The Earth's Greatest Porous Media

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Pluriversal Terrain: Rethinking More‐Than‐Human Borders in the Himalaya

Area, Volume 58, Issue 4, December 2026.
ABSTRACT In the Himalaya, border‐making, as a key territorial practice, is entangled with terrain, necessitating a more‐than‐human understanding of borders. The Himalayan terrain actively shapes geopolitical borderlands, while also being understood within certain Indigenous ontologies as the abode of deities whose power is revered and invoked through ...

Ruins in the Field: Materiality, Spectres and Pluritemporal Encounters of the Oxford University Arctic Expedition

Transactions of the Institute of British Geographers, Volume 51, Issue 4, December 2026.
Short Abstract This paper contributes to conceptual debates on ruins by generating novel insights into how encounters with the haunted materialities of ruins in the field inform (post)colonial trajectories of exploration. Empirically, it examines how material and spectral traces of past lives in the field, alongside play with categories of absence and ...

How the River Network Shapes Spatiotemporal Drought Behavior Across Europe

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding spatial drought relationships is important for effective drought relief. The river network—that is, the system of rivers, channels, lakes, and reservoirs within a river basin—influences spatial streamflow drought connectivity and modulates drought characteristics.
