The impact of climate change on some of the best-known wine areas

Thanks to climate change, Oregon now produces some of the finest pinot noirs in the country. But rising temperatures could have a devastating impact on California’s Napa Valley. When researchers looked at where climate will be suitable for quality wine grapes by 2050, there were significant shifts in California — toward the coast and north toward Oregon. They estimated that by then, there could be 60 percent less land in California suitable for wine grapes. Al Jazeera America travels to Oregon and Napa to see how wine makers hope to adapt as temperatures rise.
