South Asian river basins in a 1.5 °C warmer world

Abstract

The study provides a regional quantitative assessment of the impacts of global warming for a major global climate change hotspot: the Indus, Ganges, and Brahmaputra river basins (IGB) in South Asia, by analyzing changes in climate change indicators based on 1.5 and 2 °C global warming scenarios. The model uses an ensemble of downscaled general circulation models, representative for the complete set of climate change projections in the Coupled Model Intercomparison Project Phase 5 (CMIP5) multi-model archive, related to the IGB region. It does not include future changes in sea level rise.
