A 41-year satellite record reveals abrupt redistribution of the Okavango Delta’s flood pulse since 2012

A 41-year satellite record reveals that since 2012, the Okavango Delta's flood pulse has undergone an abrupt, system-wide redistribution toward the northeast, driven by extreme climate variability and tectonic subsidence, which threatens the livelihoods of southwestern communities and may eventually isolate the delta from the Zambezi basin.

Evaluating WRF-Derived Wet Bulb Globe Temperature Using Component Pathways, Wind-Height Adjustment, and Grid-Spacing Sensitivity

This study evaluates a WRF-based post-processing framework for estimating outdoor Wet Bulb Globe Temperature (WBGT) in San Marcos, Texas, finding that while the Liljegren pathway generally offers the best full-day performance, the optimal configuration depends on the specific observational dataset, grid resolution, and whether the focus is on full-day averages or daily maximum heat stress.

Extreme heat and snow drought preconditioned the August 2026 Nepal rock–ice avalanche flood

This study reveals that the August 2026 Nepal rock–ice avalanche flood was preconditioned by an exceptional combination of extreme atmospheric heat and acute seasonal snow drought, highlighting a critical climatic pathway to mountain hazards that extends beyond traditional rainfall or geological triggers.

Magnitude Compression at Two Completeness Thresholds and the Likelihood of Large Earthquakes: Pre-registered Tests of Blue-Dominance and Red-Persistence Rules

This pre-registered study analyzing earthquake catalogues from Japan, Chile, and Turkey found that while a "blue-dominance" rule (where magnitude compression at a lower threshold exceeds that at a higher threshold) successfully identified periods of significantly reduced large earthquake likelihood, none of the tested rules could reliably predict the approach of large earthquakes.

Planetary Energy Imbalance, ENSO Variability and Cryospheric Instability: A Multi-Scale Analysis of Himalayan Climate Risk and the 2026 Nepal Flood

This study employs a multi-scale analytical framework to demonstrate that the 2026 Nepal flood was not caused by a single factor like planetary energy imbalance or ENSO, but rather emerged from the complex interaction of long-term cryospheric warming, permafrost degradation, and short-term hydrometeorological triggers within a multi-hazard context.
