|A branch of the Upsala Glacier.|
There are lots of videos of glaciers collapsing and causing waves. But a tourist has captured some rare footage of an iceberg tipping over while on a boat near the Upsala Glacier in Argentina.
The tourist has posted the video to YouTube where he writes:
"While we were passing by it with a catamaran, the huge berg lost part of itself (look at the ride 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...March 2012..."
The Upsala Glacier was once the largest in South America and is retreating at a rate of about 600 feet a year. Some scientists say the melting of Upsala is a result of other natural factors and is not primarily connected to climate change.
