The Juneau ice field in Alaska, containing over 1,000 glaciers, is melting faster than predicted, potentially reaching a tipping point soon, according to a study in Nature Communications. Ice loss accelerated rapidly after 2005, with area shrinkage rates five times faster from 2015-2019 compared to 1979-1990, and glacier volume loss doubling after 2010. The study indicates pervasive thinning and fragmentation since 2005, suggesting future glacier regrowth is unlikely. Lead author Bethan Davies highlights the vulnerability of flat, plateau icefields to accelerated melt due to climate warming.
