Enhanced Interdecadal Variability in the WACE and Its Oceanic Drivers

open access: yesGeophysical Research Letters
As the Earth warms, the “warm Arctic–cold Eurasia” (WACE) has changed noticeably, with enhanced interdecadal variability as the Arctic heats up, particularly over the Barents–Kara Sea region.

Diagnosing CESM2 Biases in Northwest Indian Ocean Warming and Its Implications for India Summer Monsoon Precipitation

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Declining monsoon rainfall over agriculture‐dependent Eastern Central India (ECI) during 1901–2014 threatens regional food and water security. Observations link ECI drying to rapid Northwest Indian Ocean (NWIO) warming, which weakens monsoon circulation.

The potential of gypsum speleothems for paleoclimatology: application to the Iberian Roman Humid Period

open access: yesScientific Reports, 2020
Carbonate cave deposits (speleothems) have been used widely for paleoclimate reconstructions; however, few studies have examined the utility of other speleothem-forming minerals for this purpose.

Glacier‐Climate Feedbacks Modulate Last Glacial Maximum Dust Cycle Over the Third Pole

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Geological records indicate only a modest Last Glacial Maximum (LGM) increase in dust deposition over the Third Pole (TP), in contrast to the order‐of‐magnitude rise at high latitudes. Existing climate simulations, which generally prescribe present‐day or no TP glaciers, have struggled to reproduce this muted response.

Evaluating the Role of Kernel Choice on Radiative Feedback Estimates

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Radiative feedbacks are important for understanding climate sensitivity, yet estimates vary widely across climate models. Feedbacks are often computed using the radiative kernel technique, which uses pre‐calculated radiative sensitivities (kernels) derived from different models and base states. While much attention has been given to intermodel

Dynamical structure in paleoclimate data

open access: yes, 1995
Deterministic chaos in dynamical systems offers a new paradigm for understanding irregular fluctuations. The theory of chaotic dynamical systems includes methods that can test whether any given set of time series data, such as paleoclimate proxy data ...

Paleoclimate delineation using magnetic susceptibility data

open access: yes, 2008
© Philip G. Chase, André Debénath, Harold L. Dibble, and Shannon P. McPherron 2009. INTRODUCTION This chapter reports on the use of the technique of magnetic susceptibility (MS) on sediments found in Fontéchevade Cave to describe the paleoclimate of the ...

Deep‐Time Paleoclimate Proxies

open access: yesAGU Advances, 2020
Pre‐Cenozoic climate (>66 million years ago) has been reconstructed with climate sensitive sedimentary deposits. However, sedimentary records are inherently local and can be affected by topography and oceanic and atmospheric currents.

Tracing Ancient Migration Routes: Did Gloydius Pitvipers Disperse Across Paleo‐Tibet Through Temperate and Subtropical Corridors?

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We investigated the evolutionary and biogeographic history of Himalayan and Hindu Kush Gloydius pitvipers by integrating time‐calibrated phylogenetic analyses with paleoclimatic reconstructions and species distribution modeling. Our results suggest an early Miocene origin in East and Southeast Asia, followed by westward dispersal across Paleo‐Tibet via

Temperature extremes across elevation gradients: evidence from two German mountain observatories

open access: yesFrontiers in Earth Science
Mountain regions are warming rapidly, yet long records across elevation are rare. This study presents the first comprehensive assessment of temperature extremes across an elevation gradient in the Bavarian Alps at two long-term observatories ...
