QUEST GSI provides quantitative model simulations assessing global-scale climate change impacts across multiple sectors. The methodology constructs scenarios from various climate models under different emissions pathways and fixed global temperature changes. Impacts are estimated for water resources, flooding, crop productivity, food security, ecosystem productivity, and human health at regional and global scales.
Use Cases
- Assessing water resource stress based on climate and run-off scenarios
- Estimating crop productivity and food security impacts under different emissions pathways
- Modeling fluvial and coastal flood risk from projected climate changes
- Evaluating avoided impacts from specific emissions policies using the developed methodology
Strengths
- Project led by a principal investigator from the University of Reading with co-investigators from nine other UK research institutions
- Methodology designed for application to other climate scenarios representing specific policy objectives
- Provides quantitative impact information distributed across the world
Limitations
- Metadata completeness is low: column names, row counts, size, license, and author information are unknown
- Impact estimates in some sectors, particularly in south Asia, are noted to have high uncertainty due to projected rainfall changes
