Climate change may not be good news for the Californian wine industry, according to a paper published in the open-access journal PNAS (Proceedings of the National Academy of Sciences of the United States of America). California is the UK's third largest source of wine after Australia (no 1) and France (no 2). An extract from the paper states:
‘…we estimate that potential premium winegrape production area in the conterminous United States could decline by up to 81% by the late 21st century.

‘…we estimate that potential premium winegrape production area in the conterminous United States could decline by up to 81% by the late 21st century.
While increases in heat accumulation will shift wine production to warmer climate varieties and/or lower-quality wines, and frost constraints will be reduced, increases in the frequency of extreme hot days (>35 degree C) in the growing season are projected to eliminate winegrape production in many areas of the United States.
Furthermore, grape and wine production will likely be restricted to a narrow West Coast region and the Northwest and Northeast, areas currently facing challenges related to excess moisture.’
