If someone told me the local iceberg was collapsing, I would be out there with the crowd watching it. This was recorded in Argentina. The show gets more intense toward the end. ~via Ursi’s Blog
Update: I did a little digging, and this has been identified as the Perito Moreno Glacier {wiki} in Los Glaciares National Park. The breakup is a natural phenomena that can be forecasted, but it’s not regular, happening every one to ten years. It's a big tourist attraction.

Use your brain
If there are substantial winter snowfalls further up the glacier, it thickens at the ends, and pieces drop off. A natural phenomenon.
People who blame this on global warming are being intellectually lazy, and probably should not be allowed out without a minder.
