Yahoo! points us to this incredible video of an iceberg tipping over, captured by tourists on a boat near the Upsala Glacier in Argentina. Unfortunately, the awe of the video is offset by the understanding that this might have happened due to global warming (some scientists posit that the melting Upsala Glacier is a result of natural factors, however).
Posted on YouTube, the tourist describes the moment: “While we were passing by it with a catamaran, the huge berg lost a part of itself (look at the right side sinking) and then flipped over with a huge roar. In the process of melting this happens all the time, but it is seldom that it is captured on video WHEN it happens…”
The BBC reports that the Upsala Glacier, which was once the largest in South America, has been melting for years, and is retreating at a rate of about 600 feet per year.
