Who hasn't looked for the silver lining of this whole climate change fiasco? (Spring-like Januarys! Lucrative shipping passages! More cod in Greenland!) And now that always-optimistic bunch, surfers, are turning Alaska's crumbling glaciers from a frightening harbinger into the setting for perhaps the greatest extreme sport ever invented. Last week champion surfers Garrett McNamara and Kealii Mamala made history by being the first people to ride a glacial wave. After camping for weeks (and spending hours at a time bobbing in the frigid water), they caught the wave made by a 400-feet chunk of Child's Glacier crashing down and rode it for about a minute.
Garrett's conclusion? "I wouldn't recommend it for anyone. I won't be going back. This is not a new sport." Fun!—Abby Seiff
