Observational Uncertainty in Deep Learning Climate Downscaling and Projections

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Deep learning (DL) models are increasingly used for climate downscaling, yet the impact of observational uncertainty on their performance remains poorly understood. Here we assess this effect by training ensembles of DL downscaling models using four independent gridded observational data sets over continental Spain that differ in source ...

The Fate of Western Headwaters: Climate Controls on Base‐Flow Decline

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Headwater streams comprise nearly 88% of the western U.S. river network and supply most of the region's surface water, making them especially sensitive to warming, snowpack loss, and drought. As surface‐water inputs decline, groundwater increasingly sustains streamflow, elevating the need to understand long‐term trends in base flow and their ...

Tidal Inundation Decreases Carbon Dioxide Exchange in an Irish Atlantic Saltmarsh

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Despite the growing interest in carbon cycling in tidal‐wetland ecosystems we lack sufficient understanding of the degree to which saltmarsh ecosystems sequester carbon and the ecosystem dynamics of carbon dioxide (CO2) exchange, especially with tidal influence.

High-Resolution Speleothem-Based Palaeoclimate Records From New Zealand Reveal Robust Teleconnection To North Atlantic During MIS 1-4

, 2008
Growth rates, δ18O and δ13C of five stalagmites from the west coasts of North and South Islands, New Zealand, provide records of millennial-scale climate variability over the last ~75 kyr.

Jensen's Inequality Quantifies How Temporal Averaging of Moisture Inputs Affects Modeled Soil Respiration Across Continental Scales

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Understanding how temporal patterns of moisture and temperature variability influence biogeochemical responses remains a central challenge in modeling the Earth system. Jensen's inequality provides a mathematical framework for quantifying when nonlinear processes cause the response to average conditions to differ systematically from the ...

Spatial Patterns and Controlling Factors of River Flow Intermittency in Africa

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding river flow intermittency remains a major challenge in data‐scarce regions such as Africa. This study presents the first high‐resolution, four‐class intermittency map of African rivers using a sequential modeling approach based on Random Forest. A binary model (BC‐UNS) distinguishes perennial from non‐perennial reaches across 15.5

Ecological Niche Divergence in an Invasive Non‐Native Shrub: Implications for Risk Assessments

Austral Ecology, Volume 51, Issue 6, June 2026.
The worldwide spread invasive shrub Nicotiana glauca (tree tobacco) underwent divergent niche shifts across two of its invaded regions. In the mediterranean region it presents high thermal seasonality and low thermal seasonality in the Caatinga (Brazil).

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

The Fungal Community of a High‐Arctic Semi‐Desert Ecosystem Is Robust to Two Decades of Doubled Summer Precipitation but Influenced by Plant Dominance

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT In high‐arctic semi‐desert ecosystems, climate projections suggest a doubling of the current ≤ 250 mm annual precipitation by 2075, increasingly falling as summer rain. This is expected to affect the balance among fungal ecological groups and stimulate decomposition over build‐up of soil organic matter.

Examining the impact of dry climates temperatures on citrus fruit internal ripening

[EN] High temperatures alter the ripening process of citrus fruit, affecting quality, favor, harvest time and marketing period. For example, citrus fruits ripen faster and are sweeter in tropical hot-humid climates than in Mediterranean warm-dry climates
