Melting of Alaskan glaciers accelerating faster than previously thought
Melting of Alaskan glaciers accelerating faster than previously thought
Melting of glaciers in a major Alaskan icefield has accelerated and could reach an irreversible tipping point earlier than previously thought. The research found that glacier loss on Juneau Icefield, which straddles the boundary between Alaska and British Columbia, Canada, has increased dramatically since 2010. The team looked at records going back to 1770 and identified three distinct periods in how icefield volume changed. In particular, they found that icefield-wide, rates of glacier area shrinkage were five times faster from 2015-2019 relative to 1948-1979. The research team say that current published projections for the Juneau icefield may need to be updated to reflect the processes detailed in this latest study.
