Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Schumpeter au Sahel

, 1993
La formulation "Schumpeter au Sahel" peut à première vue paraître surprenante. Les réflexions et analyses de Schumpeter ont porté sur des phénomènes d'innovations et de développement qui se sont produits dans le contexte de formations sociales (le développement du capitalisme industriel en Europe) sensiblement différentes des situations rurales ...

Satellite‐Derived Leaf Photosynthetic Capacity Data Set Improves Atmospheric Inversion of Terrestrial Carbon Fluxes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurately estimating the terrestrial carbon sink is crucial for understanding the global carbon cycle. Here, we examine how different parameterizations of the key leaf photosynthetic capacity parameter, namely the maximum Rubisco carboxylation rate normalized to 25°C (Vcmax25), influence terrestrial carbon flux estimates within an atmospheric

Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Understanding the Zonal Variability in Projections of Sahel Precipitation

Geophysical Research Letters
The uncertainty in precipitation projections across the Sahel has persisted across generations of climate models. Many projections show a zonal dipole in the sign of precipitation change, with wetting across the Central Sahel and drying across the ...

Reversal of the ITCZ Shift During the Satellite Era

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract A southward shift of the Intertropical Convergence Zone (ITCZ) during the latter half of the 20th century has been primarily attributed to interhemispheric differences in anthropogenic aerosol forcing. However, in recent decades anthropogenic aerosol emissions have declined, particularly over Northern Hemisphere (NH).

Pattern Recognition of West African Monsoon Extreme Rainfall Events Using Convolutional Neural Networks

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurate prediction of extreme rainfall and dry events remains a major challenge in West Africa due to the complex and non‐linear dynamics of the monsoon system, which involve interactions among local convection, large‐scale circulation, ocean‐atmosphere coupling, and intra‐seasonal variations.

Seasonal Prediction Skill Contrasts of Subtropical North Atlantic Sea Surface Temperature Anomalies Under Different AMV Phases

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Atlantic multidecadal variability (AMV) exerts profound climatic influences on both local and remote regions. Recent studies show that AMV can significantly modulate the El Niño–Southern Oscillation (ENSO) and its teleconnections. However, few studies have examined AMV impacts on seasonal prediction skill.

Tribes and Trafficking: Trans-Saharan Illegal Trade Routes as a Conflict Factor in the Sahara-Sahel Region

Международная аналитика
The conflict in the Sahel that began in 2012 is closely linked to the phenomenon of trans-Saharan illicit trade routes through Mali, Niger and Libya.
