Photographer James Balog filmed a documentary titled CHASING ICE where he literally filmed ice melting. Its a lot more exciting (and scary) than you think! "Pieces of ice were shooting up out of the ocean 600 feet and falling." We're talking about million year-old glacial chucks the size of skyscrapers just about leaping up out of the ocean. Watch this incredible video capturing a HUGE chunk of the planet's surface just dissolving! This is apparently the largest glacial caving ever caught on film.
