Overview

• Study shows glacier melt rate in Juneau Icefield has quintupled since mid-20th century.
• Over 100 glaciers have disappeared from the icefield since 1770, with all remaining glaciers receding.
• Scientists warn that current models may underestimate future glacier melt and sea-level rise.
• Feedback loops from melting ice could prevent future glacier regrowth, leading to irreversible loss.
• Alaska's glaciers are the largest regional contributors to global sea-level rise.
