Multiyear measurements of ebullitive methane flux from three subarctic lakes [PDF]

, 2013
Ebullition (bubbling) from small lakes and ponds at high latitudes is an important yet unconstrained source of atmospheric methane (CH4). Small water bodies are most abundant in permanently frozen peatlands, and it is speculated that their emissions will

Twenty‐Three Years of Landslide Activity in the European Alps–Part 2: Investigating Triggers and the Impacts of Meteorological Change on Landslide Occurrences

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

Permafrost distribution and permafrost degradation in the polar regions

, 2018
Climate change is clearly impacting the state and distribution of permafrost in the polar regions. Gradual thawing through deepening of the seasonally active layer as well as rapid thawing through coastal erosion, thermokarst, and thaw slumping is intensifying.

Global Warming Amplifies the Risk of Uncertainties in Projections of Deepened Summer Thaw Depth Across Northern Hemisphere Zone

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract A warming climate endangered to destabilize the expansive permafrost zone and its summer thaw depth in the northern part of the earth. This climatic shift exacerbated the challenges associated with predicting future summer thaw depths, thereby escalating the associated risks.

Multiple thermophysical effects of aeolian sand cover on permafrost under climate warming and wetting

Geoderma
Permafrost degradation on the Tibetan Plateau (TP) poses serious risks to the environment and infrastructure. Permafrost changes are controlled by both climate changes and local factors, including climate warming, wetting, and aeolian desertification ...

Achieving Harmonized and Integrated Long‐Term Environmental Observation of Essential Ecosystem Variables ‐ The eLTER Framework of Standard Observations

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract The development of harmonized, standardized, and integrated environmental observation systems is a key challenge in Earth system science. Such capability is essential for advancing the interdisciplinary research needed to improve understanding of the Earth system and support global sustainability.

Discharge Regimes of North American High‐Latitude Rivers

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract Regimes of river discharge, characterized by the timing and magnitude of seasonal and stochastic flow variation, are changing in northern rivers due to warming climate. However, spatial heterogeneity in discharge regimes across high‐latitude regions has made it difficult to predict flows under accelerated warming.

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...
