Wave climate and atmospheric forcing of the Brazilian Equatorial Margin

This study characterizes the wave climate and atmospheric forcing of the Brazilian Equatorial Margin using WAVERYS reanalysis and buoy data to identify six distinct, seasonally varying wave regimes driven by a combination of remote Atlantic swell, local trade winds, and specific atmospheric pressure anomalies.

Long-term fate of arsenic pollution in subtropical agricultural soils

This study reveals that in subtropical red-soil critical zones, agricultural arsenic pollution is not confined to surface layers but migrates downward to accumulate predominantly in deep, iron-oxide-rich reticulate red clay horizons, challenging the misconception that such contaminants are primarily eroded into oceans.

Understanding ENSO asymmetry with a reduced stochastic model: deterministic nonlinearity and multiplicative noise

This study employs a reduced stochastic model derived from daily observations to demonstrate that nonlinear deterministic drift, rather than state-dependent noise, is the primary mechanism driving ENSO asymmetry, a finding that also explains intermodel differences in CMIP6 simulations through variations in effective SST damping.

Coastal landscape dynamics in the Mouths of Cameroon and adjacent watersheds: morphological, environmental, and socio-ecological challenges

This study characterizes the geomorphological and socio-ecological dynamics of the Mouths of Cameroon by integrating multi-temporal remote sensing and field data to reveal how the interplay between natural coastal processes and intensifying human pressures, such as urbanization and land-use change, drives shoreline instability and environmental degradation across the estuary and its adjacent watersheds.

From viruses to mesozooplankton: succession and trophic lags during the spring bloom in the Arctic under climate change transition

This study reveals that despite climate change concerns, the 2023 Arctic spring bloom in Kongsfjorden followed a typical trophic succession driven primarily by nutrient depletion and grazing pressure rather than temperature, highlighting the need for higher-resolution monitoring to fully understand polar ecosystem responses.

Hydroclimatic Mediation of Low-Frequency Solar Activity Signals in Spanish Cereal Yield Variability (1961–2021)

This study demonstrates that low-frequency solar activity indirectly influences Spanish cereal yields from 1961 to 2021 not through direct biophysical effects, but by weakly modulating winter North Atlantic Oscillation patterns, which subsequently alter Mediterranean precipitation and soil moisture with a three-year lag to drive interannual yield variability.

Traditional Medicinal Knowledge and Climate Change Perceptions: Insights from the Cholanaickan Community, a Particularly Vulnerable Tribal Group in India

This study reveals how climate change and environmental degradation threaten the traditional medicinal knowledge of India's Cholanaickan PVTG while highlighting their resilience and the urgent need to integrate Indigenous practices into climate adaptation policies.
