Accelerating Glacier Melt in Alaska Signals Irreversible Changes

New research reveals that Alaska's Juneau Icefield is losing ice at an unprecedented rate, potentially crossing a critical tipping point.

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.
