Twenty Years of Aerosol Optical Depth over Cairo, Egypt (2005–2025): A Comprehensive Climatology Using AERONET and MODIS Observations

This study presents the first unified 20-year (2005–2025) aerosol climatology for Cairo, Egypt, utilizing AERONET and MODIS data to reveal a statistically significant decreasing trend in aerosol optical depth while characterizing distinct seasonal regimes driven by Khamaseen dust and agricultural burning.

Timing and cause of early Late Pleistocene megadrought in eastern Africa

Using sedimentary data from Lake Chala, researchers reconstructed climate evolution in eastern equatorial Africa to reveal that a unique convergence of high atmospheric moisture deficit and cool Arabian Sea temperatures caused a severe megadrought between 110 and 97 kyr ago, potentially triggering early modern human dispersal despite prevailing interglacial warming trends.

ClimDiT: A Generative Latent Diffusion Transformer Framework for Multivariate Climate Downscaling

ClimDiT is a novel generative framework based on latent diffusion transformers that overcomes the limitations of traditional regression-based downscaling by producing high-resolution, spatially coherent, and probabilistically calibrated multivariate climate projections for the Iberian Peninsula.

Analysis of Deformation Characteristics and Controlling Factors of the Upper Combined Structure: A Case Study of the Structural Physics Simulation Experiment in the Zhongqiu-Dongqiu Area of Kuqa Depression

This study utilizes structural physics simulations to demonstrate that the thickness and distribution of gypsum-salt layers, which transition from double to single salt zones, are the primary controlling factors determining the deformation styles (ranging from high-angle faults to imbricate structures) and trap evolution in the supra-salt strata of the Zhongqiu-Dongqiu area in the Kuqa Depression.

The global limits of sustainable irrigation as an adaptation to climate change

This study uses an integrated modeling framework to demonstrate that while sustainable irrigation can enhance agricultural adaptation under low warming by improving efficiency, intensifying climate change will shift irrigation toward dependency, ultimately revealing that water availability—not agronomy—defines the hard limits of this adaptation strategy by 2050.
