Nonstationary Flood Frequency Analysis Using Reconstructing Past Millennium Floods Based on Large‐Scale Climate Indices

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT With global climate change and human activities, environmental uncertainties are increasing, and extreme flood events are occurring more frequently. The reliability of traditional hydrological frequency analysis theories, based on the assumption of stationarity, is being increasingly questioned.

Post-2000 greening of Kalahari Desert and southern African grasslands reduces food and economic insecurity in Africa

Environmental Research Letters
The Kalahari high-pressure system that forms the Kalahari and Namib Deserts of Southern Africa is maintained by the sinking motion of the Hadley circulation.

Small understory trees increase growth following sustained drought in the Amazon

New Phytologist, Volume 249, Issue 6, Page 2787-2799, March 2026.
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Projected Late 21st Century Warming Unprecedented in Northwest China in a Holocene Context

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Northwest China is facing socio‐environmental challenges linked to ongoing climatic warming. However, a scarcity of regional paleorecord syntheses limits our understanding of natural long‐term climate variability in the region and hinders the contextualization of contemporary warming.

Contributions of external forcing and internal variability to the multidecadal warming rate of East Asia in the present and future climate

npj Climate and Atmospheric Science
External forcing and internal variability contribute to multidecadal variation in the warming rate of East Asia. By rescaling the Coupled Model Intercomparison Project Phase 6 multi-model mean to the temperatures observed for the 1890–2020 period, we ...

Preferred Time Scales of Pacific Decadal Variability During the Last Millennium Related to Volcanic Activity

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pacific Decadal Variability (PDV) plays a significant role in modulating the global climate change on decadal time scale. Although various reconstructions of the PDV have been developed for the last millennium, preferred time scales of the PDV and mechanisms behind them remain unresolved. Here, we combine a δ18O‐based PDV index derived through

Landward Acceleration of Tropical Cyclones Making Landfall Along the South China Coast

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Accurate forecasts of near‐landfall TC characteristics (direction, translation speed, and intensity) are essential for timely disaster preparedness. Using best‐track data (1951–2023), this study reveals a significant pre‐landfall acceleration of TCs along the South China coast, with translation speed increasing by 35.5% and 16.4% during the 24

Emerging Effective Radiative Forcing in the Radiative Imbalance Since 2010

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Satellite observations indicate a substantial increase in Earth's top‐of‐atmosphere (the top of the atmosphere (TOA)) radiative imbalance since 2010. We estimate trends in effective radiative forcing (ERF) by separating TOA flux changes into forcing and response components, using feedback parameters derived from observed and simulated ...

Atlantic multidecadal variability control on European sea surface temperatures is mainly externally forced

Environmental Research Letters
The semi-enclosed European seas (Baltic Sea, North Sea, Mediterranean Sea, and Black Sea) have been among the fastest warming seas worldwide during the last decades.

Recent Increasing Trend in October–November Caribbean Tropical Cyclone Activity

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract October–November Caribbean tropical cyclone (TC) activity has significant impacts for both the Caribbean islands and Central America (e.g., Hurricanes Eta and Iota in 2020). October–November Caribbean TCs can also track northward and make continental United States landfall, resulting in substantial damage and fatalities (e.g., Hurricane ...
