Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

open access: yesSedimentology, Volume 73, Issue 3, Page 706-741, April 2026.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

De‐Densification and Decoupling Trends in the Relationship Between Population and Built‐Up Areas: A GIS Model Beyond Administrative Boundaries (Spain, 1975–2020)

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT Space–time demographic and built‐up trends are crucial in the European challenge of socio‐territorial cohesion and the Urban Agenda. This research aims to analyze the space–time patterns of population and built‐up areas in Spain between 1975 and 2020, without the constraints imposed by administrative boundaries. To this end, we used the freely

Characteristics of Intense Multi‐Day Wet Spells Over West Africa

open access: yesInternational Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
The study reveals a significant increase in intense wet spells, particularly in KASS‐D, emphasising the value of dense rain‐gauge networks. Larger‐sized events have grown, while smaller ones declined, boosting 3‐day and 5‐day wet spells' contribution to annual rainfall, with the Guinea Coast showing the highest increase and the Sahel the lowest ...

Trends and Circulation Conditions of Precipitation Over the Sudeten Mountains (Central Europe) in the Years 1961–2020

open access: yesInternational Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
Significant trends of precipitation totals are visible at seasonal (negative in spring and positive in winter) and monthly level. The deepening rainfall deficit in April in Western Sudetes threatens the stabilisation of forest ecosystems, the preservation of biodiversity and significantly limits water resources for economic use.

Transient Evolution of Polar Amplification Under Different CO2 Ramping Rates

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Polar amplification is a robust feature of greenhouse‐gas‐forced climate change. Previous studies have typically examined it over a fixed time period or following an abrupt increase in atmospheric CO2 ${\text{CO}}_{2}$. Here, we investigate how the transient evolution of polar amplification depends on the rate of atmospheric CO2 ${\text{CO}}_ ...
