degrees Celsius) for the most delicate grapes. In this latest study, they found that we won't lose the wines, but that they may no longer be the crown jewels in the offerings of California growers.
