Alaska's Juneau Icefield Melting Nearly Five Times Faster Than in the 1980s
New research reveals accelerated glacier loss, with potential irreversible tipping points looming sooner than expected.
- The Juneau Icefield's melt rate has surged dramatically since 2010, losing ice at 5.91 km³ per year between 2010-2020.
- Glacier shrinkage rates from 2015-2019 were five times faster compared to 1948-1979.
- Researchers warn that the flat, plateau-like structure of Alaskan icefields makes them particularly vulnerable to accelerated melting.
- The study utilized historical records, aerial photographs, and satellite imagery to track changes dating back to 1770.
- Experts suggest current glacier melt projections may underestimate future ice loss.
