TL;DR
Jakobshavn Glacier retreating 30-40 meters per day (2010s)
Documents Jakobshavn Glacier as the fastest glacier on Earth, retreating 30-40 meters per day during the 2010s. Provides an extreme example of positive feedback calving that demonstrates how once initiated, these processes can accelerate dramatically and won't stabilize for decades.
Key Findings from Joughin & al. (2012)
- Jakobshavn Glacier retreating 30-40 meters per day (2010s)
