A Modeling Toolbox for Permafrost Landscapes
Eos, 2018 A new resource makes it easier for researchers to explore predictions of how melting permafrost might affect carbon release, wetlands, and river deltas as they evolve and other interacting effects.

Geosciences, 2023 Rapid Arctic warming is expected to result in widespread permafrost degradation. However, observations show that site-specific conditions (vegetation and soils) may offset the reaction of permafrost to climate change.

Beaded streams of Arctic permafrost landscapes [PDF]
, 2014 Abstract. Beaded streams are widespread in permafrost regions and are considered a common thermokarst landform. However, little is known about their distribution, how and under what conditions they form, and how their intriguing morphology translates to ecosystem functions and habitat. Here we report on a Circum-Arctic inventory of beaded streams and a

Enhanced CO2 emissions driven by flooding in a simulation of palsa degradation [PDF]
BiogeosciencesClimate change is predicted to put most of the permafrost habitats in the discontinuous zone at risk of disappearing within the next few decades. On a decadal scale, abrupt permafrost thaw may result in larger C losses than gradual permafrost thaw, but ...

Complex Vulnerabilities of the Water and Aquatic Carbon Cycles to Permafrost Thaw
Frontiers in Climate, 2021 The spatial distribution and depth of permafrost are changing in response to warming and landscape disturbance across northern Arctic and boreal regions. This alters the infiltration, flow, surface and subsurface distribution, and hydrologic connectivity

Mapping Mountain Permafrost Landscapes in Siberia Using Landsat Thermal Imagery
Geosciences, 2018 Intensive development of South Yakutia, a mountainous area in the Russian sporadic permafrost zone, must be founded on knowledge about regional permafrost conditions. New permafrost maps for mountainous areas in South Yakutia (the Elkon Mountains and the

Scaling-up permafrost thermal measurements in western Alaska using an ecotype approach [PDF]
The Cryosphere, 2016 Permafrost temperatures are increasing in Alaska due to climate change and in some cases permafrost is thawing and degrading. In areas where degradation has already occurred the effects can be dramatic, resulting in changing ecosystems, carbon release,

Environmental Research Letters, 2023 Northwestern Canada is currently warming nearly four times faster than the global average, driving accelerated permafrost thaw and changes to ecosystem vegetation, hydrology and landscape structure across the landscape.

Estimating lichen biomass in forests and peatlands of northwestern Canada in a changing climate
Arctic, Antarctic, and Alpine Research, 2022 Climate warming in the North could lead to lichen decline within critical woodland caribou habitat. We used repeat measurements of sixty-nine plots over ten years (2007–2008 and 2017–2018) to assess lichen biomass changes under a warming climate along a ...
