Runoff Reconstructions and Future Projections Indicate Highly Variable Water Supply From Pacific Rim Water Towers

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Anthropogenic climate change affects regional hydrological cycles and poses significant challenges to the sustainable supply of freshwater. The Central China water tower (CCWT) is the key source region feeding the Yangtze and Yellow Rivers, and its runoff is indispensable for the surrounding mega‐city clusters. Here we present a reconstruction

Impacts of Climate Change and Human Activities on Global Mountain Grasslands: Insights Into the Last Two Decades and Future Climate Scenarios

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Mountain grasslands are vital ecosystems providing critical services such as carbon sequestration, water regulation, and biodiversity conservation. However, these ecosystems are increasingly threatened by climate change and human activities. This study evaluates vegetation dynamics in global mountain grasslands (2000–2021) using remote sensing

Transition in Global Basins From Precipitation‐Dominated to Evaporative Demand‐Dominated Meteorological Drought: Past Patterns and Future Projections

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Meteorological drought, one of the most destructive natural hazards, is driven by both precipitation deficits and high evaporative demand. While precipitation has traditionally been considered the dominant driver, recent studies suggest an increasing influence of evaporative demand.

PrecipFusionNet: A Unified Deep Learning Model for Improving Numerical Precipitation Prediction

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Numerical weather prediction (NWP) often suffers from substantial biases when forecasting extreme rainfall. Traditional corrections tend to underuse spatial information, while deep learning approaches typically struggle with data imbalance for rare events.

Evaluating the Performance of Uni‐ and Multivariate Bias Correction Techniques: Challenges in Preserving Temporal and Dependence Structures

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Global Climate Models (GCMs) are essential for simulating past and future climates but suffer from systematic biases and coarse resolution, limiting direct applications. Bias correction (BC) and downscaling, using dynamical or statistical methods, address these issues. Quantile mapping (QM)‐based BC is widely used, yet it distorts dependencies,

Mapping area of habitat for inland wetland species

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Area of habitat (AOH) maps provide a high‐resolution representation of the habitat available in a species’ range and can support conservation policy and planning processes. However, until recently, there was insufficient knowledge on the distribution of inland wetlands and freshwater biodiversity to develop AOH mapping methods specifically ...
