If there were any climate-change doubters in the wine industry, it seems they are now as rare as a 1921 Château d'Yquem. As the third annual World Conference on Climate Change and Wine gets underway April 13-14 in Marbella, Spain, the debate seems to be settled, and a new evolution in mentalities is taking place. "I think the majority of the wine industry has acknowledged that there is a problem called climate change — the impacts are being observed in wine regions throughout the whole world," says Pancho Campo, Spain's first master of wine and the conference's organizer. "Now, the next step is we have to motivate them to start taking action."
