Glacier Calving: Largest Ever Filmed
1 Sep
Summary
- Massive Greenland glacier chunk calved off, filmed by photographer.
- The collapse was the largest glacial calving event ever recorded.
- Photographer James Balog, once skeptical, now documents climate change.

A breathtaking natural event unfolded in Greenland as photographer James Balog and his crew captured the largest glacier calving ever filmed. For over an hour, they observed a colossal section of ice, estimated to be the size of lower Manhattan and significantly taller, detach and melt into the sea. This dramatic spectacle serves as potent visual evidence of climate change.
Balog, who had previously expressed skepticism about human-induced climate change since the 1980s, changed his views after a 2005 expedition to the Arctic. Witnessing tangible evidence of global warming preserved in ice cores from Greenland and Antarctica, he recognized the severity and immediacy of the crisis. His extensive Extreme Ice Survey, which concluded in 2022, amassed over 1.5 million images documenting environmental changes. A recent documentary, "Chasing Time," revisits Balog's work, highlighting his commitment to recording these critical shifts for future generations.
