Power players in the U.S. are finally sitting up and taking note of climate change. But don’t get hopeful just yet. They’re not leaping to figure out how to retool our industrial system and stave off disaster. Rather, they’re calculating which islands will make the best vacation getaways for the rich and famous in a globally warmed world.

Yes, The Wall Street Journal has helpfully published “The Global Climate-Change Island Guide” [subscribers only, alas], informed by the new “Dow Jones Island Index” [PDF; should work even for non-subscribers], which analyzes “12 factors that reflect a range of environmental risks that islands and island tourists face.”

Of 40 islands examined, the top ranked for your continued vacation pleasure is Prince Edward Island off Canada’s east coast. Of course, the average temperature in December is 24 degrees Fahrenheit, but maybe a little more warming will nudge that number up to a more comfortable range.

Elites will be more happy to see that Martha’s Vineyard ranks second on the list. Also scoring reasonably well: the Florida Keys, Grand Cayman Island, and Crete.

Grist thanks its sponsors. Become one.

Steer clear of Sri Lanka, though, which bottoms out the list. Other islands you might want to avoid: the Dominican Republic, Cuba, and Fiji.
