Global Climatic Zones in the Last Glacial Maximum Estimated From Assimilated Temperature Data

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
This study estimated Global Climatic Zones (GCZs) during the Last Glacial Maximum (LGM) using assimilated temperature data and the k‐means++ machine learning method for enhanced objectivity. Present‐day GCZ boundaries were determined and then applied to the LGM data, which was 6°C cooler globally. Results showed all LGM zones shifted toward the equator,

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 ...

The linkage between autumn Barents-Kara sea ice and European cold winter extremes

Frontiers in Climate
While the Arctic's accelerated warming and sea ice decline have been associated with Eurasian cooling, debates persist between those attributing this to sea ice retreat and those to internal variability.

Pleistocene Forest Stability Predicts Patterns of Frog Diversity in Central Africa

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Using high‐resolution paleoclimate reconstructions, we quantified habitat stability for Central African rainforests across 257 time slices since the early Pleistocene. Stacked projections of forest‐dependent frog niches identify both a large, continuous refugium and smaller, highly stable forest blocks embedded within today's forest cover.

New Species of Babinskaiidae (Insecta: Neuroptera) From the Mid‐Cretaceous of Myanmar and the Morphological Divergence of the Family Across the Cretaceous

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Two new species of Babinskaiidae are reported from the mid‐Cretaceous of Myanmar and the morphological divergence of the family across the Cretaceous is quantified. The Babinskaiidae assemblages from the Lower Cretaceous Crato Formation and the Upper Cretaceous Kachin amber are separated by a pronounced morphological divergence in both overall size and

Beyond Geography: Climatic Gradients Shape Reeves's Muntjac Population Structure in Taiwan

Ecology and Evolution, Volume 16, Issue 3, March 2026.
North–south population split in Reeves's muntjac revealed by genome‐wide SNPs. Parallel divergence patterns across mammals in Taiwan suggest shared environmental drivers. Demographic modeling supports historical isolation and asymmetric gene flow.

How Will Tropical Pacific Trends Affect the Future of the Southern Annular Mode?

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract The Southern Hemisphere extratropical atmospheric circulation has experienced a strong positive trend in the Southern Annular Mode (SAM). Understanding the cause of this change is crucial for projecting future regional climate change. Here, we analyze the contributing factors to the trend in the SAM under both historical and future conditions.

Diagenetic Effect on Planktic Foraminiferal Mg/Ca Records in the Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Mg/Ca ratios in planktic foraminifera have long been used as a thermometer to reconstruct the past climate. However, this study revealed that in certain intervals, the Mg/Ca ratios of the planktic foraminifer Neogloboquadrina pachyderma, a widespread species in the Arctic Ocean, displayed anomalously high values which could severely bias paleo‐

Lessons from paleoclimates for recent and future climate change: opportunities and insights

Frontiers in Climate
Paleoclimate information has played an instrumental role in showing how fast climate can vary and how large these changes can be. It provided the first vivid demonstration of the relationships between atmospheric greenhouse gas concentrations and surface

Geochemical Analysis of Diachronous V‐Shaped Ridges and Troughs That Flank the Reykjanes Ridge South of Iceland

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.
