　　Climate change is threatening to redraw the world's wine­producing map，and the effects are already being seen in earlier harvests and coarser（更为粗糙、劣质的）wines.

　　“The consequences of global warming are already being felt.Harvests are already coming 10 days earlier than before in almost all grape­growing regions，”said Bernard Seguin，the head of climate studies at France's INRA agricultural research institute.He was speaking at the opening of the Second International Congress on Wine and Climate Change.“Wine and wine­producing will change in a way that will depend on how we face global warming，”said Seguin.“If the temperature rises two or three degrees centigrade，we could manage to see Bordeaux remain as Bordeaux，Rioja as Rioja，Burgundy as Burgundy.But if it goes up five or six degrees，we must face up to huge problems，and the changes will be hard，”he said.

　　Grapes are damaged if they ripen too quickly，due to higher temperatures and a lack of rain.“When a grape matures more quickly，you get higher concentrations of sugar，lower acidity（酸性）and a higher PH level，”said Fernando Zamora of the oenology faculty（葡萄酒酿造学系）at the University of Tarragona in Spain.The result is coarser wines，with a higher alcohol level and lower acidity which can destroy the delicate flavor of good quality wines，he said.
