Glacier Calving Moment Reshapes Climate Truth for Skeptic Turned Believer

Photographer James Balog’s Greenland footage captured the largest glacier calving event ever filmed, a watershed moment that helped shift him from climate-skeptic to climate-believer. The footage shows a chunk of ice the size of lower Manhattan breaking off and entering the sea, an unprecedented geological event caught on camera during the Extreme Ice Survey. Balog’s 15-year project produced over 1.5 million images and a follow-up documentary, Chasing Time, documenting the immediacy of climate change for future audiences.

Ten-kilometer fiber-optic cable reveals 56,000 glacier calving events beneath Greenland’s fjords

Researchers laid a 10-km fiber-optic cable on the seafloor near a Greenland glacier and used distributed acoustic and temperature sensing to monitor calving. Over three weeks the system recorded more than 56,000 iceberg detachments, uncovering the full calving sequence from internal cracking to detachment and underwater waves, and revealing how iceberg motion drives water circulation and heat distribution. This continuously sensing approach provides high-resolution insights into glacier dynamics and ocean interactions that aren’t captured by surface observations.
