LOS ALAMOS, N.M., Oct. 17, 2018–A new collaborative study has investigated Arctic shrub-snow interactions to obtain a better understanding of the far north’s tundra and vast permafrost system. Incorporating extensive in situ observations, Los Alamos National Laboratory scientists tested their theories with a novel 3D computer model and confirmed that shrubs can lead to significant […]

Rapid Ice-Wedge Melting Accelerates Permafrost Decline

By Nancy Ambrosiano | Los Alamos National Laboratory on Mar 17, 2016 Featured, The Arctic and Alaska Science

LOS ALAMOS, N.M.—A new study of permafrost has found that the ice wedges forming the prevalent honeycomb pattern across the tundra appear to be melting rapidly across the Arctic, changing the hydrology of the region and accelerating the release of greenhouse gases with major implications for global warming. While the gradual warming of permafrost has […]
