923. Sour grapes

But there's lots of cheap acreage in Greenland now. Stop whining and get out your checkbook.

L.A. Times:
Global Warming May Shrink Vineyards: A climate projection shows 'enormous losses' in the state's prime wine regions this century.

Global warming could wither many premium vineyards in California and across the nation by the end of the century, according to a new computerized climate projection released Monday.

A predicted rise in the number of days hotter than 95 degrees during the growing season could sharply reduce the amount of areas suitable for vintage wine-grape production, an international team of scientists concluded in the journal Proceedings of the National Academy of Sciences.

Marginal vineyards nationwide might be eliminated and those capable of producing the most expensive premium wines may be reduced by half, the researchers reported. Although wine is produced in 48 states, California's $16.5-billion industry, with more than 500,000 acres of vineyards, accounts for almost 90% of the nation's wine grapes.

"We found that at elevated greenhouse gas concentrations, the frequency of extremely hot days increases to the point where it is impossible to grow premium wine grapes in many areas of the country," said Noah Diffenbaugh, one of the study's researchers at Purdue University who studies the impact of climate change.

"Certainly, the Napa Valley, the Sonoma Valley and the Santa Barbara area all exhibit enormous losses of production in the future climate," Diffenbaugh said.

and the rest....
