Constraints on Past CO2 and Climate Sensitivity From Global Temperature and Sea Level Reconstructions Across the Plio‐Pleistocene

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In contrast to previous approaches, new reconstructions of changes in global mean surface temperature and global mean sea level (GMSL) include large variability in GMSL throughout the Pleistocene. Here we assess these reconstructions from an energy balance perspective by using them to force a global carbon cycle model in different scenarios ...

A Framework to Identify Rock Glaciers and Model Mountain Permafrost in the Jhelum Basin, Kashmir Himalaya, India

Earth and Space Science
Deglaciation has led to the transformation of glaciers into rock glaciers in various mountainous regions worldwide. However, the science of permafrost and rock glaciers remains under‐researched in the Himalayan region.

Holocene Hydroclimatic Variations Over Western and Central Asia as Inferred From Speleothem Isotope Evidence

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Recent studies have found a dipole pattern of hydroclimate variation in western Asia (WA) and arid central Asia (ACA) during the Holocene. However, speleothem δ18O evidence shows some inconsistencies with other lines of evidence, especially concerning the timing of peak wetness in WA and precipitation trends in ACA.

Collisions with ice-volatile objects: Geological implications [PDF]

The collision of the Earth with extra-terrestrial ice-volatile bodies is proposed as a mechanism to produce rapid changes in the geologic record. These bodies would be analogs of the ice satellites found for the Jovian planets and suspected for comets ...

Retracing the Response of Rangifer to Postglacial Climate Change in Arctic Islands

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Our study examines the role of sea ice and glacial retreat in shaping the biogeography of Rangifer tarandus across Arctic islands since the last glacial period. Using mitochondrial DNA analysis and approximate Bayesian computation (ABC) modelling, we found that Arctic island dispersal occurred during the Holocene, with sea ice cover likely influencing ...

A framework for in‐stream jams formed by snow avalanche‐delivered large wood

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Large wood delivered by avalanches organizes into blanket or transport jam complexes.Jam complexes increase channel width and promote pool and bar formation. Avalanche frequency and magnitude, which are dependent on hillslope angle and roughness characteristics, controls jam complex type.

Slumping and Sediment Storage at the Shelf‐Edge: A Case Study From the Kookfontein and Waterford Formations, Tanqua Karoo Depocenter, South Africa

Basin Research, Volume 38, Issue 2, March/April 2026.
Block model of Tanqua shelf‐edge delta formation at Katjiesberg, illustrating key stratigraphic features and system relationships interpreted from the Kookfontein‐Waterford formations. Schematic lines A‐E correspond to locations of measured sections. ABSTRACT A low‐gradient shelf‐edge delta system preserved at the Katjiesberg outcrop in the northern ...

From Snowferner to no ferner: The deglaciation of Zugspitzplatt

Annals of Glaciology
The Zugspitzplatt represents a key high-alpine reference landscape in German geography. Located below the Zugspitze, Germany’s highest peak, it still hosts some of the country’s small remaining glacier ice reserves.

Analytical investigation of the decrease in the size of the habitable zone due to limited CO$_2$ outgassing rate

, 2016
The habitable zone concept is important because it focuses the scientific search for extraterrestrial life and aids the planning of future telescopes. Recent work has shown that planets near the outer edge of the habitable zone might not actually be able

Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden [PDF]

, 2006
The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed ...
