Decadal climate variability and increasing exposure of Chilean agriculture
Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.Abstract Central Chile has undergone a steady shift from traditional annual crops to fruit orchards and vineyards, and a decline in the area dedicated to annual crops. This transition coincides with a decrease in precipitation and an increase in temperature.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Controls on Valley‐Floor Width in the Western Andes
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.Abstract Global warming is causing rapid and profound impacts on northern ecosystems. Shifting precipitation, permafrost thaw, and rapid shrub advance into tundra environments are combining to alter stream temperature in uncertain ways. The expansion and increased abundance of shrub vegetation, termed shrubification, may moderate warming stream ...

Earth's Future, Volume 14, Issue 6, June 2026.Abstract High‐altitude wetlands are critical ecosystems that store water, regulate downstream flows, and sustain biodiversity. Their persistence is tightly linked to continuous water inputs from precipitation, groundwater, snow and glacier melt, making them highly vulnerable to climate‐driven shifts in mountain hydrology. Rapid glacier retreat, altered
