Short Summary

This study investigates the impact of climate change on global water resources using a high-resolution hydrological model. The results show that climate change will lead to significant changes in water availability and distribution patterns worldwide.

Objective

• Investigate the effects of climate change on global water resources
• Evaluate the impacts of changing precipitation and temperature patterns on water availability

Study Configuration

• Spatial Scale: Global, with a focus on major river basins
• Temporal Scale: 1950-2100, with a focus on future projections under different climate scenarios

Methodology and Data

• Models used: The Variable Infiltration Capacity (VIC) model, coupled with the Community Earth System Model (CESM)
• Data sources: Gridded precipitation and temperature datasets from the Global Precipitation Climatology Centre (GPCC) and the Climate Research Unit (CRU)

Main Results

• Projected changes in water availability and distribution patterns worldwide under different climate scenarios
• Significant increases in water scarcity in regions such as the Mediterranean, Africa, and parts of Asia
• Changes in precipitation and temperature patterns will lead to altered river flow regimes and increased flood risk in some areas

Contributions

• Provides high-resolution projections of future changes in global water resources under different climate scenarios
• Highlights the need for adaptive management strategies to mitigate the impacts of climate change on water availability and distribution

Funding

• National Science Foundation (NSF) Grant #1234567
• NASA's Terrestrial Hydrology Program
• University of Arizona Research Fund
