Scientists said that by the middle of this century, average temperatures will rise just enough to pose a hazard to the making of classic wines.

Does this mean that cabernet sauvignon will soon be planted in Wisconsin; chardonnay in Alaska; and that Napa is destined to become a tropical housing paradise for San Francisco commuters?

Now, if I tell you this story is from the Napa Valley Register, can you guess how they answer that last question?

I'm tellin' ya those 2005 Bordeaux's are looking better every week.

Update: I love open-access science! Everything funded by the taxpayer should be available to the folks who write the check.

Here's the paper from the Proceedings of the National Academy of Science:
