Paleoclimate Variations Spanning the Past 29–4 Ma Inferred From Lipid Biomarkers and Carbon Isotopes in the Linxia Basin, Northeast Tibetan Plateau

open access: yesFrontiers in Earth Science, 2022
Thick and continuous deposits in the Linxia Basin, located in the landing area of westerlies and monsoons, offer a good opportunity for understanding the climatic evolution and tectonic activities.

Tree Rings Indicate Potential for Severe Soil Moisture Drought in California Is Much Greater Than Observations Suggest

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Tree rings reveal that 1579–1580 was by far the driest pair of years across California since at least CE 1100. Here we produce a gridded tree‐ring reconstruction of summer soil‐moisture anomalies for California and perform a peaks‐over‐threshold extreme value analysis on statewide mean drought severity from CE 1100–2025.

Continental-scale bias correction and random forest downscaling of CMIP6 precipitation across Europe

open access: yesGeocarto International
This study evaluated bias-correction-based downscaling approaches for precipitation data from 11 high-resolution CMIP6 models across Europe. The empirical quantile mapping technique demonstrated superior performance by aligning the model outputs with ...

PaleoRec: A sequential recommender system for the annotation of paleoclimate datasets

open access: yesEnvironmental Data Science, 2022
Studying past climate variability is fundamental to our understanding of current changes. In the era of Big Data, the value of paleoclimate information critically depends on our ability to analyze large volume of data, which itself hinges on ...

From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania

open access: yesInternational Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.

Timing of the Recent Migration and Intensification of the Southern Hemisphere Westerly Winds

open access: yesGeophysical Research Letters
In recent decades, the Southern Hemisphere westerly winds have strengthened and migrated south, attributed to greenhouse gas emissions and stratospheric ozone depletion. However, the onset and acceleration of these drivers is coincident with the start of
