Declining groundwater storage expected to amplify mountain streamflow reductions in a warmer world

Nature Water, Journal Year: 2024, Volume and Issue: 2(5), P. 419 - 433

Published: May 23, 2024

Abstract Groundwater interactions with mountain streams are often simplified in model projections, potentially leading to inaccurate estimates of streamflow response climate change. Here, using a high-resolution, integrated hydrological extending 400 m into the subsurface, we find groundwater an important and stable source historical mountainous watershed Colorado River. In warmer climate, increased forest water use is predicted reduce recharge resulting storage loss. Losses expected be most severe during dry years cannot recover levels even simulated wet periods. depletion substantially reduces annual intermittent conditions when precipitation low. Expanding results across region suggests declines will highest Headwater Gunnison basins. Our research highlights tight coupling vegetation dynamics that excluding explicit warming may underestimate future reductions streamflow.

Advances in Defect Engineering of Metal Oxides for Photocatalytic CO₂ Reduction

Small, Journal Year: 2024, Volume and Issue: unknown

Published: April 30, 2024

Abstract Photocatalytic CO 2 reduction technology, capable of converting low‐density solar energy into high‐density chemical energy, stands as a promising approach to alleviate the crisis and achieve carbon neutrality. Semiconductor metal oxides, characterized by their abundant reserves, good stability, easily tunable structures, have found extensive applications in field photocatalysis. However, wide bandgap inherent oxides contributes poor efficiency photocatalytic reduction. Defect engineering presents an effective strategy address these challenges. This paper reviews research progress defect enhance performance summarizing classifications, preparation methods, characterization techniques. The focus is on engineering, represented vacancies doping, for improving oxide photocatalysts. includes advancements expanding photoresponse range, enhancing photogenerated charge separation, promoting molecule activation. Finally, provides summary current issues challenges faced along with prospective outlook future development technology.

Rainfall‐Driven Extreme Snowmelt Will Increase in the Tianshan and Pamir Regions Under Future Climate Projection

Journal of Geophysical Research Atmospheres, Journal Year: 2025, Volume and Issue: 130(1)

Published: Jan. 2, 2025

Abstract Snowmelt and related extreme events can have profound natural societal impacts. However, the studies on projected changes in snow‐related extremes across Tianshan Mountains (TS) Pamir regions been underexplored. Utilizing regional climate model downscaling bias‐corrected CMIP6 data, this study examined snowmelt water available for runoff (SM ROS , rainfall plus snowmelt) during cold seasons these historical (1994–2014) future (2040–2060) periods under shared socioeconomic pathway (SSP) scenarios (SSP245 SSP585). The results demonstrated that accumulated was to rise by 17.98% 20.36%, whereas SM could increase 26.97% 28.95%, respectively, SSP245 SSP585 scenarios. Despite relatively minimal snowmelt, magnitude of daily maximum (10‐year return level) 28.04 mm expected 15.32% 15.31% scenarios, especially western TS exceeding 26%. Meanwhile, areas with a 50 over 13.5%. A notable its area occupation high intensity highlighted an increased risk rainfall‐driven events. absolute snowfall frequent snow‐rain phase transitions season warming (SSP245: 2.19°C SSP585: 2.22°C) benefits high‐intensity rain‐on‐snow events, leading augmentation. findings emphasize significant role rainfall‐trigger exacerbating climate.
